Write a filter for a dataset of GPS locations

Job Description:

Some of the GPS trackers (namely the TR06 and GT06E models by Concox) we use have a firmware bug which causes very strange positions to be sent to our server. Essentially the GPS hardware will sometimes transmit the same device timestamp with 2 different coordinates, sometimes make the vehicle jump backwards, even tho the vehicle is traveling on a road and going forward.

Unfortunately, we are not able to fix the firmware of the device so we will have to develop a filter script in php which scans our db for these specific devices and then reads through the locations and based on a filter logic determines the error records and deletes them.

Please only bid for this project if you have previous experience with GPS data processing. Suitable bidders will be issued database access for a demo set of data as it comes in from the hardware.

Skills: PHP, MySQL, GPS, A-GPS
