September 5th 1999

This page will hopefully show impartial comparisons between various images taken in the UK, from the same Noaa14 pass at 14:48 local time on 5th September 1999 using as many different systems as possible.

Please allow for local conditions i.e expected minimum elevations due to natural and man-made obstructions, also consider whether the aerials where directed, or more than one aerial was used via switching, also consider before making any decisions that most people would prefer to leave their systems to run on auto, and if a tracking system is deemed necessary for APT, then if so you may find HRPT within your reach.

Because of my 15 meg web space limit I will not use Thumbnails but if you click the text you can view the images.
