There seem to be a handful of UWB systems that may be applicable for drone usage. I’m left wondering whether they are all more-or-less equivalent, or if some of these perform better than others.
My goal is to simultaneously localize up to 100 drones, all within roughly a 50 x 50 m area and with a max altitude of 50 m.
Two systems I’m considering are Pozyx (looks to be Ardupilot-ready: https://ardupilot.org/copter/docs/common-pozyx.html) and Ciholas. Then there is the DWM1000 module itself that might be used directly (the same chip is used by both Pozyx and Ciholas).
Does anyone have experience with using these systems and can comment on the pros/cons? Am I crazy to even consider using UWB over GPS-RTK? The UWB tags seem cheaper, but they would need some number of anchors positioned around the flying area.
