Hi Darwin Re your pole tracking mount. I dont know where the original idea came from but I seem to recall that you were possibly the first to try it from the amateur point of view. As you point out it is similar to the Baker-Nunn mounting and I do recall reading an article in a Russian publication ( translated to English!) describing the theory many years ago. Then I think Wilcox P.Overbeck based his prediction programs on a similar idea in the early 60's but there was no mechanical implementation of it or intention of such. I was very interested some years ago in making such a mounting and even elicited the assistance of Bjoern Gimle who wrote some software to use with such a system but like a lot of my bright schemes I never got around to building such a unit.(sorry Bjoern - -your labours may yet bear fruit!) As you know it is ideal as there is only one tracking movement whilst tracking and ideal for satellites passing through the zenith as there is no massive swing in azimuth. The disadvantage is that one ideally needs three stepper motors - one to set azimuth, the other to set on the pole of the satellite, and the other to actually track. The first two could be set manually but being lazy I would prefer to do it without moving from my chair. The first two motors could be simple DC motors but you would then need some encoding system to know where you are pointing . Another advantage is that the mount will have reduced vibration as only one setpper motor will be operating during the track. Maybe in my coming winter months Ill have a go at building such - its a lot simpler than a CoSaTrak system. Sorry I cannot be more positive about the origin of such a mounting. You have an interesting webpage .
