How Can We Achieve Reliable GPS Performance in Urban Environments for Automotive Navigation Systems?

The LS2003xU series delivers proven urban canyon performance through 66-channel MediaTek GPS technology with built-in 12 multi-tone active interference canceller and SBAS augmentation support. With hybrid ephemeris prediction achieving sub-15-second cold starts and multipath detection/compensation, this compact smart antenna ensures consistent positioning reliability for in-vehicle navigation. Contact our team to discuss integration options with USB, TTL, or RS232 interfaces tailored to your automotive system requirements.

Advanced hybrid ephemeris prediction technology enables cold start times under 15 seconds through both self-generated (3-day validity) and server-generated (14-day validity) predictions stored in onboard flash memory. The module features exceptionally low power consumption ranging from 26mA to 43mA depending on interface configuration, making it ideal for battery-powered applications. Additional capabilities include up to 10Hz update rate, built-in data logger functionality, ±11ns high-accuracy time pulse output (PPS), and LED indicators for GPS fix status. The wide operating temperature range of -40°C to 85°C, combined with indoor/outdoor multipath detection and compensation, ensures reliable performance across demanding automotive, personal positioning, and marine navigation applications requiring proven GPS receiver technology.

LS2003xU 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 receiver MC-1612 that uses 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.
