Talk:Satellite watching

Article life
After reading an article about the falling dead spy satellite, I noticed that wikipedia has nothing about satellite watchers/satellite trackers/satellite spotters whatsoever, unlike bird watching or even train spotting. Laudak (talk) 19:15, 14 February 2008 (UTC)

IOD
I found a source for the IOD Observation Format Description, the detailed description of the skywatcher sat observation format of sats and satellite passes. This seems to be the format that most of the SeeSat satellite observations are in. The format is described here, and includes this bit:

Positional observations of satellites provide the basis to determine their orbits, and to study their optical characteristics. The latter provide the basis for the accurate brightness predictions that we have come to expect from our favourite prediction software or service. Positional observations are analysed using computer programs, so observers need a systematic and accurate reporting format, ideally one that can be read by both humans and machines. The IOD (Interactive Orbit Determination) format is one of several that meet this need.

George D. Lewis developed the IOD observation format, and a supporting data-entry program, called ObsEntry
