Do you actually know just where your Staff or Family are? – GPS Satellite Discussion Getting a grasp on a few of the details regarding Mobile Monitoring Applications might be aided 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 exact time.

The acronym GPS stands for Global Positioning System and is a system which is comprised of 3 primary segments: Space Segment, Control Segment and User Segment. The GPS Space Segment consists of twenty-four to thirty-two satellites which orbit the earth in medium earth orbit MEO. These kinds of satellites are referred to as the GPS Constellation, and they make an orbit twice a day. They aren’t parked over one spot, but rather move at over 7,000 mph. GPS satellites are solar powered but have battery backup for when they may be in the earth shadow. They’re placed so that at any given time there can be at the very least four satellites visible from any point on the planet. Tiny rocket boosters on each satellite keep them correctly positioned. The satellites last about 10 years until all their fuel is exhausted. GPS Satellites are not communications satellites. Geostationary or communications satellites use a higher altitude located 22,300 miles above the equator. These 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 balanced out and are in equilibrium. This is actually the best place to spot a stationary satellite. The earth rotates at about 1,000 miles per hour, and because of their high earth orbit the geo-synchronous satellites need to fly at about 7,000 mph to sustain position. This is just about the same speed as GPS satellites, but given that communications satellites are 10,000 miles further away they don’t move relative to the ground.

The GPS Control Segment made up of Master Control Station, an Alternate Master Control Station, and quite a few dedicated and shared Ground Antennas and Monitor Stations that work well jointly to ensure the satellites are performing correctly and the info they send to earth is accurate. The GPS User Segment incorporates of GPS receivers taking the shape of devices, laptops, in-car navigation devices and hand-held tracking products combined with the people that make use of them, and also the software applications that make them operate.
