GPS-310FS Embedded GPS Module GPS-310FS Fast-Acquisition Enhanced-Sensitivity 16-Channel SMD GPS Receiver Module The GPS-31-FS is a miniature 16-channel OEM GPS receiver module. It is optimized for high-performance, ease-of-use, flexibility, and low-cost. The GPS receiver is suitable for a wide range of navigation and tracking applications. FEATURES 16 parallel channel GPS receiver 16 parallel channels and 4000+ correlators provide fast 4000+ correlators satellite signal acquisition and short start-up time. Acquisition SBAS (WAAS, EGNOS) support sensitivity of –140dBm and tracking sensitivity of –155dBm Supports active and passive antenna offers good performance even under difficult environments. High Sensitivity: -140dBm acquisition sensitivity The GPS-310FS provides one 3.3V UART serial I/O and one -155dBm tracking sensitivity GPIO pins. Self-contained LNA supports direct connection to Fast Acquisition: passive or active antenna. < 5 second hot start Sub-100mW power consumption makes the GPS-310FS < 35 seconds warm start ideal for battery-operated portable devices. < 60 second cold start Satellite-based augmentation systems, such as WAAS and 5m CEP accuracy Low Power Consumption, < 130mW Small Size, 25.4 x 25.4 x 3.4 mm EGNOS, are supported to yield improved accuracy. Small size and SMD mounting allow standard SMT assembly process, making it ideal for high volume production.
