Differences between GPS modules GPS02-UBX, GPS01-TD and GPS01
By sdga:NiceRF Wireless Technology Co., Ltd
GPS02-UBX is a new low-drift multi-satellite positioning and navigation GPS module based on UBLOX's latest generation IC M10 series. So what is the difference between it and our other two GPS modules GPS01-TD and GPS01?
Differences between GPS modules GPS02-UBX, GPS01-TD and GPS01
1. Similarities of the three GPS modules:
● With backup power input interface
● Support for hot start
● Support for power supply to active antenna
● Support A-GNSS assisted positioning
● Support for power-on reset, internallyintegrated low-voltage reset, external reset, software reset
● Operating temperature range: -40～85℃, storage temperature range: -40～125℃
● Positioning accuracy @ open field: level <3m, elevation <4.5m
● External antenna gain: 30dB
● Speed measurement accuracy <0.1m/s
● Time to first fix TTFF: cold start <28s, hot start: 1s, recapture: 1s
