We're using the M300RTK/P1 combination for mapping missions for bird population surveys.
The lower we can fly, the better the images, as long as we don't disturb the birds.
For several years we've used a Phantom 3 Pro at 30 to 35 meters, and it doesn't seem to bother anybody.
The Phantom 3, however, has the option for an "arched turn" from one grid path to the next. This flies in very quiet, smooth motion, cutting the corner in about 1 or 2 meters, never losing any speed.
The default turn for an M300RTK though is a sudden full stop, a jerk to the new heading, then another jerk to mission speed for the new leg. All of these motions also make a new, sudden sound.
All this erratic motion disturbs the birds, which means we have to fly higher and slower than we normally would.
I haven't been able to figure out how to make smooth turns yet, but I'm pretty sure all that stopping, starting, and jerking is also wasting battery capacity because it is a serious loss of energy and momentum.
I've worked out a system to fly mapping missions as a series of carefully spaced waypoints in "Mission Detailed KML" format that includes a planned home point to better estimate total flight time. It works well, but I sure would like to be able to smooth out those turns.
I tried multiple waypoint around each corner, but that doesn't work. The poor things just shudders around the corner.
In the mission KML file that you can export, it gives a "turn radius" with the default being something like "0.2", but selecting curved turns and changing that value doesn't seem to help.
Any suggestions appreciated |
