POSITION OF MOVING PLATFORM USING G.P.S. SATELLITE SIGNALSMethod and apparatus are disclosed for accurately deter- mining position from GPS satellites (12, 13, 14) and received on a ship (10) using the following observable signals: C/A code group delay observable tau ; 308 f0 implicit ...
A GPS signal, including GPS time and Doppler, is received from a pseudolite positioned on the Earth and an approximate position of each of a plurality of second GPS satellites is determined from an onboard almanac. Side lobe signals and accompanying noise are received from antennas on the ...

and then transmit them through HackRF, which becomes a pseudo base station. Moreover, one device can transmit multiple signals simultaneously, simulating multiple satellites.

Also, GPS only works when a sufficient number of satellites are in “view,” which prevents it from working indoors, and makes it more difficult when surrounded by tall buildings or trees. Again, tracking can be improved by combining technologies. GPS can be combined with SLAM techniques to ...
The algorithm has been designed and tested using a simulated model with uncertainties associated with the GPS clocks and station clocks. For measurement simulation, the GPS almanac containing orbital information of the GPS satellites and a set of 8 ground stations were employed. At each step of ...
