GT-320RW
Fast Acquisition Enhanced Sensitivity 16 Channels GPS Sensor Module
The GT-320RW is a compact all-in-one GPS module solution intended for a broad range of Original Equipment Manufacturer (OEM) products, here fast and easy system integration and minimal development risk is required.
The module will continuously track all satellites in view and provide accurate satellite positioning data. The GT-320RW is optimized for applications requiring good 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 16 parallel channels and 4100 search bins provide fast satellite signal acquisition and short startup time. Its low power consumption is suitable for a wide range application in handhelds, sensors, asset tracking, PDA-centric personal navigation system, and vehicle navigation products.
Acquisition sensitivity of –140dBm and tracking sensitivity of –155dBm offer 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.
