Designed with highest performance and smallest footprint in mind for wearable and IoT applications, the 7mm x 7mm Venus828F LGA module integrated all the necessary components forming a complete working GNSS receiver, including GNSS chipset, 0.5ppm TCXO, Flash memory, LDO regulator, DC/DC switching regulator, and passive components. It only requires external antenna and power supply to output accurate position / velocity / time information in standard NMEA-0183 format; enabling ease of use and fast time to market.

Venus828F features low power consumption, 29sec cold start TTFF, -165dBm tracking sensitivity, 10nsec 1PPS timing accuracy, on-board geo-fencing, 8Mbit ~ 512Mbit external SPI Flash data logging, and industrial operating temperature range of -40 ~ +85 degC. It has UART and I2C interface for flexible connection to the host processor.

Via SPI and I2C connection, data from MEMS sensor can be calculated by Venus828F using sensor hub enabled firmware, offloading computation from the host processor. Engineers can concentrate on their wearable and IoT applications instead of spending hundreds of hours reinventing the wheel developing sensor-fusion algorithms.

“Fast-acquisition high-sensitivity multi-GNSS chipset hardware are just becoming available in recent years, the internal firmware supporting multi-GNSS typically are not as fully optimized as GPS-only firmware that has matured for more than a decade to allow ROM codification with optimal performance for any existing GNSS chipset vendors; the multi-GNSS firmware is still being continuously improved over time,” said Michael Chung, VP of Sales & Marketing at SkyTraq.

“By offering Venus828F multi-GNSS receiver module with Flash memory, it’s shipped with latest highest performance firmware. It is also later upgradeable in the field if customer’s design allows. Targeting very high volume, cost-sensitive wearable and IoT applications, Venus828F is offered at price comparable to crystal-based ROM GPS modules on the market, setting a new benchmark in terms of performance, size, and cost for multi-GNSS receiver modules.”
