This GPS receiver is designed to provide high precision timing and positioning for FM Single Frequency Network transmitters. It delivers reliable NMEA data and an accurate one pulse per second signal, enabling precise time alignment between geographically distributed transmitters.
The NMEA output supplies standard GNSS positioning, time, and status information for system monitoring and configuration. The 1PPS output provides a highly stable and low jitter timing reference synchronized to UTC, ensuring phase accurate synchronization required for SFN operation. This minimizes self interference and helps maintain optimal network performance.
The receiver is engineered for broadcast and telecommunications environments and offers fast satellite acquisition, robust signal tracking, and stable operation under varying environmental conditions. It is suitable for integration into FM transmitters, exciters, and synchronization controllers where dependable timing accuracy is critical.
Key benefits include precise UTC referenced 1PPS for SFN timing synchronization, standard NMEA output for positioning and system diagnostics, reliable continuous operation, and easy integration into broadcast transmission systems.
