GPS-41SMD
Fast-Acquisition Enhanced-Sensitivity 12-Channel SMD GPS Receiver Module
The GPS-41SMD is a miniature 12-channel OEM GPS
FEATURES
12 parallel channel GPS receiver 4000+ correlators SBAS (WAAS, EGNOS) support Supports active and passive antenna High Sensitivity: -137dBm acquisition sensitivity -147dBm tracking sensitivity Fast Acquisition: < 5 second hot start < 50 second cold start 5m CEP accuracy Low Power Consumption, < 100mW Small Size, 22.4 x 17.0 x 3.3 mm
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. 12 parallel channels and 4000+ correlators provide fast satellite signal acquisition and short start-up time. Acquisition sensitivity of -137dBm and tracking sensitivity of -147dBm offers good performance even under difficult environments. The GPS-41SMD provides one 3.3V UART serial I/O and one GPIO pins. Self-contained LNA supports direct connection to passive or active antenna. Sub-100mW power consumption makes the GPS-41SMD ideal for battery-operated portable devices. Satellite-based augmentation systems, such as WAAS and EGNOS, are supported to yield improved accuracy. Small size and SMD mounting allow standard SMT assembly process, making it ideal for high volume production.

1PPS Output
The GPS receiver is in navigation mode upon power-up, with 1PPS output free running. After 3 minutes of valid position fix and remaining under static-mode, the receiver changes to timing-mode, with 1PPS output signal synchronized to the UTC second. The receiver will change to navigation-mode, with 1PPS output free running, if the receiver is in motion. The 1PPS output will become synchronized to the UTC second again after the receiver had remained in static mode for 3 minutes.
