Cell Phone GPS Tracking Basics

GPS on cell phones is what people generally consider when investigating tracking cell phones. GPS (Global Positioning System) using satellites is the most known and more precise means of tracking. But, GPS must have satellites to be in direct line of site of the handset. It doesn’t work really well indoors or in dense metropolitan areas. In the event that the mobile phone is in a structure, for example your school, shopping center, or often sitting in an automobile the signals may not reach the smart phone. Often thick cloud cover and dense trees impedes with signals. Some mobile phones may hold on to the last known GPS position, others may not.

Some important technical capabilities relevant to GPS cell phone tracking to consider include: Tracking Application “Persistence”. The tracking application on a cell phone typically must be enabled by the user. Depending on the handset, the application may persist – remaining enabled when the phone is turned on after having been turned off. This feature can be especially important if cell phone tracking is worthwhile and you do not want to require the person using the phone to turn tracking on and off. Another thing relevant to Tracking Application “Persistence” and smartphone GPS location is the potential of battery drain. It is important to be able to remotely adjust the frequency of taking GPS position. Choosing real-time or periodic sampling affects both the resolution of finding position along with battery life. One common method of minimizing battery and data use is Passive Tracking. Some cell phone GPS tracking devices will store location data internally so that it can be downloaded when convenient. Also known as “data logging,” which can maintain position information even when the device has traveled outside the wireless network. Passive tracking is not a universal feature built-in to standard cell phone, but the most up-to-date mobile phones tend to have Passive tracking capability.

A lot of the discussion surrounding cell tracking, mobile GPS and mobile phone track software could be helped by a GPS Satellite primer.

GPS satellites broadcast signals from space that GPS receivers utilize to provide three-dimensional location (latitude, longitude, and altitude) plus precise time. GPS stands for Global Positioning System and is a system that is composed of 3 main segments: Space Segment, Control Segment and User Segment.

The GPS Space Segment is composed of twenty-four to thirty-two satellites that orbit the earth in medium earth orbit MEO. These satellites are referred to as the GPS Constellation, and they are orbiting twice a day. They are not geostationary, they travel at over 7,000 mph. They are solar powered but have battery backup for when they are in the earth?s shadow. They are positioned so that there are at least 4 satellites ?visible? from any point on earth. Small rocket boosters on each satellite keep them properly positioned. The satellites last about ten years until all their fuel is exhausted.

GPS Satellites are not communications satellites. Geostationary or communications satellites are parked in space 22,300 miles above the equator. These satellites are used for weather forecasting, satellite TV, satellite radio and most other types of global communications. At exactly 22,000 miles above the equator, the earth’s force of gravity and centrifugal forces are offset and are in equilibrium. This is the ideal location to park a communications satellite. The earth rotates at about 1,000 miles an hour, and because of their high earth orbit the geostationary satellites need to travel at about 7,000 mph to maintain position. This is just about the same speed as GPS satellites, but since they satellites are 10,000 miles further away they don?t move relative to the earth.

The GPS Control Segment is composed of Master Control Station, an Alternate Master Control Station, and a host of dedicated and shared Ground Antennas and Monitor Stations that work together to ensure the satellites are working to specification and the data they send to earth is accurate.

The GPS User Segment made up of of GPS receivers taking the shape of mobiles and , laptops, in-car navigation devices and hand-held tracking units along with the people that use them, and the software programs that make them function.

GPS receivers, no matter whether in a handset, or simply a spucific Gps tracking device, estimate position by accurately timing the signals passed on by GPS satellites. This information incorporates the moment the message was sent, specific orbital information (formally referred to as the ephemeris), along with the general system condition and approximated orbits of all GPS satellites (technically referred to as the almanac).

Another way of calculating device location is Triangulation or Mobile Location Services (MLS). Cell Tower Triangulation uses signal analysis data to compute the time it takes signals to travel from your smartphone to no less than 3 cell towers to calculate position.

With Mobile Location Services (MLS), the GSM cellular network provider uses triangulation techniques to try to pinpoint the position of the cell phone, its accuracy is proven to be less than than that of GPS. MLS is further affected by the same issues as GPS in the sense of the interference impeding signal strength and the density of GSM towers to help in the triangulation effort. In remote areas location accuracy may be off as much as a mile.

Much of the discussion surrounding cell tracking, mobile GPS and cell phone track software could be helped by a GPS Satellite primer.

GPS satellites broadcast signals from space that GPS receivers use to determine three-dimensional location (latitude, longitude, and altitude) plus precise time. GPS is an acronym for Global Positioning System and is a system that is composed of 3 primary segments: Space Segment, Control Segment and User Segment.

The GPS Space Segment incorporates twenty-four to thirty-two satellites that orbit the earth in medium earth orbit MEO. These satellites are referred to as the GPS Constellation, and they make an orbit once every 12 hours. They are not geostationary, they travel at over 7,000 mph. GPS satellites are solar powered but have battery backup for when they are in the earth?s shadow. They are placed so that at any given time there are at least 4 satellites ?visible? from any point on earth. Small rocket boosters on each satellite keep them flying in the correct path. The satellites have a lifetime of about 10 years until all their fuel runs out.

GPS Satellites are not communications satellites. Geostationary or communications satellites are at a much higher orbit of about 22,300 miles above the equator. These satellites are used for weather forecasting, satellite TV, satellite radio and most other types of global communications. At exactly 22,000 miles above the equator, the earth’s force of gravity and centrifugal forces are canceled and are in equilibrium. This is the ideal location to position a communications satellite. The earth rotates at about 1,000 miles an hour, and because of their high earth orbit the geo-synchronous satellites need to travel at about 7,000 mph to maintain position. This is just about the same speed as GPS satellites, but since stationary satellites are 10,000 miles further away they don?t move relative to the earth.

The GPS Control Segment made up of Master Control Station, an Alternate Master Control Station, and numerous dedicated and shared Ground Antennas and Monitor Stations that work together to make sure the satellites are functioning to specification and the information they send to earth is accurate.

The GPS User Segment consists of of GPS receivers taking the shape of mobile phones and , laptops, in-car navigation devices and hand-held tracking units along with the people that use them, and the software applications that make them function.

GPS receivers, whether or not inside of a handset, or simply a spucific Portable gps tracking system, compute specific location by precisely timing the signals transferred by GPS satellites. This information contains the time the message was transmitted, precise orbital details (technically referenced as the ephemeris), plus the general system condition and calculated orbits of all GPS satellites (formally called the almanac).

When satellite signals are not available, or accuracy and precision is less important than life of the battery, applying Cell-ID is a useful substitute to GPS cell phone location. The location of the mobile phone may be estimated by the cell network cell id, that recognizes the cell tower the cell phone is using. By having the position of this tower, you’ll be able to know approximately the spot where the mobile phone might be. Nonetheless, a tower can cover a huge area, from a couple of hundred meters, in high populationdensity regions, to several miles in lower density zones. For this reason location CellID accuracy is less than than GPS accuracy. Nonetheless tracking using CellID still presents a truly useful alternative.

Cell tracking, mobile GPS and mobile phone tracker software programs are unquestionably drawing attention from potential buyers, cell phone companies and software designers. The latest mobiles feature GPS position capabilities to track cell phone position.

GPS receivers, whether inside a handset, or simply a dedicated Portable gps tracking system, determine location by accurately timing the signals sent by GPS satellites. This information contains the moment the message was transmitted, accurate orbital information (technically referred to as the ephemeris), and also the general system condition and estimated orbits of all GPS satellites (formally referenced as the almanac). GPS receivers sometimes take a long time to become ready to use after being turned on because it must acquire some basic information in addition to finding GPS satellite signals. This delay is sometimes caused if the GPS device has been turned off for days or weeks, or has been transported a far distance while turned off for. The GPS must update its almanac and ephemeris data and store it in memory. The GPS almanac is a set of data that every GPS satellite transmits. When a GPS receiver has current almanac data in memory, it can acquire satellite signals and find initial position more quickly.

GPS Hot Start is the term for whenever the GPS enabled handset retains its last identified location, the satellites that were in range before, as well as the almanac data in memory, and makes an attempt to obtain the same satellites and compute a brand new position based upon the previous information. This is almost always the quickest GPS lock but Hot Start only works if the phone is in the same general area as when the GPS was last turned off. GPS Warm Start is the term for when the GPS enabled device remembers its last known location, and almanac used, but not which satellites were in range. It performs a reset and tries to lock onto satellite signals and computes a whole new location. The GPS receiver narrows the choice of which satellites tolook for since it kept its last known position and the almanac data helps determine which satellites are within view. The Warm Start is going to take longer than the Hot Start although not as long as a Cold Start. With GPS Cold Start, the device deletes all the previous information, and tries to locate satellites and complete a GPS lock. This normally takes the longest because there is no known reference information. The GPS enabled smartphone receiver must attempt to lock onto a satellite transmission from any available satellites.

So that you can get improved GPS lock times mobile phone manufacturers and system operators introduced Assisted GPS technology. This downloads the ephemeris and helps triangulate the handset general location. GPS Receivers will get a faster lock at the expense of a few kilobytes of data transmission. Assisted GPS, generally known as A-GPS or AGPS, improves the performance of normal GPS in mobile phones connected to the cell network. In America Sprint, Nextel, Verizon Wireless, and Alltel all use Assisted GPS. This is a means of utilizing the cellular network to speed up finding of GPS satellites.

A-GPS improves location tracking functions of smartphones (and also other connected devices) in two ways:

The first way is by helping to obtain a faster “time to first fix” (TTFF). Assisted GPS acquires and stores information in relation to satellite location using the cellular network and so the coordinates data does not need to be downloaded from the the satellite.

A subsequent approach is by assisting locate devices when GPS signals are weak or impeded. Due to the fact GPS satellite signals may be interfered with by tall buildings, and do not go through building interiors well AGPS utilizes proximity to cellular towers to estimate location when GPS signals are not accessible.

If satellite signals are not available, or precision is less important than battery life, making use of Cell-ID is a good substitute to GPS mobile phone tracking. The position of the mobile phone might be estimated by the cell network cell id, that identifies the cell tower the smartphone is connected to. By having the position of this tower, you may know roughly the spot where the handset is. Nonetheless, a tower can cover a large area, from a few hundred meters, in higher populationdensity locations, to several kilometers in lower density regions. For this reason location CellID accuracy is lower than GPS accuracy. Even so monitoring using CellID still supplies a very good substitute.

Another method of formulating mobile phone location is Triangulation or Mobile Location Services (MLS). Cell Tower Triangulation employs signal analysis data to compute the time it takes signals to travel from the phone to at least three cell towers to determine location.

Soon GPS will become almost as basic as the telephone, or more likely included with every cell phone. GPS can calculate locations accurate to a matter of just a few meters. In fact, amazingly with advanced forms of GPS it is possible to make measurements to less than a centimeter!

It’s just like assigning every square meter on the planet a unique address. GPS receivers have become extremely affordable as they have been miniaturized to just a few integrated circuits. These days GPS is becoming integrated into cars, boats, planes, construction equipment, movie making gear, farm machinery, laptop computers and especially smartphones.

Tracking cell phones is a active topic with a lot of interest. Much of the discussion dealing with cell tracking, mobile GPS and cell phone track software applications could be helped by a GPS Satellite primer and glossary.

GPS receivers compute location by precisely timing the signals sent by GPS satellites. This data includes the time the message was transmitted, precise orbital information (the ephemeris), and the general system health and rough orbits of all GPS satellites (the almanac).

Consider that there is a basic difference between mobile phone GPS Tracking and GPS Navigation. GPS cell phone tracking is typically associated with someone keeping records of either real-time or historical smartphone position, while Navigation deals with the handset user determining how to get from point A to point B. Neither use works without some sort of third-party software application.

Global Satellite System FAQ

Why does GPS receiver only work outside?

GPS satellites are orbiting such that from any point on earth there are a minimum four satellites visibile at any given time. Even though they use radio signals, the signal needs a clear of site to the receiver. If the GPS satellite slips below, or a building, or even heavy cloud cover, the radio signal may be lost.

What do the satellites do?

Each satellite is broadcasting the time. Both the satellite and the GPS receiver use atomic clocks for extreme accuracy. By measuring the difference between the time given by the satellite and the time in the GPS receiver, it can calculate the distance from the satellite.

How do GPS satellites know their location?

The satellites keep position archived inside in calculated tables. But satellites can deviate off course over time. To make adjustments, the satellite communicates with ground stations positioned around the globe. Whenever it connects with the ground stations, the satellite adjusts its internal location tables.

Does a GPS receiver send information back to the satellite?

No, they don’t do that. GPS equipped cell phones will send data but it isn’t going back to the satellite.

In the event that satellite signals are not readily available, or accuracy and precision is less important than battery life, employing Cell-ID is a viable alternative to GPS cell phone tracking. The location of the device might be computed by the cellular network cell id, that determines the cell tower the phone is using. By understanding the location of this tower, you may know roughly the location where the smartphone might be. Still, a tower can cover a huge area, from a few hundred meters, in high populationdensity regions, to several miles in lower density regions. This is why location CellID precision is lower than GPS accuracy. Nonetheless location via CellID still supplies a very useful substitute.

Mobile Phone GPS Tracking Basics

Throughout this discussion keep in mind that there is a basic difference between handset GPS Tracking and Navigation. GPS mobile phone tracking is normally associated with someone maintaining records of either real-time or historical smartphone location, while Navigation deals with the smartphone user determining how to get from point A to point B. Just because a cell phone has GPS doesn?t mean that it can necessarily be used as a navigation device. Just like cell tracking , navigation requires third-party software.

A lot of the discussion dealing with GPS tracking, mobile GPS and cell phone tracker software could be helped by a GPS Satellite primer.

GPS satellites broadcast signals from space that GPS receivers use to provide three-dimensional location (latitude, longitude, and altitude) plus precise time. GPS stands for Global Positioning System and is a network that is composed of 3 main segments: Space Segment, Control Segment and User Segment.

The GPS Space Segment consists of twenty-four to thirty-two satellites that orbit the earth in medium earth orbit MEO. These satellites are also known as as the GPS Constellation, and they are orbiting twice a day. They are not parked over one spot, but rather move at over 7,000 mph. They are solar powered but have battery reserve for when they are in the earth?s shadow. They are placed so that there are at least 4 satellites ?visible? from any point on earth. Small rocket boosters on each satellite keep them flying in the correct path. The satellites have a lifetime of about 10 years until all their fuel runs out.

GPS Satellites are not communications satellites. Geostationary or communications satellites are parked in space 22,300 miles above the equator. These satellites are used for weather forecasting, satellite TV, satellite radio and most other types of global communications. At exactly 22,000 miles above the equator, the earth’s force of gravity and centrifugal forces are offset and are in balance. This is the ideal location to position a stationary satellite. The earth rotates at about 1,000 miles an hour, and because of their high earth orbit the geo-synchronous satellites need to travel at about 7,000 mph to keep position. This is just about the same speed as GPS satellites, but since earth-synchronous satellites are 10,000 miles further away they don?t move relative to the earth.

The GPS Control Segment includes Master Control Station, an Alternate Master Control Station, and a host of dedicated and shared Ground Antennas and Monitor Stations that work together to make sure the satellites are working correctly and the information they send to earth is accurate.

The GPS User Segment incorporates of GPS receivers taking the shape of mobile phones and , laptops, in-car navigation devices and hand-held tracking units along with the people that use them, and the software applications that make them work.

GPS receivers calculate location by precisely timing the signals transmitted by GPS satellites. This information includes the time the message was transmitted, precise orbital information (the ephemeris), and the general system health and rough orbits of all GPS satellites (the almanac).

Another method of determining handset position is Triangulation or Mobile Location Services (MLS). Cell Tower Triangulation employs signal analysis data to compute the time it takes signals to travel from the smartphone to no less than 3 cell towers to judge position.

With Mobile Location Services (MLS), the GSM cellular network provider utilizes triangulation algorithms to calculate the position of the smartphone, its accuracy is proven to be much worse than that of GPS. MLS is further impacted by the same issues as GPS in the sense of the barriers affecting signal strength and the density of GSM towers to assist in the triangulation effort. In remote areas location accuracy may be off as much as a mile.
