GNS-2525F
GLONASS/GPS Modules
GNS-2525F module is a highly sensitivity, ultra compact GPS/GLONASS application. It includes MSR2112 RF receiver and a MSB2311 baseband processor comprises a full-featured GPS/GLONASS 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.
