NAVSIGHTHM.1.4
2.3.6. Internal GNSS (Trimble, HW revision < 1.5)
The NAVSIGHT-T embed a high end, survey grade, dual antenna, Trimble GNSS receiver that is perfectly
fitted for the very demanding survey market.
It features L1/L2/L5 and L-Band signals tracking and uses GPS, GLONASS, BEIDOU and GALILEO
constellations to provide very accurate and reliable measurements even in harsh environments.
The internal L-Band demodulator supports OmniSTAR and Marinestar Precise Point Positioning (PPP)
services to delivery world wide, with no specific infrastructure, a positioning accuracy better than 10 cm.
This high performance GNSS receiver also features very accurate RTK positioning. This receiver provides
excellent accuracy and reliability in harsh GNSS environments.
