Hi all,
I use the DWM1000 to estimate the position of two beacons placed on a flying drone (they are acting as “tags” in the TWR scheme), using 4 ground beacons at fixed location (acting as “anchors” in the TWR scheme).
Sometimes when the drone is flying far away from the ground beacons, what we see is that the ranging with the first beacon still works, while the ranging with the next beacons are degraded or even impossible for the last one. And even when the drone comes back to close range, this situation keeps going.
Because the ground anchors are quite close to each other, I’m wondering if the first ground beacon, emitting its RESPONSE message to the drone’s tags, could cause the other beacons to lower their level of RX sensitivity (because they are receiving a strong signal) and therefore they can’t receive the next POLL messages from the drone tags (because they are too weak in comparison with the RESPONSE message of the first anchor). Do you think that is possible ? Or do you suggest other tracks to investigate ?
Any help would be much appreciated ! Thanks !
