Ultra-compact & low cost GPS, GLONASS, BeiDou, QZSS module

November 07, 2014 // By Graham Prophet
Swiss-based u-blox’ EVA-M8M is a stand-alone positioning module; bringing concurrent multi-GNSS performance into the ultra-compact EVA footprint, EVA-M8M is claimed as the smallest commercially available GNSS module.

Designed for cost and space sensitive applications, the highly integrated 7 x 7 x 1.1 mm LGA module comprises all necessary components, including crystal and passives. EVA-M8M requires only an external antenna to provide an accurate position without the need for host integration. Components have been selected for reliable operation in the field over the full operating temperature range. The module is also compatible with the EVA-7M GPS module for upgrading of existing designs at minimal cost.

The module supports US GPS, Russian GLONASS, Chinese BeiDou, Japanese QZSS, plus SBAS augmentation systems. Based on u-blox M8 performance, the module achieves -164 dBm tracking sensitivity, fast acquisition time and low power consumption. EVA-M8M can track any two GNSS systems simultaneously and output a GNSS position up to 18 Hz.

UART, USB, SPI and I²C interfaces provide flexible connections to a host processor. EVA-M8M can also communicate directly with u-blox' SARA 2G, LISA 3G and TOBY 4G cellular modules to support advanced tracking and location-aware products. For existing designs using a NEO module, the C88-M8M adaptor board can be used for evaluation of the EVA-M8M in existing NEO-xM designs.
