SkyTraq Technology’s Venus828F is a new standalone multi-GNSS receiver module in a small 7 x 7 mm form factor. It works with multiple satellite systems and tracks up to 28 satellites concurrently.
Designed with wearable and Internet-of-Things (IoT) applications in mind, the LGA module integrates all the necessary components for a working receiver, including GNSS chipset, 0,5 ppm TCXO, Flash memory, LDO regulator, DC-DC switching regulator and passive components. It requires only an external antenna and power supply to output accurate position/velocity/time information in standard NMEA-0183 format.
Venus828F features low power consumption, 29 second cold start time-to-first-fix, -165 dBm tracking sensitivity, 10 ns 1PPS timing accuracy, onboard geo-fencing, 8 – 512 Mbit external SPI Flash data logging, and industrial operating temperature range of -40°C to +85°C. It can interface to a host processor via UART or I²C.
Data from a MEMS sensor can be calculated by the module using sensor hub enabled firmware, offloading computation from the host processor. This allows engineers to concentrate on their wearable and IoT applications instead of spending hundreds of hours developing sensor fusion algorithms.
