1 Accuracy and TTFF may be affected by atmospheric conditions, signal multipath, satellite geometry, and corrections availability and quality.
2 Assumes minimum of five satellites per product manual procedures. High multi-path, high PDOP, or severe atmospheric conditions may degrade performance.
3 Long baselines, long occupations, precise ephemeris used.
4 At very low temperatures UHF module should not be used in transmitter mode.
5 Without batteries. Batteries can be stored up to +70 °C.
6 Network RTK PPM values referenced to the closest physical base station.
7 Receiver initialization time varies based on GNSS constellation health, multipath level, and proximity to obstructions.
