GPS-330R GPS Receiver Module GPS-330R (USB Interface) Fast Acquisition Enhanced Sensitivity 16 Channel GPS Sensor Module FEATURES 16 parallel channel GPS receiver 4100 simultaneous time-frequency search bins SBAS (WAAS, EGNOS) support High Sensitivity: -140dBm acquisition sensitivity -155dBm tracking sensitivity Fast Acquisition: < 5 second hot start < 35 seconds warm start < 60 second cold start 5m CEP accuracy The GPS-330R 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 GPS-330R 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. Acquisition sensitivity of –140dBm and tracking sensitivity of –155dBm 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. USB-level serial interface is provided on the interface connector. Supply voltage of 3.8V~8.0V is supported.
