How Can We Reduce Power Consumption in Battery-Powered Automotive GPS Devices?

The LS2003D-2RE delivers industry-leading ultra-low 17mA power consumption with built-in DC/DC converter, allowing direct lithium battery connection (3.0V-4.3V) without external regulators. This standalone solution extends battery life significantly while maintaining 66-channel GPS tracking and fast TTFF performance—ideal for automotive aftermarket devices and portable navigation systems. Contact us to discover how our power-efficient GPS smart antenna can reduce your device's energy footprint and operational costs.

The LS2003D-2RE features EASY self-generate orbit prediction technology that achieves faster cold start and warm start without requiring network assistance or host CPU intervention. The prediction remains valid for up to 3 days and updates automatically when satellites are available. This standalone design eliminates the need for RF connectors and coaxial cables, reducing both cost and size while accelerating time-to-market by removing R&D efforts on RF matching and stability. With fast TTFF at low signal levels, up to 10 Hz update rate, ±11ns high accuracy time pulse (1PPS), and indoor/outdoor multi-path detection and compensation, the LS2003D-2RE is the ideal GPS solution for automotive navigation, handheld devices, marine navigation, and personal positioning applications requiring miniature size and brilliant performance.

LS2003D-2RE

LS2003D-2RE is a complete standalone GPS smart antenna module, including embedded patch antenna and GPS receiver circuits.
LS2003D-2RE is a complete standalone GPS smart antenna module, including embedded patch antenna and GPS receiver circuits.

LS2003D-2RE is a complete standalone GPS smart antenna module, including embedded patch antenna and GPS receiver circuits. The module's functionality is using MediaTek lateast GPS, MT3337E, ROM chip and it can
acquire a lot of satellites at a time while providing fast time-to-first-fix and low power consumption. Besides,
it can provide you with superior sensitivity and performance even in urban canyon and dense foliage
environment.
The new module supports self-generate orbit prediction, called EASYTM, to achieve faster cold start
and warm start. The EASYTMis no need of both network assistance and host CPU’s intervention. The
prediction is valid for up to 3 days and updates automatically from time to time when GPS module is powered
on and satellites are available.
It is easy to install without both RF connector and coaxial cable that are needed in a separated GPS
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 GPS antenna and module. Furthermore, it can be
directly powered by a lithium battery without any external voltage regulators. Therefore, LS2003D-2RE of
miniature size and brilliant performance is the best choice to be integrated into your slim devices.
