Lighthouse 2.0 Two Base Station Flight Instability
Posted: Mon Aug 30, 2021 12:50 am
Hi,
I have been using the Lighthouse Positioning System for a University Project and have had a few issues lately with the stability. When using a single Lighthouse 2.0 Base Station the accuracy and stability when flying Crazyflie 2.X drones appears to be as shown in the bitcraze videos. When adding a second base station however, I have encountered severe flight instability. I am aware the lighthouse beams occaisionally intersect and thus the drone has moments when the receiving indicators go red for both base stations however I believed that this would be negligible and the Crazyflie would be able to fly relatively well under its own onboard sensors until the momentary receiving loss ends.
I have double checked the channels of each base station, and all indicators appear to be green when checked within the Crazyflie Client before flying. Furthermore, the flight area contains no reflective items. I should mention I am using the latest firmware for the Crazyflies and decks as of this post alongside having a mix of 2.0 and 2.1 drones (However they both behave the same).
