Details about Phone Programs for GPS Monitoring – GPS Satellite Discussion Understanding a few of the details regarding Cellphone Spy Applications might be assisted by a GPS Satellite guide. GPS satellites broadcast signals from space that GPS receivers work with to identify three-dimensional location (latitude, longitude, and altitude) plus exact time.
The acronym GPS represents Global Positioning System and is a network which is composed of 3 primary 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 also known as as the GPS Constellation, plus they are orbiting once every 12 hours. They are not parked over one spot, they travel at over 7,000 mph. GPS satellites are solar powered but have battery backup when ever they are in the earth shadow. They are located so that at any given time one can find at the least four satellites visible from any point on earth. Small rocket boosters on each satellite keep them flying in the correct path. 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 found 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 precisely 22,000 miles above the equator, earth’s gravitational force and centrifugal forces are balanced out and they are in balance. Here is the best position to park a stationary satellite. The earth spins at about 1,000 miles per hour, and because of their high earth orbit the earth-synchronous satellites have to travel at about 7,000 miles per hour to sustain position. This is approximately the same velocity as GPS satellites, but given that geostationary satellites are 10,000 miles further away they stay in place relative to the ground.
The GPS Control Segment consists of Master Control Station, an Alternate Master Control Station, and many dedicated and shared Ground Antennas and Monitor Stations that work well collectively to ensure the satellites are functioning correctly and the data they deliver to earth is correct. The GPS User Segment is composed of of GPS receivers represented by smartphones, laptops, in-car navigation devices and hand-held tracking products and also the people that make use of them, and the software applications that make them operate.
