How Can We Reduce GPS Integration Costs While Maintaining High Performance in Automotive Navigation Systems?

The LS2003C-2RE eliminates RF connectors and coaxial cables through its integrated smart antenna design, reducing both component costs and assembly complexity. With built-in DC/DC converter allowing direct lithium battery connection and SMT-capable installation, you can accelerate time-to-market while cutting R&D expenses on RF matching. Contact us to discover how this MediaTek-based solution delivers 66-channel GPS tracking with fast TTFF at a fraction of traditional integration costs.

Designed for easy integration through SMT process capability, this GPS smart antenna eliminates the need for RF connectors and coaxial cables required in separated GPS active antennas, significantly reducing cost, size, and time-to-market while eliminating R&D efforts on RF matching and stability. The module supports up to 10 Hz update rate and features a built-in 12 multi-tone active interference canceller for robust performance, ±11ns high accuracy time pulse (1PPS) with NMEA synchronization, and indoor/outdoor multi-path detection and compensation. Operating reliably across -40°C to 85°C temperature range and meeting RoHS compliance standards, the LS2003C-2RE is the optimal solution for automotive navigation, handheld positioning devices, marine navigation systems, and aftermarket applications requiring high-performance GPS functionality in a miniature form factor.

LS2003C-2RE

LS2003C-2RE is a complete standalone GPS smart antenna module, including embedded patch antenna and GPS receiver circuits.
LS2003C-2RE is a complete standalone GPS smart antenna module, including embedded patch antenna and GPS receiver circuits.

LS2003C-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, EASYTM, to achieve faster cold start and warm start. The EASYTM 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 regulators. Therefore, LS2003C-2RE of miniature size and brilliant performance is the best choice to be integrated into your slim devices.
