How Can You Reduce GPS Module Integration Costs While Minimizing Device Size?

The LS2003C eliminates RF connectors and coaxial cables through its integrated patch antenna design, reducing both component costs and PCB space requirements. With SMT-capable installation and direct lithium battery connection via built-in DC/DC converter, you can accelerate time-to-market while achieving ultra-compact 15.5x15.5x6.6mm form factor. Contact us to receive integration guidelines and sample units for your next-generation handheld GPS device.

Engineered for simplified integration, the LS2003C eliminates the need for RF connectors and coaxial cables required by separated GPS active antennas, reducing both cost and design complexity while accelerating time-to-market. The SMT process-capable design with built-in DC/DC converter allows direct connection to lithium batteries without external voltage regulators, making it ideal for battery-powered handheld devices, automotive navigation systems, marine applications, and weather balloon radiosondes. Additional features include up to 10Hz update rate, ±11ns high-accuracy time pulse (1PPS), built-in data logger, indoor/outdoor multi-path detection and compensation, and RoHS compliance. This combination of miniature size, brilliant performance, and easy installation makes the LS2003C the optimal choice for slim device integration across personal positioning, automotive, and marine navigation markets.

LS2003C

LS2003C is a complete standalone GPS smart antenna module, including embedded patch antenna and GPS receiver circuits.
LS2003C is a complete standalone GPS smart antenna module, including embedded patch antenna and GPS receiver circuits.

LS2003C is a complete standalone GPS smart antenna module, including embedded patch antenna and GPS receiver circuits. The module's functionality is using MediaTek All-in-One GPS chip, MT3339, and it acquires 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 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 GPS 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 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, LS2003C of miniature size and brilliant performance is the best choice to be integrated into your slim devices.
