Please tell us a bit about your UAV interest
I'm doing research for package delivery with UAV. UAV are my work and my hobby.

"@Hugues, We are only using Septentrio RTK for the moment but we are also working on a visual sensor.
@Darrell, If it fits in our schedule we are definitely joining the Outback Challenge :-). "

"@Alexey: Did you changed the EKF default parameter values while you were testing with the RTK GPS? "
"Indeed, the gps device from Septentrio. It's linked to the pixhawk by a serial connection.
Configuration in Missionplanner:
- gps driver : SBF
- correction data is send to the TCP port by datalink (software provided by Septentrio) and linked to…"

Lately, a lot of companies have commercialized their own RTK GPS receiver. On this blog I will provide information about accurate landings based on an AsteRX-m UAS receiver which works on L1 and L2 frequency.I’ve tested landings with an f450 DJI…
"Hi Olivier,
It's plug and play, of course you have to select the correct driver (SBF) for the GPS and to land accurate you will have to tune your vehicle. You also have to.configure the Kalmanfilter because the measurements from the GPS are very…"

Hi all,We are testing the RTK GPS receiver from Septentrio, the AsteRX-m UAS with ArduCopter 3.4. The GPS can be used to land accurate as shown in the first part of our video. The land location was logged and loaded into the waypoint file in Mission…
"What was the speed and turn rate you were flying with? We are flying against the speed limit, if you set an unrealistic high turn rate (for example 20 deg/s), wp_speed at 2000 cm/s, wp acceleration at 500cm/s² the copter will try to go as fast as…"
"That's possible, but I think if the copter can't reach the rate you set as parameter, the arducopter code uses the rate that is calculated from the actual velocity of the vehicle and the radius of the circle. "
While flying several circles with different radius (in Auto_mode with the command loiter_turns) my vehicle starts losing altitude when it has a speed of 10 m/s. The first idea was that this was caused by the aerodynamic effect that causes the…
"Michael, like Jesus A. said the rover costs around 5K. I don't have experience with using a normal Survey Grade GPS as base station. We don't use a local base station. We use NTRIP, in Belgium different reference stations are spread and they send…"
"Indeed, I adapted the ArduCopter3.3 code to make use from the GPS altitude. When the GPS status switches from 3D Fix to 3D Fix RTK I use the heigth measurements from the GPS instead of those from the barometer."
"Hi Michael,
We use NTRIP as base station: RTCM messages are sended to my laptop by using internet and a telemetry module sends these messages to the rover.
It is possible to set up a local base station, septentrio has these but they are expensive…"

"We did an auto mission with the Septentrio asterx-m (https://www.youtube.com/watch?v=XrEAQV0pXUo). The landing accuracy is 10 - 20cm. The EKF makes also use from the altitude of the gps when switching from 3D fix to 3D fix RTK. It works on…"
"I also implemented the RTK GPS (AsteRx-m UAS) from Septentrio, for my thesis at KULeuven. I did an autonomous mission with it. The result is on youtube. https://www.youtube.com/watch?v=XrEAQV0pXUo"
"No it happens also when I connect the battery. The first error I always get is preArm: rangefinder check, normally you have to lift your vehicle 50cm above the ground because the autopilot needs to check if the sonar is of good quality. If I do this…"
I'm using an I2C splitter to connect more sensors on my pixhawk. When I only connect my external compass to the I2C splitter Mission Planner gives no error. When I connect my optical flow sensor, sonar and external compass I get the error compass…
