One of the most common reasons that the controller will emit a continuous beeping sound is due to a low battery. This beeping sound is not an alert of an issue that needs to be resolved, so there’s no action required to fix it. The exact tone or pattern of the start-up and shut-down chime sequence will depend upon the drone model. These beeping sounds are not continuous or incessant, and can more accurately be described as a chime.

Just to make sure there’s no confusion on this point, the controller will generally make a series of beeping sounds when it is initially turned on, and then again when it is turned off.

In most cases, the beeping is an alert signaling an issue that needs to be fixed, so we’ll also look at how to resolve the issues behind the beeping. Let’s look in-depth at the most common causes of a continual beeping sound coming from your controller.

To resolve these issues, check your battery charge level, calibrate your controller, or perform a firmware update or rollback. In general, the most common reasons for a continual beeping sound coming from your controller is due to a low battery, joystick misalignment, or a firmware issue. So how can you figure out what the beeping means, and resolve the issue behind it? The last thing you want is to ignore an alert, in case that might end up in an unfortunate malfunction of the drone, causing a crash or damage to the drone. The “EKF Status” has changed to “good”, meaning the vehicle is ready to fly in GPS modes.Things seem to be going along well with learning the ins and outs of this whole drone thing when suddenly the remote controller starts up a constant beeping sound. Note that at the time this image was captured the speed accuracy was above 1.0, but it had been below 1.0 for 10 seconds, so the EKF was able to start tracking position and velocity. The above image shows what you get when the GPS is finally good enough. A really good speed accuracy is 0.3 or less. Note that while the Speed Accuracy is below 1.0, it is still not good. The Speed Accuracy is good enough (it is below 1.0), but the position accuracy is too high (it is over 9 meters) and the height accuracy is also bad (at over 8 meters).

The above shows an example where it has 8 satellites but is not yet good enough for GPS flight. For GPS to be good enough for flight it needs to meet the following conditions continuously for 10 seconds: While the above shows 3D lock, it is not yet good enough for ArduPilot to use the GPS to fly in a GPS flight mode. In the above case the drone was in a position with poor view of the sky (it was on a verandah, with many trees above it). The Fix time shows how long it took to get 3D lock.

The Speed Accuracy is now much lower, but not yet below the critical threshold of 1.0.

This means the GPS is still not good enough

FixType is 3 or larger, meaning it has 3D lock (it may be 4 if the GPS can see a SBAS satellite).

Once the GPS gets 3D lock then you will get status like this: The app will do this for you in a future version, or the web interface will do it on the status page. You can manually copy the file from to the UBLOX directory on your microSD. It should look like this in Īs shown in the image, the filename for the MGA data on the microSD card is UBLOX\OFFLINE.UBX If you are seeing a zero MGA Cache Size then check it is downloading correctly to the microSD. That file is needed to allow for faster GPS lock.

If the MGA Cache Size is zero then please check if you can download the above OFFLINE.UBX file.

Time Source: this is where the GPS got its estimate of the time from (2 means from the web browser).

Pos Source: this is where the GPS got its estimate of position from (2 means from the web browser).

The size of this cache should match the current file at

MGA Cache Size: the MGA cache is the downloaded file that gives the satellite orbits.Latitude/Longitude: the current lat/lon where it is searching.EKF Status: “bad” means the GPS is not yet able to be used.

NumSats: the number of satellites found.

FixType 1: that means it has found a GPS (there is a GPS attached), but it doesn’t yet have GPS lock.

The above image shows what happens when the SkyViper is searching for GPS lock. Start off by opening the web interface, and looking at the GPS tab of the status page: If you have poor GPS performance then please follow the guide below to help diagnose the cause. The GPS tab in the status page is useful to show you progress towards GPS lock as well as information regarding the MGA data cache. It is automatically pulled down to the Sky Viper Video Viewer app when connecting to the internet and will update once connected to the drone if the current data is out of date. The fastest GPS Lock is achieved by having up to date MGA UBLOX assistance data. If your Sky Viper does not perform as expected, there are a few things to try.
