A Short Introduction To Cell Phone GPS Tracking

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

GPS satellites broadcast signals from space that GPS receivers utilize to determine 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 includes 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, 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 at any given time 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 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 gravitational force and centrifugal forces are canceled and are in balance. This is the best 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 sustain position. This is just about the same speed as GPS satellites, but since geo-synchronous satellites are 10,000 miles further away they stay in place 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 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 cell phones 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 work.

GPS receivers sometimes take longer to become ready to navigate after it’s turned on because it must acquire some basic information in addition to capturing GPS satellite signals. This delay is sometimes caused if the GPS device has been turned off for days or weeks, or has been moved a significant 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 calculate initial location faster.

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

With Mobile Location Services (MLS), the GSM cellular network provider uses triangulation techniques to estimate the location of the mobile phone, its accuracy is proven to be less than than that of GPS. MLS is further impacted by factors similar to GPS in the sense of the interference affecting signal quality and the density of GSM towers to help in the triangulation effort. In remote areas position accuracy may be off as much as a mile.

Much of the discussion dealing with GPS tracking, mobile GPS and cell phone tracking 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 network that is made up of 3 main segments: Space Segment, Control Segment and User Segment.

The GPS Space Segment is comprised of twenty-four to thirty-two satellites that orbit the earth at a height of about 12,000 miles. These satellites are referred to as the GPS Constellation, and they make an orbit once every 12 hours. They are not geostationary, but rather move at over 7,000 mph. GPS satellites are solar powered but have battery reserve for when they are on the dark side of the earth. They are positioned 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 is exhausted.

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 gravitational force and centrifugal forces are canceled and are in equilibrium. This is the ideal location to place a stationary satellite. The earth rotates at about 1,000 miles an hour, and because of their high earth orbit the earth-synchronous satellites need to move at about 7,000 mph to sustain position. This is just about the same speed as GPS satellites, but since stationary satellites are 10,000 miles further away they stay in place relative to the earth.

The GPS Control Segment is comprised 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 correctly and the information they beam down to earth is accurate.

The GPS User Segment is composed of of GPS receivers taking the shape of smartphones 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 sometimes take longer to become ready to navigate after it’s turned on because it must acquire some basic information in addition to capturing GPS satellite signals.

When a GPS receiver has current almanac data in memory, it can capture signals and determine initial location faster.

If satellite signals are not accessible, 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 smartphone might be calculated by the cellular network cell id, that pinpoints the cell tower the smartphone is connected to. By knowing the position of this tower, you’ll be able to know roughly the spot where the cell phone might be. But, a tower can cover an enormous area, from a few hundred meters, in higher populationdensity locations, to a few miles in lower density regions. For this reason location CellID precision is lower than GPS accuracy. Having said that location using CellID still delivers a truly viable substitute.

A Short Introduction To Mobile Phone GPS Tracking

The Association between Short Message System (SMS) and Global System for Mobile Communications (GSM), and the Advancement Toward Multimedia Messaging Service (MMS)

Exchanging text messages, technically defined as Short Message System (SMS), but also acknowledged as “texting”, is a simple, easy, and convenient method to correspond to and from mobiles. Not just a very good method for people to correspond, SMS texting can be a practical way for software programs to exchange simple messages, and even setup commands, to and from smartphones. SMS texting doesn’t require a direct connection between smartphones; the communications infrastructure for the system is already in place, and it works across most mobile networks. One feature of SMS messaging that makes it especially valuable for mobile software programs is that it relies on mobile device fixed identity, the phone number. This facet gives a unique benefit over other technologies that use IP addresses because a mobile device IP address will vary depending on current network.

Short Message Service (SMS) is a communication service component of the GSM mobile communication system. It uses standardized communications rules that allow incoming and outgoing short text messages between cell phones. SMS text messaging is the most widely used data application in the world, boasting almost two and a half billion active users, or three quarters of all cellular phone subscribers.

SMS text messaging as used on modern smartphones was at first defined as part of the Global System for Mobile Communications (GSM) series of protocols in 1985 as a manner of transferring texts of up to 160 characters, between GSM mobile handsets. Since then service support has extended to comprise other mobile technologies such as ANSI CDMA networks and Digital AMPS, as well as satellite and landline networks. The majority of SMS messages are mobile-to-mobile text messages, though the standard supports other kinds of broadcast messaging as well. Computer to mobile SMS text messaging capabilities are also expanding rapidly.

GSM was initially called Groupe Spécial Mobile. It is the most popular standard for mobile telephone systems in the world. The GSM Association, the promoting trade organization of mobile phone network providers and manufacturers, estimates that approximately 80% of the global mobile market uses it. GSM is enjoyed by over 3 billion people across more than 212 countries and territories. Its ubiquity allows international roaming agreements between mobile phone network providers, offering subscribers the benefit of their cell phones in many parts of the world. GSM has evolved from its predecessor technologies in that both signaling and speech channels are digital. This means GSM is thought of as a second generation (2G) mobile phone system. This also facilitates the extensive implementation of data communication applications.

The pervasiveness of GSM implementation can be seen as a benefit for consumers that are given the ability to roam and switch carriers without needing to replace their mobile phones, and also to carriers, who can choose equipment from many equipment vendors. GSM pioneered affordable implementation of SMS texting, which subsequently has been supported on other mobile phone standards.

Newer versions of the standard are backward-compatible with the original GSM system. Release ’97 of the standard added packet data capabilities using General Packet Radio Service (GPRS). Release ’99 introduced higher speed data transmission by means of Enhanced Data Rates for GSM Evolution (EDGE).

General packet radio service (GPRS) is a packet oriented mobile data service available to users of the 2G and 3G GSM. In 2G systems. GPRS data communication is usually charged per megabyte of trafficsent and received, while data communication using traditional circuit switching is charged per minute of connection time, regardless of whether or not the subscriber actually is transmitting or if it is idle. GPRS is a best-effort packet switched service, as opposed to circuit switching, that has assured quality of service during the connection for non-mobile users.

2G cellular systems in combination with GPRS are frequently referred to as 2.5G. 2.5G is a technology bridge transitioning between the second (2G) and third (3G) generations of mobile telephony. It delivers moderate-speed data transfer, by using unused time division multiple access (TDMA) channels. Initially it was intended to extend GPRS to cover other standards, but these networks are converting to the GSM standard. GPRS is integrated into GSM Release 97 and newer releases.

GPRS was created as a GSM reaction to the earlier CDPD and i-mode packet switched cellular technology. Cellular Digital Packet Data (CDPD) was a wide-area mobile data service which used unused bandwidth normally used by AMPS mobile phones. It was discontinued in conjunction with the retirement of the parent AMPS service.

CDPD was developed in the early 1990′s, and was seen as a future technology. However, it had competition from then current slower but less expensive Mobitex and DataTac systems. CDPD never earned common acceptance and in time newer, faster standards such as GPRS earned widespread acceptance and started dominating.

For consumers CDPD had very limited offerings. AT&T Wireless initially sold the technology in the America under the brandname PocketNet, one of the very first consumer wireless web service products. Cingular Wireless later offered CDPD under the Wireless Internet brand (as opposed to Wireless Internet Express, Cingular Wireless GPRS/EDGE data). AT&T Wireless PocketNet was generally considered a failure. However, CDPD was used by some enterprise and government networks. It was especially popular as a first-generation wireless data solution for telemetry devices (machine to machine communications) and for public safety mobile data terminals.

Enhanced Data Rates for GSM Evolution (EDGE) (also referred to as Enhanced GPRS (EGPRS), or IMT Single Carrier (IMT-SC), and Enhanced Data Rates for Global Evolution) is a backward-compatible digital mobile phone technology that allows superior data transmission rates on top of standard GSM. EDGE is considered a 3G radio technology. EDGE allows more than three-fold boost in both the capacity and performance of GSM/GPRS networks by utilizing advanced techniques of coding and transmitting data, that deliver higher bit-rates per radio channel. EDGE delivers broadband performance and can be used for high bandwidth data applications such as Multimedia Messaging Service (MMS).

A very interesting software program that uses the connectivity between the mobile device and the internet to capture and archive MMS Multi-Media Messages, GPS location, SMS messages, and Call Event Logs is Phone Monitoring Software Mobile Monitoring.
