Fixed wing drones do work well with winds. They cruise at about 12 meters per second. They can fly for more than an hour. You get nice evenly timed photos with the survey pattern setup to fly across wind and always…"
"Event 38 has a fixed wing agricultural drone package. It doesn't support the payload weights you are after but it would allow you to prototype the system operation. I have found their fixed wing drones to be quite…"
"I managed to get a 3DR Solo with the Pixhawk 2 logging high data rate gyro data. The GYR1 data is logged at 1000Hz. It looks like the Pixhawk 2 has a low noise setup and gets full performance out of the…"
"@Anthonie That is the plan. I was going to compare the Pixhawk1 with the APM2.6. I may be able to compare the Pixhawk2 on the solo too. I am actually expecting things to be better on the battery. USB power is pretty…"
"I logged some data from a Pixhawk 1 and found that the rate noise is close to the the 0.005 deg/sec/root(Hz), single sided level in MPU6000 spec. A little higher than the spec., but I was bumping the desk at bit when I logged the data…"
"I just noticed that the Invensense ICM-20602 with its 0.004 deg/sec/root(Hz) is a single sided PSD measurement. This means that the ICM-20602 gyro angle random walk(ARW) is actually better than I showed in my early posts:
"APM 2.8 with the MPU6000 (0.005 deg/sec/root(Hz), 0.3 deg/root(hr)) is at least 2 times better than any of the HG1120s
Pixhawk 1 with its MPU6000 (0.005 deg/sec/root(Hz), 0.3 deg/root(hr)) is at least 2 times better than any of the HG1120s
"Comparing them in terms of angle random walk, the Invensense ICM-20602 0.004 deg/sec/root(Hz) is equivalent to 0.24 deg/root(hr). This is 2.5 times less rate noise than the best HG1120. The ICM-20602 is an excellent…"
"I have always liked the Iris. Even though I have a Solo now, I think the Iris is a better work quadcopter than the Solo. The Iris has both a primary rf control link and a secondary rf link for telemetry. …"
"Looked like you were close to getting it flying. Amazingly tough center section! Put the wings back on. It is worth another try.
I find that having an autopilot in aircraft(even if it is just manual flight…"
"For high stability you want the autopilot with the lower noise IMU gyros. The Pixhawk 1 with the lower noise MPU6000 IMU gyros is a better autopilot for hexacopter stability. The Pixhawk 1 uses the same processor…"
"That ICM20602 looks great. Both the ICM20600 and the ICM20602 have rate noise power spectral intensity of 0.004 deg/sec/root(Hz). This is slightly less noise than the MPU6000's 0.005 deg/sec/root(Hz) and much less than…"
"The Pixhawk2.1 is an well designed autopilot. Not sure why the lower performance IMU was used. Only one MPU9250 IMU is on the isolated IMU board. The ICM20600 IMU could have been used and it is slightly…"
"The Pixhawk1(2.4.x) uses the MPU6000 IMU, a redundant set of gyros(L3GD20 3-axis 16-bit gyroscope) and accelerometers(ST Micro LSM303D 3-axis 14-bit accelerometer / magnetometer). The MPU6000 IMU gyro noise(0.005 deg/sec/root(Hz)…"
