How to improve the GPS positioning on the receiver

First， you should judge the GPS drift caused by insufficient GPS sensitivity of the receiver or bugs in the RF algorithm. If it’s insufficient GPS sensitivity, you should find a better GPS antenna or GPS chipset. If it’s bugs in the RF algorithm, you should require the improvement on the GPS chipset from the manufacturer. Also, you can handle this improvement by smart processing in hardware firmware or software in a web-based GPS tracking platform.

First, if the vehicle is still, not moving anymore, you can hold the last GPS coordinate when it’s still moving. So even if the vehicle is beside high buildings or valleys, and the real GPS coordinates are running wildly, real-time data will not contain the real-time coordinates, but the old coordinates when generated at the last time when it’s still moving.
