Technique
The plan is to simulate an extremely simple INS, using just one sensor, to calculate distance traveled after the fact. All we need is one single type of sensor, due to the errors in either accelerometers or gyroscopes being the same concepts.
A 3 axis accelerometer was taken, using software that records the measurements at approximately 50 hertz.
First, the distance between the bottom and top floors of Ross Hall, coming to approximately 11.6 meters.
We did a few trial runs to test that our software did work correctly, and that we could get navigation information from the measurements, manually calculated into movement far after taking the acceleration measurements.
Afterwards, we used an elevator as the most stable platform to test correctly on a large distance, without needing to factor in attitude changes. It was the best way to test out a single sensor at a time for individual errors.
