Hello people.

The main idea of my project is to find an optimal aiding technique from a variety of sensors, accurate INS/GPS integration, as source for feedback control in Unmanned Aerial Vehicles.

So, my questions are:

1- What are the actual parameters to evaluate a coupled INS/GNSS-system when used as source for feedback control?
- Data rate
- Noise level
- Transfer function, transfer delay
- Accuracy and precision
- …

2- Which sensors are definitely needed to control a small UAV?

3- What are the necessary conditions for the navigation system (accelerations, rates, speeds, flow angles, positions, velocities, update rate, total time delay) for feedback control in UAVs?

4- In the control system design process which are the variables to control? The UAVīs speed? Euler angles? Flow angles? Rates?...

5- What are exactly the specifications for those variables?

Thank you
