This is the ability of a GPS network to function optimally indoors and the server’s computation function for positions. GPS satellites usually send data that can be translated by the available receiver clearly in the sight of the satellite. The GPS constellation presently features a number of 28 satellites in orbit. To get all the live data, a receiver only has to sight all 28 satellites in orbit at the same time.
To do this, the cheapest and most efficient way would be to access a worldwide network having GPS reference stations. These GPS reference stations act as a data conduit to a server. This network can attend to any amount of A-GPS devices that may need it and from anywhere. Mokosmart has developed this network and implemented it.
What makes this network and server innovative are：It constitutes a completely redundant network having stations all over the globe. This is so that every GPS server is “seen” by a minimum of two different stations at any given time.
With this system, the server will need fewer satellite measurements to compute the position fully. This is done by a worldwide terrain model, which helps improve accuracy even with undulating terrain. It utilizes discrete points featuring grids numbering up to one billion that offer accuracy up to 18 meters in height.
The server does not need accurate GPS time tags to compute position because of GPS pseudorange measurements. It can also function on any device whatsoever, irrespective of the manufacturer.
