GNSS positioning module achieves -160dBm sensitivity

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 -160 dBm sensitivity when tracking GPS satellites (-158 dBm with GLONASS satellites), fast acquisition time and the lowest power of any u-blox 7 module (16.5 mA at 3 V) thanks to an innovative high-efficiency power converter.

The module eases implementation in end-products because RF and digital domains are kept well separated, and the LGA pads are configured in single rows. Unlike other GNSS receivers on the market, EVA is a standalone receiver which 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 EVA-7M brings embedded satellite positioning to the next level of portability,” said Thomas Nigg, VP Product Marketing at u-blox.  “The module has been developed with ease-of-manufacturing as a high priority. Its QFN-like footprint with connections along four sides and a high-level of component integration makes it a perfect solution for medium and high volume production runs. This ensures high first-pass production yield, crucial criteria especially for cost-sensitive, high-volume industrial and consumer applications."

Christos Papakyriacou, Managing Director, Alpha Micro, added, “Cost effective and compact modules for high volume consumer and low- end commercial applications have long been a focus for Alpha Micro. We are delighted to add the EVA-7M to our product portfolio.  The EVA-7M, the industry’s smallest standalone GNSS module, offers end users one of the lowest system cost in the industry, minimal power consumption, simple integration with u-blox wireless modules and eases design and manufacturing. No host integration or external components are needed. A UART, USB, SPI and I2C interfaces provide flexible connections to a host processor. It can also communicate directly with u-blox' SARA 2G, LISA 3G and TOBY LTE cellular modules to support advanced tracking and location-aware applications.  A welcome addition to our comprehensive product range.”

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