MC-1722-B

LOCOSYS MC-1722-B is a complete standalone GNSS module. The module can simultaneously
acquire and track multiple satellite constellations that include GPS, BEIDOU, QZSS and SBAS. It features
low power and small form factor. Besides, it can provide you with superior sensitivity and performance even
in urban canyon and dense foliage environment.
This module supports hybrid ephemeris prediction to achieve faster cold start. One is self-generated
ephemeris prediction (called EASY) that is no need of both network assistance and host CPU’s intervention.
This is valid for up to 3 days and updates automatically from time to time when GNSS module is powered on
and satellites are available. The other is server-generated ephemeris prediction (called EPO) that gets from an
internet server. This is valid for up to 14 days. Both ephemeris predictions are stored in the on-board flash
memory and perform a cold start time less than 15 seconds.
