To show speed in the app, I either could get it from the gps provider or compute it myself. I was reading on the net and came across an article which said that, "not all gps providers give speed". I could have made my life simple by assuming that the gps provider will give speed. But I thought that it would be a good exercise to actually compute the speed.
I came across a page which said that kalman filters are used to compute this. It is because of the stochastic nature of the algorithm that it uses all the data provided to it and uses it to compute the best value. With the positions provided by the gp@ containing significant errors, I had to do something. Kalman filters look like the ideal way for me right now. I just finished an introductory level reading about the kalman filters.
I have two more holidays left in this extended weekend to make use of my time. This is the best time for me to concentrate on his completely and come up with a fine solution.
