The GT-720F is a compact all-in-one GPS module solution intended for a broad range of Original Equipment Manufacturer (OEM) products, where fast and easy system integration and minimal development risk is required.

The receiver continuously tracks all satellites in view and provides accurate satellite positioning data. The GT-720F is optimized for applications requiring high-performance, low cost, and maximum flexibility; suitable for a wide range of OEM configurations including handhelds, sensors, asset tracking, PDA-centric personal navigation system, and vehicle navigation products.

Its 44 parallel channels and Venus520 search bins provide fast satellite signal acquisition and short startup time. Acquisition sensitivity of –155dBm and tracking sensitivity of –158dBm offers good navigation performance even in urban canyons having limited sky view.

Satellite-based augmentation systems, such as WAAS and EGNOS, are supported to yield improved accuracy.

Both the LVTTL-level and RS232-level serial interface are provided on the interface connector. Supply voltage of 3.8V~8.0V is supported.

Users can modify NMEA sentences or Binary code by the extra flash memory.
