    I have been using your Underwater GPS on the BlueROV2 (with 4 D1 receivers, 1 A1 analog locator, D1 master electronics board) for a few weeks now. It is fantastic!! I have it working reasonably well in an indoor swimming pool (20′ x 16′ x 4′).

    There seems to be an issue with the depth reading (See screenshot). We have a python script that streams the depth from a depth sensor in the BlueROV2 to the GPS (the driver was written by the Blue Robotics guys). The depth that I see in the QGroundControl doesn’t quite match what I see in the Acoustic tab on your web-based GUI (see image below). The depth seems to be fluctuating a lot more than it should.

    Great to hear that you are having success with the Underwater GPS!

    Are you using the 1.4 release?
    If so, we expect the input depth and output depth to differ.
    From the 1.4 release we will use the depth from the ROV as input and then adjust it based on acoustic triangulation.
    This typically improves the depth measurement, however in a very noisy environment the depth might fluctuate a bit.
