Does the BigQuad deck allows RTK gps system?

[estrategico]

We are thinking in outdoor position systems with high accuracy for swarm projects, Does the BigQuad deck allows RTK gps system?
Is there another alternative in outdoor Positioning systems?

There is currently no RTK support implemented in the Crazyflie firmware. Though, the bigquad deck has a bidirectional UART connection which would allow to support it in firmware. I have never used RTK system so I am not sure how this would be implemented in details but if it is needed, you could push RTK data to the Crazyflies using Crazyradio. There is support for sending broadcast packet that should be well suited for this.
