How Can We Achieve Faster Cold Start Times in Automotive GPS Without Network Dependency?

The LS20030/31/32 series delivers cold start times under 15 seconds through hybrid ephemeris prediction—offering both self-generated 3-day prediction requiring zero network assistance and server-generated 14-day prediction. This dual-mode approach ensures your automotive navigation systems start quickly regardless of connectivity status, while the built-in 12 multi-tone interference canceller maintains reliable performance in urban environments. Contact us to integrate this proven MediaTek-based solution into your next-generation navigation systems.

Engineered for versatility, the LS20030/31/32 series offers three interface configurations—USB, UART, and RS232—to accommodate various integration requirements while maintaining low power consumption (13-22mA depending on model). The modules feature up to 10Hz update rates, built-in data logger functionality, and indoor/outdoor multi-path detection and compensation for enhanced accuracy. Operating across -40°C to 85°C temperature ranges with a compact 30x30x8mm form factor, these RoHS-compliant GPS smart antennas deliver fast time-to-first-fix and one-second navigation updates, making them ideal for automotive navigation, personal positioning devices, and marine navigation systems requiring superior sensitivity and reliable performance in demanding conditions.

LS20030 / 31 / 32 series products are complete GPS smart antenna receivers, including an embedded antenna and GPS receiver circuits, designed for a broad spectrum of OEM system applications. The product is based on the proven technology found in LOCOSYS 66 channel GPS SMD type receivers MC-1513 that use MediaTek chip solution. The GPS smart antenna 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.This module supports 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.
