Yesterday we flew the Pelican in GPS mode, and after a few minutes of stable flight, all of a sudden it started going in a direction, even when i took my hands off the RC controller. So far, these signals were not used by the receivers as they were still labeled experimental. I am trying to see whether the GPS connector might be loose, but it’s difficult to know since I can’t reproduce this behaviour deterministically.
Connect your flight system as described above and click on “System Info” in the menu bar. The helicopter would go on height control mode then, which would explain the behavior. Some of my colleagues had this problem while doing some outdoor flight tests earlier this summer.
Yes, this is possible. Hello there, thanks a lot for v0 information about the unusual behavior in GPS mode. Google Maps is quite easy. Expand all Collapse all. You find it here: Search everywhere only autopillot this topic.
To fix this problem we maunal built a default firmware for asctc HL processor which reconfigures the GPS receiver, so that the problem is solved directly on-board the GPS unit. However, after analyzing the problem further we found out that the u-blox GPS receivers used on the AscTec Hummingbird and AscTec Pelican can get in trouble when using SBAS services, which have been cleared for regular operation earlier this year.
You can download it here. In reply to this post by kjackson. It is highly recommended to perform a motor controller update with the Research Upgrade Tool after all IDs have been assigned properly. That will include several new features and of course will fix manjal problem. The number is the serial number you were looking for. The window also displays further information, like your current software version of the low-level and high-level processor. From what I understand, GPS location can occasionally jump s of meters.
This device has not been authorized as required by the rules of the Federal Communications Commission. Skip to end of metadata. In this case, the safety pilot can always recover by switching to height controlled or manual mode, but we understand that this behavior needs to be prevented in the first place.
Does Pelican autopilot do any kind of flitering to mitigate this problem? Find the following lines: Motor Controller Update It is highly recommended to perform a motor controller update with the Research Upgrade Tool after all IDs have been assigned properly.
My question is, what kind of filtering if any is being done by autopilot, to smooth out the GPS signals. Now you need to georeference the image, therefore, we need the GPS position of the upper left corner and the lower right corner of the image.
Two weeks ago I broke two rotors crashlanding the Pelican to stop it from running away in a GPS mode. This aitopilot not work.
In the new “System Info” window click on “Update Information”. We will then inform you on our homepage about possibilities how to get the update. Identical behavior has been been observed here on multiple occasions. I don’t remember exactly what caused it, but it had to do with a GPS indexing issue, and required a firmware upgrade from AscTec.
In a panic, I had to then try to suddenly land the quad-rotor, which lead to a minor crash. Go back to Google Maps and click on the locations where the corners of your cropped image are. Manula line line in unedited main. In the event of unexpected behavior you can always use the RC ascrec take over control.
For this example we will name it “example. Open your favourite text editor and insert the following: Always take off and land manually.

Creating a Georeferenced Image Creating a georeferenced image aschec e. But one time it happened during the take-off one motor had reduced thrust. If autolilot UAV is new, this is our default connection and you do not need to change anything.
Using these services, in some situations the velocity measurements read from the GPS receiver, which are then used for the internal data fusion and position control, can be way off, which results in the vehicle shooting away.
