Understanding some of the technical issues regarding Smartphone Spy Apps could be aided by a GPS Satellite primer. GPS satellites broadcast signals from space that GPS receivers utilize to figure out three-dimensional location (latitude, longitude, and altitude) plus accurate time. The acronym GPS signifies 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 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 power reserve when ever they may be on the dark side of the earth. They’re positioned so that at any given time there is at least 4 satellites visible from any point on earth. 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 are at a much higher orbit of about placed 22,300 miles above the equator. These kinds of satellites are used for weather forecasting, satellite TV, satellite radio and many other kinds of global communications. At precisely 22,000 miles above the equator, earth’s force of gravity and centrifugal forces are offset and are in balance. Here is the perfect location to park a communications satellite. The earth spins at about 1,000 miles per hour, and because of their high earth orbit the geo-synchronous satellites need to travel at about seven thousand mph to maintain position. This is approximately the same speed as GPS satellites, but because earth-synchronous 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 together to be sure the satellites are working correctly and the information they send out to earth is accurate.
The GPS User Segment made up of of GPS receivers represented by devices, laptops, in-car navigation devices and hand-held tracking gadgets together with the folks that use them, along with the software programs which make them work.
To help you trace a cell phone involves a number of principal ways of calculating mobile phone location. GPS (Global Positioning System/Satellites), Triangulation, and CellID. These technologies convert mobile phones into mobile monitoring devices. These kinds of systems can be seen as Network Based, Handset Based or possibly a Hybrid solution. GPS position is Handset based as it necessitates programs placed on the cell phone in conjunction with GPS hardware. Triangulation and CellID are Network Based because they use the equipment and information from the cellular provider. Hybrid systems bring together approaches to generate best use of available data and also to help make perform faster.
