u-blox LEA-M8T GNSS Timing Modules

u-blox LEA-M8T GNSS Timing Modules provide optimized accuracy and availability with survey-in and single-satellite timing. These GNSS timing modules feature minimized power consumption with low duty-cycle operation and maximized reliability with integrity monitoring and alarms. The LEA-M8T modules employ GNSS chips that are AEC-Q100 qualified, manufactured in ISO/TS 16949 certified sites, and thoroughly tested on a system level. These GNSS timing modules include a SAW filter and antenna power supervision and are ideal for use with active antennas or antenna signal distribution systems.

The LEA-M8T modules support GPS, BeiDou, GLONASS, and Galileo constellations and their enhanced sensitivity and concurrent constellation reception extent coverage and integrity to challenging signal environments. These GNSS timing modules include timing integrity measures with Receiver Autonomous Integrity Monitoring (RAIM) and continuous phase uncertainty estimation. The LEA-M8T modules feature high dynamic range radios with analog and digital interference mitigation, assisting applications in wireless communications equipment.
