How Can You Reduce GPS Cold Start Time for Better User Experience in Vehicle Navigation Systems?

The LS2303x GPS mouse achieves cold start times under 15 seconds using hybrid ephemeris prediction technology—self-generated (3-day validity) and server-generated (14-day validity) stored in on-board flash memory. With 66-channel acquisition, SBAS support, and built-in interference cancellation, your automotive navigation systems gain faster satellite lock and superior urban canyon performance. Contact us to integrate proven GPS mouse technology that enhances driver satisfaction and reduces time-to-navigation.

Advanced hybrid ephemeris prediction technology sets the LS2303x apart from conventional GPS receivers. The module supports both self-generated ephemeris prediction (valid for 3 days without network assistance) and server-generated prediction (valid for 14 days), both stored in on-board flash memory to achieve cold start times under 15 seconds. With support for SBAS (WAAS, EGNOS, MSAS) and Japan's QZSS, plus features like indoor/outdoor multi-path detection and compensation, LED positioning status indicators, waterproof construction, and magnetic mounting, the LS2303x delivers professional-grade navigation performance. Update rates up to 10 Hz make it suitable for high-quality NTP time servers and precision timing applications, while the built-in micro battery preserves system data for rapid satellite reacquisition.

LS2303x series products are complete GPS receivers (also known as GPS mouse) based on the proven technology found in LOCOSYS 66 channel GPS SMD type receivers MC-1612 that use MediaTek chip solution.
LS2303x series products are complete GPS receivers (also known as GPS mouse) based on the proven technology found in LOCOSYS 66 channel GPS SMD type receivers MC-1612 that use MediaTek chip solution.

LS2303x series products are complete GPS receivers (also known as GPS mouse) based on the proven technology found in LOCOSYS 66 channel GPS SMD type receivers MC-1612 that use MediaTek chip solution. The GPS mouse will acquire up to 66 satellites at a time while providing fast Time-To-First-Fix, one-second navigation update and low power consumption. It can provide you with superior sensitivity and performance even in urban canyon and dense foliage environment. Its far-reaching capability meets the sensitivity requirements of car navigation as well as other location-based applications.
These products support hybrid ephemeris prediction to achieve faster cold start. One is self-generated ephemeris prediction 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 GPS module is powered on and satellites are available. The other is server-generated ephemeris prediction 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.
