The accuracy of GPS signal when the vehicles are still would be a little wild sometimes. The techniques may be a little old comparing to the Ublox GPS module nowadays. Globalsat and RoyalTek GPS modules are based on the Sirf Star III. Sirf III GPS the cost and performance are between Ublox and MTK GPS. If the vehicle comes out of tunnel, it may take some time to get the GPS signal. it has a little bad performance in GPS signal acquisition and stability. MTK GPS newcomer in GPS tracking business, and fast-growing. In the GPS tracking business, many manufacturers and designers use GPS modules as below: Ublox, Sirf Star III and MTK GPS.īelow are the comparisons between the three GPS chips based on our designing and manufadturing experience: Simple Comparison for GPS Modules: Ublox, Sirf III and MTK GPS
