Antenova, a manufacturer of antennas and RF antenna modules for M2M and the Internet of Things, has released two new modules for GPS and GNSS. Both provide a drop-in receiver solution - a neat way to add a location capability to very small consumer devices. The modules are based on the popular MediaTek processor.

The two modules are similar, both measuring 9.0x9.0x1.8mm, with low current consumption, making them suitable for smaller portable devices, such as smart watches, navigation devices, OBD II modules, asset tracking, personal safety, sports cameras and equipment.

There are two part numbers. The M10578-A2 module operates with GPS, with a 1-5Hz update rate, and the M10578-A3 operates with GPS, GLONASS, BEIDOU and Gallileo with an update rate of 1-10Hz.

Antenova has added two features to enhance performance of the modules. There is an internal self generated orbit prediction which uses two GNSS systems simultaneously to give a faster time to fix, and a second high quality LNA (low noise amplifier) to boost low powered satellite signals.

The M10578 modules are the latest in Antenova’s RADIONOVA series of RF modules for wireless M2M and embedded devices. Both modules are pin compatible, offering integration and upgrade from GPS to GNSS, and for the antenna function, Antenova offers the small Sinica SR4G008 GNSS antenna.

The modules are built on high grade FR4 substrates with a high density, multi-layered design that places the critical RF functions in the best position for location finding and performance.
