GlobalTop Technology has launched FireFly X1, said to be one of the smallest multi-GNSS (global navigation satellite system) modules in the world at just 9,0 x 9,5 x 2,1 mm. Utilising the latest Mediatek MT3333 engine, it provides full support for GPS, QZSS, Glonass and Beidou, and is also Galileo ready.
Tracking of up to two constellations simultaneously, and relying on the latest Mediatek rmware, the device can provide positioning accuracy down to 1,8 m CEP. Enabling EASY (self-generated orbit prediction), AGPS (ephermis le injection) and SBAS further enhances position accuracy significantly.
Despite its diminutive size, FireFly X1 incorporates a complete set of high-quality components, including TCXO, RTC crystal, SMPS, SAW filter and an additional LNA to provide reliable performance. It also provides multi-interface connectivity options like SPI and I²C, and is ideal for M2M devices relying on low-cost microcontrollers that offer limited serial interfaces.
GlobalTop’s free customisation service further expands the capability of FireFly X1 with unique features such as custom NMEA output sentence, distance calculation, geofencing, magnetic variation, last-position retention and others. Advanced users can also customise the basic parameters of the module, including baud rate, update rate, internal logger settings, DGPS mode, 3D fix, 1 pps timing, and many more.
