Global Positioning System

Faraday has been designed to use the Antennova M10478-2 GPS with a PCB footprint on the board. While you can connect other GPS units to Faraday via UART or SPI (we don’t provide the code) this is the simplest way. It just works.


  • Maximum VCC: 4.3V
  • Operating Temperature: -40C to +85C
  • Average Tracking Current: 24mA
  • Maximum Altitude: < 18 km
  • Maximum Speed: < 514 m/s


Location Awareness

Combining Faraday with a GPS allows location awareness. Faraday knowing it’s location on the Earth enables the small and smart radio node to open up new activities using amateur radio. APRS is the current big player in ham radio activities but we at FaradayRF believe there is a lot more we can do with knowing a location of the radio transmitters. This enables high accuracy timing (access to PPS signal on interrupt pin of Faraday) and GPS set clocks for remote nodes. Exciting!


Easy To Solder

If you are upgrading a Faraday which came without a GPS you’re in luck. We specifically chose the Antennova module in part because it was so easy to solder and comes with an on-board antenna. Everything in one package, hand solderable. Go explore.


Faraday at High Altitudes

We understand that the altitude and speed limits (ITAR imposed) are limiting in regards to high altitude ballooning. If you need high altitude operation above 18 km altitude (or care about it) then you will need to connect and support a different GPS module to Faraday via the UART connection for the GPS or external SPI. We flew a Faraday with balloons achieving great GPS performance even with the altitude limits. You can still fly Faraday with this GPS!
