http://www.satobs.org/position/IODformat.html COSPAR 4553: 53.3199N, 2.2438W, 86m (WGS84) ------------------------------------------------------------------ NOTES: ------ 1) The 99034 unknown was visible only in the corner of the image. It is in a 63.4 deg orbit. It may be that this is NOSS 3 (G) [11745/80019G] late by about 7.5 minutes and a bit off track due to its high drag. 2) The observations of USA 179 [28384/04034A] were made just before shadow entry at a range of about 13300 km. I used a new reduction routine in my software to obtain these points. By combining the timing information from the four frames and the predicted movement of the object across the sky, I can track the object in software. This essentially converts a trailed object into a point, hereby increasing the signal to noise. Since this is the first test of this software these observations should be treated with care. 3) The observations of USA 237 [38528/12034A] were obtained using the similar routine, but instead of tracking on the satellite, the software tracks the rate of the stars. With the camera staring at a fixed azimuth and elevation, this allows me to create two images; one without tracking, showing the geosynchronous satellite as a point, and one with tracking on the stars, showing the stars as points. This second image greatly facilitates the astrometric calibration because the image has fainter stars, and it works better on point like objects. This is also the first test of this approach, so please also treat these observations with care.
