Spouse Tracking By Satellite – Background Details Pertaining To Mobile Phone Software Products For GPS Monitoring
A lot of the discussion surrounding keeping track of family members using GPS Tracking and phone location software used to convert a typical smartphone into a Spyphone might be helped with a GPS Satellite primer. GPS satellites broadcast signals from space that GPS receivers use to ascertain three-dimensional location (latitude, longitude, and altitude) plus accurate time. The acronym GPS signifies Global Positioning System and is a system which is made up of 3 main segments: Space Segment, Control Segment and User Segment.
The GPS Space Segment includes twenty-four to thirty-two satellites which orbit the globe in medium earth orbit MEO. These satellites are referred to as the GPS Constellation, and they are orbiting twice a day. They aren't geosynchronous, but rather move at over 7,000 mph. GPS satellites are solar powered but have battery power reserve when ever they are in the earth shadow. They are positioned so that at any given time one can find no less than 4 satellites visible from any point on the planet. Tiny rocket boosters on each satellite keep them correctly positioned. The satellites possess a lifetime of about a decade 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 types of satellites can be used for weather forecasting, satellite TV, satellite radio and many other kinds of global communications. At exactly 22,000 miles above the equator, earth's gravitational force and centrifugal forces are balanced out and therefore are in equilibrium. Here is the ideal 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 have to fly at about 7,000 mph to maintain position. This is approximately the same speed as GPS satellites, but due to the fact geostationary satellites are 10,000 miles further away they stay in place relative to the earth.
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 with each other to assure the satellites are working correctly and the information they send out to earth is correct.
The GPS User Segment consists of of GPS receivers taking the shape of devices, laptops, in-car navigation devices and hand-held tracking products and also the folks that use them, and the software programs that make them function.
