In a GNC scheme (Guidance, Navigation and Control). The N(avigation) module feeds the G and the C.
It does not matter the supernice is your controller or guidance if your estimations are far from the actual values."

"By the way, will be the hardware schematics open source as well?"
"Congratulations Bill,
I still hope to have free time for continuing developing this kind of stuff. UKF is a great estimator indeed, I will check out the code for seeing your implementation :P."

"sure, I will contact you by mail"
"Hello Prindi,
about TRIAD, you can download the dcm_estimation.pdf. The implementation in Matlab is quite straightforward, you only have to type literally what is in the equations, there is not black magic.
Recently the Kalman Filter entry at…"

"getting started with a frame that lasts only one crash? xD"
"Yeah of course,
but if you are going to develop new navigation algorithms relying on raw data (served at fixed sample time), keep in mind that the results will be false.
Another issue to keep in mind (that happened to me). If you stress the HW to…"

"Hi Jean-Louis
I guess we are messing concepts here. By definition, for a HIL system in hard-real time dealing with fixed discrete time systems (like our autopilots), the host (X-Plane) shall guarantee this requirement throughout the simulation. But…"

"Just a tip for further works:
In my experience, X-Plane is not a "good" platform for testing avionics, this is not a real time software and it normally does not run in a hard-real time machine neither. You can not employ control techniques…"

"Hi Juan!
Well, as it is shown in your Figures, the IMU board only has one mount point, and this point is at the edge.
For an accelerometer the effect is the same like a diving board (…"

"You said that you had vibrations issues in the past... and you mount the IMU board like a "diving board"???"
"In my opinion, another point is the FPV itself.
Nowadays we are just few people but if in a near future we still growing, a "circulation code" have to be written. We are not bikes or cars, but we are not planes neither. I believe that something has…"

"Just one point about stadistics,
they say whatever we want, in the street, the probability of being hit by a foam plane is less than by a car. Just the same probability of being hit by a "spy bistec" (you know, cold, tough and with iron nerves),…"

"I believe Simon is right. We agree all that common sense is the best safety measure. So, pushing to the limits (it does not matter what kind of activity is) have to take place far from random people if this activity could be dangerous.
I agree with…"

Thanks for the info, I didn't know it. Actually here in Europe is how Hai Tran states. Any RC model can not be closer more than 30m to any civilian structure, and if it is a show or demonstration, "national guard" etc have to be present"
