Introduction
​
What is the project?
​
The project we developed by us is "Angle measurement system for three axis
gimbal nanosatellite testbench", and it is developed as a part of the course II1305 "Project in Information and Communication Technology".
​
Our project advisor is Nickolay Ivchenko (nickolay@kth.se), Space and Plasma Physics, EECS.
The objective of the project is to build a setup for measurement of the orientation of the gimbal testbench. The testbench is being developed as a part of an MSc thesis, to be used for testing the ADCS ( Attitude determination and control system ) of a free-flying payload, designed and built in the framework of the REXUS program ( Rocket EXperiments for University Students, see http://rexusbexus.net/ ). Having a system for recording the three rotation angles is critical both for the characterization of the testbench itself, as well as for the actual ADCS testing.
​
This involves working both with software and hardware.
​
One interesting aspect of finding the solution is that not only should it give the correct results, it must not disturb the gimbal itself - and this is quite tricky.
​
What are the main tasks?
​
-
Identifying different methods for measuring the angular position of three gimbal frames
-
Making a tradeoff between accuracy, sampling rate, complexity, level of disturbance to the gimbal, and cost.
-
Deciding on a viable solution
-
Finally: building and evaluating the system
