Indoor navigation using WIFI signal strength trilateration.

Hi,i am currently looking at ways to implement a wifi based navigation system using an arduino uno in combination with a wifi shield. The shield is able to detect wifi signal strength and could possibly be used to reconstruct the position of an arducopter indoors using trilateration. The environment would typically be mapped in advance to provide a reference. Or in a more basic setting in a scheme where distance is measured by first determining four corners in a square. I am wondering if this…See More

"Kate, you can run the data you have now through the system identification toolbox but my guess is that the results will be questionable. Especially if you try data from a flight. the toolbox assumes a fixed sample rate and assumes that the sample…"

Who is using the Arducopter for education

Hi All,As i teacher i found the Arducopter ideal for use in an college/university level course on system integration signal processing and measurement & control. In this course 5-10 students are using a single kit over a period of 5-6 weeks. We have about 3-5 groups a year. In the first year we achieved indoor flight in combination with the construction of an intelligent payload with a camera and a manipulator.We are considering an expansion of the measurement and control component of the…See More

LORAN-C

I was wondering if there are known cases of amateur UAV's which have LORAN-C navigation rather than GPS or in combination with GPS. Thanks for any info, i am interested in accuracy, bandwidth, computational complexity and last but not least, indoor or urban (between buildings) performance. Jan van Hulzen See More
