How Can You Reduce Power Consumption and Size in Battery-Powered Handheld GPS Devices?

The LS2003D-G draws only 20mA with direct lithium battery connection and measures just 21 x 17 x 7.2mm—eliminating external RF connectors and cables. This integrated smart antenna solution reduces both your BOM costs and device footprint while achieving cold start under 15 seconds. Contact us to receive integration guidelines and power consumption profiles for your handheld design.

This smart antenna module eliminates the need for external RF connectors and coaxial cables, significantly reducing installation costs, system size, and time-to-market by removing R&D efforts on RF matching and stability issues. The integrated DC/DC converter optimizes power efficiency, while the built-in data logger and support for up to 10 Hz update rates make it ideal for personal positioning, automotive navigation, marine applications, and weather balloon tracking. With indoor and outdoor multi-path detection and compensation, RoHS compliance, and operating temperature range from -40°C to 85°C, the LS2003D-G represents the optimal choice for manufacturers seeking to integrate high-performance GNSS capabilities into slim, power-sensitive devices.

LS2003D-G

LS2003D-G is a complete standalone GNSS smart antenna module, including embedded patch antenna and GNSS receiver circuits.
LS2003D-G is a complete standalone GNSS smart antenna module, including embedded patch antenna and GNSS receiver circuits.

LS2003D-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, LS2003D-G of miniature size and brilliant performance is the best choice to be integrated into your slim devices.
