Navsync

GPS Module

The MS20 GPS module is a highly sensitive, compact single chip solution for GPS applications. It includes an RF receiver, complete baseband processor, Flash memory and a power control unit. The RF receiver uses a single conversion low-IF digital architecture, with the high-level integration leaving a few off-chip matching and decoupling components, minimizing system cost. The baseband processor is controlled by adaptive signal processing, and the navigation firmware is optimized for execution on a low power microprocessor.

Optimal signal acquisition and tracking strategy are enabled by sophisticated adaptive control algorithms. Sophisticated adaptive control algorithms provide optimal signal acquisition/tracking strategy.
