Details about Mobile Phone Programs for GPS Tracking

Do you truly know where your Mobile Workforce or Kids are? – GPS Satellite Info Understanding a few of the details behind Smartphone Monitoring Products could be aided with a GPS Satellite primer. GPS satellites broadcast signals from space that GPS receivers use to pinpoint three-dimensional location (latitude, longitude, and altitude) plus precise time.

The acronym GPS stands for Global Positioning System and is a network which is comprised of 3 primary segments: Space Segment, Control Segment and User Segment. The GPS Space Segment includes twenty-four to thirty-two satellites which orbit the earth in medium earth orbit MEO. These types of satellites are referred to as the GPS Constellation, plus they are orbiting once every 12 hours. They aren’t geosynchronous, they travel at over 7,000 mph. They are solar powered but have battery power reserve for when they may be on the dark side of the earth. They are located so that one can find as a minimum 4 satellites visible from any point on earth. Tiny rocket boosters on each satellite keep them correctly positioned. The satellites have a duration of about ten years until all their fuel is exhausted. GPS Satellites are not communications satellites. Geostationary or communications satellites use a higher altitude placed 22,300 miles above the equator. These kinds of satellites can be used for weather forecasting, satellite TV, satellite radio and most other kinds 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. Here is the perfect place to park a communications satellite. The earth spins at about 1,000 miles per hour, and because of their high earth orbit the geostationary satellites have to travel at about 7,000 miles per hour to preserve 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 ground.

The GPS Control Segment includes Master Control Station, an Alternate Master Control Station, and numerous dedicated and shared Ground Antennas and Monitor Stations that work well with each other to ensure the satellites are working correctly and the info they beam down to earth is accurate. The GPS User Segment incorporates of GPS receivers represented by handsets, laptops, in-car navigation devices and hand-held tracking products and also the folks that make use of them, and also the software programs which make them operate.
