Antenova recently released two new modules for GPS and GNSS. The M10578-A2 and M10578-A3 provide an easy drop-in receiver solution, which is a useful way to add location capability to very small consumer devices.
The modules—based on the MediaTek processor—both measure 9 × 9 × 1.8 mm with low current consumption, which makes them suitable for smaller portable devices, such as smart watches, navigation devices, OBD II modules, asset tracking, personal safety, and sports cameras.
The M10578-A2 module operates with GPS, with a 1-to-5-Hz update rate. The M10578-A3 operates with GPS, GLONASS, BEIDOU, and Gallileo with an update rate of 1 to 10 Hz. Included is internal self-generated orbit prediction that uses two GNSS systems simultaneously to give a faster time to fix and a second high-quality low noise amplifier (LNA) to boost low powered satellite signals. Both modules are pin compatible. As for the antenna function, Antenova offers the small Sinica SR4G008 GNSS antenna. Built on high-grade FR4 substrates with a high density, the modules’ multilayered design places the critical RF functions in the best position for location finding and performance.
