"ArduCopter (on Iris) and Phantom 4 were the best. Alsmost ideal flight precision. PX4 (on the same Iris) was good but ArduCopter still better. My congratulations to the ardupilot team and contributors - it's marvelous that open source autopilot…"

"I'm impressed by this series and would love to see a summary in table form when you're done. Right now, if memory serves, it's: APM, PX4, DJI Phantom 4: pretty much perfect Microkopter, Microdrone, Lockheed Martin, earlier DJI (such…"

"Pretty good result as expected, and I notice it wasn't a wind-free day either.Would be interesting to see the results if you set a 1 second delay on each waypoint, it could cause the craft to exactly hit each corner and stop, making truly…"

Comparing Precision of Autopilots for Survey Missions - Pixhawk with ArduCopter firmware

Hi, We have reached the long-awaited episode in our autopilot precision series in which we finally test Pixhawk. All drones are tested by flying them on a simple photogrammetry route created in UgCS mission planning software. In this video Pixhawk was mounted on 3DR IRIS platform, the same one used in our PX4 test. Pixhawk was…See More

"@Yang Wang: apparently you can connect to the camera via USB RNDIS (virtual ethernet) and then get raw h.264 frames via UDT on 192.168.1.3 port 9000Looks like making sense of the CAN bus gimbal and camera controls is the bigger problem."

Delay time between consecutive shots in survey missions

Hi, guys,Recently one of our customers discovered an interesting fact while doing a photogrammetry survey using DJI A2 autopilot system - if the time between consecutive photos was set at less than 2.1 seconds, not all of the photos were taken. Despite the camera used guaranteeing a minimum time between consecutive photos as 0.9 seconds, there seems to exist a certain lag time within the Flight Controller that extends this minimum time between consecutive shots.After doing the tests with time…See More
