  Re: Running VIO with GPS active

  Hi @Cliff-Wong ,

  Following up on your reply in the post "Running VIO w/ GPS Active". I am flying a Starling 2 and have been unable to conclude how Modal handles various sensor input streams to PX4.

  I see that the Starling 2 has a downward distance sensor, VIO, and GPS (in addition to IMU). This is where the confusion begins because I also see that default Starling PX4 parameters only have Vision enabled for heading, velocity, and position via EKF, that GPS is disabled & set to not exist, and that downward lidar sensor input is disabled.

  Does the VOXL perform some sort of sensor fusion on these input sources, then send the output of fusion to PX4 through the vision topic such that vision encompasses GPS, downward distance sensor, and VIO? Or is it the case that the sensor streams other than VIO are actually ignored by PX4 and/or not sent by default (in which case I can simply enable the sensor input and update EKF parameters).

  Could you provide more clarity and maybe any recommendation on how I could leverage the sensors in PX4?

  @QSL Hi, thank you for reaching out. There are many ways to achieve what you are trying. Starling 2 is the best starting point. You can then learn about what will work and what will not work and build out your system design from there.
