Smallest standalone GNSS chip
u-blox has introduced what it claims to be the smallest stand-alone GNSS receiver module ever.
The Swiss-based company's EVA-7M is a highly integrated GPS, GLONASS and QZSS positioning module requiring only an antenna.
Designed for cost- and space-sensitive applications, the integrated 7 x 7 x 1.1 mm land grid array (LGA) module comprises all necessary components, including crystal and passives - just requiring an antenna for global positioning capability.
The module supports GPS, GLONASS and the Japanese QZSS, plus all space-based augmentation systems (SBAS). It achieves -160 dBm sensitivity when tracking GPS satellites and -158 dBm with GLONASS, and claims fast acquisition time and a low power of 16.5 mA at 3 V.
u-blox stresses that this is a stand-alone GNSS receiver which provides position without the need for host integration or extra RF components - it is optimised for keeping the electronic bill of material (eBOM) and system costs to an absolute minimum.
The EVA-7M module is suitable for consumer, industrial and after-market vehicle applications. First samples will be available in Q1 2014.
