How Can You Reduce Integration Costs and Accelerate Time-to-Market for Handheld GPS Devices?

The LS2003E-G eliminates RF connectors and coaxial cables through its integrated smart antenna design, cutting both component costs and R&D efforts on RF matching. With its ultra-compact 22x22mm footprint and direct lithium battery connection, you can integrate positioning functionality into slim handheld devices faster while reducing assembly complexity. Contact us to receive integration guidelines and samples that demonstrate how our standalone solution can streamline your product development cycle.

Featuring hybrid ephemeris prediction technology, the LS2003E-G achieves cold start times under 15 seconds through both self-generated EASY (valid for 3 days) and server-generated EPO (valid for 14 days) predictions stored in onboard flash memory. This standalone design eliminates the need for RF connectors and coaxial cables, reducing integration costs and accelerating time-to-market by removing R&D efforts on RF matching between separate antenna and module components. With up to 10Hz update rate, ±11ns high-accuracy time pulse (1PPS), built-in data logger, and advanced indoor/outdoor multi-path detection and compensation, the LS2003E-G is the optimal choice for personal positioning devices, automotive navigation systems, marine applications, and weather balloon tracking where miniature size, brilliant performance, and easy installation are critical requirements.

LS2003E-G

LS2003E-G is a complete standalone GNSS smart antenna module, including embedded patch antenna and GNSS receiver circuits.
LS2003E-G is a complete standalone GNSS smart antenna module, including embedded patch antenna and GNSS receiver circuits.

LS2003E-G is a complete standalone GNSS smart antenna module, including embedded patch antenna and GNSS receiver circuits. The module can simultaneously acquire and track multiple satellite constellations that include GPS, GLONASS, 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.

It is easy to install without both RF connector and coaxial cable that are needed in a separated GNSS active antenna. In other words, reduce the cost and size. Also, speed up the time to market by eliminating R&D efforts on RF matching and stability between separated GNSS antenna and module. Furthermore, it can be directly powered by a lithium battery without any external voltage regulars. Therefore, LS2003E-G of miniature size and brilliant performance is the best choice to be integrated into your slim devices.
