GPS, GLONASS, QZSS positioning module requires only an antenna

22 December 2013

Alpha Micro Components has introduced the smallest standalone GNSS positioning module on the market, the EVA-7M from u-blox.

Designed for high volume consumer and low- end commercial cost- and space-sensitive applications, this highly integrated 7 x 7 x 1.1mm LGA module comprises all necessary components, including crystal and passives. Users need only add an antenna for instant global positioning capability.

The module supports US GPS, Russian GLONASS, Japanese QZSS, plus all SBAS augmentation systems. Based on u-blox' advanced GNSS technology u-blox 7, the module achieves -160dBm sensitivity when tracking GPS satellites (-158dBm with GLONASS satellites), fast acquisition time and the lowest power of any u-blox 7 module (16.5mA at 3V) thanks to an innovative high-efficiency power converter.

The EVA-7M eases implementation in end-products because RF and digital domains are kept well separated, and the LGA pads are configured in single rows. EVA is a standalone receiver that provides a position without the need for host integration or extra RF components. It is optimised for keeping eBOM and system costs to an absolute minimum.

The module is suitable for consumer, industrial and after-market vehicle applications. First samples will be available in Q1 2014.
