U-blox has released its tiny EVA-M8Q high-sensitivity GNSS module in a 7 millimeter by 7 millimeter package. EVA-M8Q supports GPS, GLONASS, BeiDou and Galileo, the company said in a news release. The EVA-M8Q completes the company’s lineup of receivers in the miniature and EVA form-factor package. The EVA-M8Q is TCXO-based and is optimized to provide the highest acquisition and tracking sensitivity, the company says, making it suitable for use with small antennas either in covert applications such as asset tracking and stolen vehicle recovery, or in portable devices; the previously announced EVA-M8M is better suited to cost-sensitive systems. “The key differentiator of the EVA-M8Q to the other cost effective EVA variants is the sensitivity,” says Stéphane Vincent, product strategy director, positioning, u-blox. “This, along with the accuracy provided by concurrent reception of three GNSS constellations, enables an end-system and its antennas to be easily hidden within a vehicle or other high-value asset that need to be tracked.” The ease of manufacturing offered by the Quad Flat No-leads (QFN)-like package suits requirements for medium- to high-volume production. While the highly integrated module of the EVA-M8 series allows OEMs to achieve a faster time-to-market. EVA-M8 series are the smallest u-blox modules featuring GPS, BeiDou, Galileo and GLONASS reception. Three out of the four GNSS constellations can be received concurrently, which leads to high positioning accuracy. The series also features anti-spoofing and anti-jamming technology to provide superior security and integrity protection. Samples of the EVA-M8Q are available now. The modules will be in full production in Q4 2016. Features Complete GNSS solution in 7 millimeter by 7 millimeter package. Sensitivity — ideal for small or covert installations. High accuracy from three concurrent GNSS. Highly integrated module leads to faster time-to-market. Anti-spoofing and anti-jamming.
