""one of the reasons that the Pixhawk autopilot has been so successful has been the remarkably low noise level of the MPU6000s." ... Well probably actually because the software/hardware is adequate to do the job and is…"
"Tom, One of the key parameters for an inertial navigation measurement unit for a navigation system like the Pixhawk, that is assisted with a GPS, is the angle random walk level of the gyros. The HG1120s are not that…"
"I am approaching 3 years on my first Techpod. It is amazing how many hours of flight time you can build up on a Techpod. Typically I get about 2.5 hours of flight time at 13 m/s airspeed using two 6600 mAhr 4s…"
"I think that the 5v power supply on the standard 3DR power module will generate 5.3 volts down to a battery voltage of 6 volts or so. I have only tested this myself accidentally by drawing the batteries down to 7 volts in the…"
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:
