L76-LB module is a single receiver module integrated with GPS and BeiDou systems. It is able to achieve ,the industry’s highest level of sensitivity, accuracy and TTFF with the lowest power consumption in a
small lead-free package. The embedded flash memory provides capacity for storing user-specific,configurations and allows for future updates.
The module supports multiple positioning and navigation systems including autonomous GPS, BeiDou,SBAS (including WAAS, EGNOS, MSAS and GAGAN), QZSS and AGPS.Embedded with many advanced power saving modes including periodic, AlwaysLocateTM, standby and.backup, L76-LB module is of excellently low-power consumption in different scenes.
EASY technology as the key feature of L76-LB module is one kind of AGPS. Capable of collecting and,processing all internal aiding information like GPS time, ephemeris, last position, etc., the GNSS module,delivers a very short TTFF in either Hot or Warm start.
