LS2003E-2RE

LS2003E-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.

This module supports self-generate orbit prediction, EASY™, to achieve faster cold start and warm start. The EASY™ is 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 regulars. Therefore, LS2003E-2RE of miniature size and brilliant performance is the best choice to be integrated into your slim devices.
