go back to all projects B-GSMGNSS SHIELD ENABLE ACTIVE GNSS ANTENNA HOWTO About this tutorial Find how to enable the active GNSS antenna powering circuitry for b-gsmgnss shields. Also, you may find the pads for 1PPS signal and raw GNSS UART TX. Platforms: ARDUINO, BEAGLEBONE, TEENSY, RASPBERRY PI or other 2.8V-5V micro-controller or SBC. Time needed: maximum 5 minutes. Previous skills required: Soldering. b-gsmgnss shield enable powering for GNSS active antenna In the image up-here, notice: a. The "jumper GNSS antenna power selector" solder jumper. To enable the powering for active GNSS antennas, just solder over the two pads of this jumper [close the powering circuit]. b. 1PPS signal [output, 2.8V] and RAW GNSS TX port [output, 2.8V] having 115200bps, 8,N,1. HINTS: 1. Always double check what you've done, before powering. 2. You may use GPS only antenna, but the GLONASS satellites will be seen with not so good/proper signal/noise ratio [the GLONASS bandwidth is different from GPS one]. In 99% of the cases this crack will work for you. Anyway, we recommend combo GPS+GLONASS antenna usage. TUTORIAL PROVIDED WITHOUT ANY WARRANTY!!! USE IT AT YOUR OWN RISK!!!!
