GENERAL DESCRIPTION

GM-820F GPS module is a highly sensitivity, ultra compact single chip for GPS application. It includes RF receiver, a fully-featured baseband processor, a Flash memory and a power management unit.

The RF receiver employs a single conversion digital low-IF architecture, the high level integration leaves only few off-chip matching and decoupling components really minimize the system cost.

The baseband processor is controlled by adaptive signal processing and navigation firmware optimized for execution on low power microprocessor. Sophisticated adaptive control algorithms provide optimal signal acquisition/tracking strategy.
