RTK Mission Setup


Setting up an RTK GPS mission is easy and very similar to a standard mission. The two distinct differences are setting up the base station and waiting for the right GPS fix solution.

Follow these steps to prepare an RTK GPS mission.

  • Assemble the antennas onto the radios.

WARNING - Never power the radios with the antenna detached. Doing so could damage the RF signal chain and degrade performance.

  • Assemble the base station onto the tripod, place with a large open view of the sky, and turn it on. Do not move the base stations once it starts surveying its location.
  • Power on the drone and let the SLANTRANGE system perform standard system checks.
  • Once all the checks are complete, the AIS red, yellow, and green LEDs will start blinking. As the RTK system calculates the location solution, the LEDs will turn solid.
    • Red solid - Base station has finished survey and is transmitting RCTM messages. GPS solution has achieved a DGNSS fix type.
    • Yellow solid - GPS solution has achieved a RTK FLOAT fix type with an estimated position accuracy of less than 0.05 meters.
    • Green solid - GPS solution has achieved a RTK FIXED fix type with an estimated position accuracy of less than 0.02 meters.
  • Once all the LEDS are solid, toggle the AIS button to initiate capturing data.

    Note: Although it is not necessary, it is strongly recommended to wait for a solid green LED before starting image capture. If it is taking more than 5 minutes for a RTK FIXED solution, a solid yellow LED is sufficient.

  • Wait for the blinking green LED signaling active data collection and begin the mission.
