How Can Automotive OEMs Achieve Reliable Navigation in Urban Environments with Cost-Effective GNSS Solutions?

The MC-1612-B delivers urban canyon performance through MediaTek MT3333's 99-channel architecture with 12 multi-tone active interference canceller and multi-path detection. With IATF 16949 certification, SBAS support, and hybrid ephemeris prediction achieving sub-15 second cold starts, this compact module meets automotive-grade reliability requirements while reducing BOM costs. Contact us to receive detailed integration guides and automotive qualification test reports for your next-generation navigation systems.

Designed for mission-critical applications in automotive navigation, drone systems, marine equipment, and timing synchronization, the MC-1612-B features hybrid ephemeris prediction technology for faster cold starts—self-generated EASY prediction valid for 3 days and server-generated EPO prediction valid for 14 days, both achieving cold start times under 15 seconds. The module supports up to 10 Hz update rates with 10ns high-accuracy time pulse (1PPS) output, making it ideal for precision timing applications and 5G router devices. With IATF 16949 quality control certification, SMD mounting with stamp holes, RoHS compliance, and operation across -40°C to 85°C temperature range, the MC-1612-B delivers industrial-grade reliability for demanding automotive, drone, marine, and IoT tracking applications worldwide.

MC-1612-B

LOCOSYS MC-1612-B is a complete standalone GNSS module.
LOCOSYS MC-1612-B is a complete standalone GNSS module.

LOCOSYS MC-1612-B is based on MediaTek advanced new generation MT3333 GNSS chip. It is a complete standalone GNSS module which can simultaneously acquire and track multiple satellite constellations that include GPS, BEIDOU, GALILEO, 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.
