TDoA3 Long Range increases the distances that a Loco System can use when running in TDoA3, see the Loco Node documentation for more information.
The Crazyflie must run a special version of the firmware to use TDoA3 Long Range mode. The configuration is set using the kbuild menu and you should:
Expansion deck configuration/Support the Loco positioning deck
Expansion deck configuration/Algorithm to use/Use the Time Difference of Arrival (3) algorithm
Expansion deck configuration/Longer range mode
If you want to set configurations manually you should use:
CONFIG_DECK_LOCO=y CONFIG_DECK_LOCO_ALGORITHM_TDOA3=y CONFIG_DECK_LOCO_LONGER_RANGE=y
