Before I do that, I print out those 50\r\norbits as text files and import them into a database. I can then\r\ncheck the dates or specific times that a certain satellite will be\r\nvisible.\r\n\r\nA simple way would be to estimate the precession rate from that\r\norbital data and do a back of the envelope calculation for when a bird\r\nwill be in a favourable position.\r\n\r\nOf course, one could always resort to looking up the necessary\r\nequations in an orbital mechanics text and do some number-crunching.\r\n\r\n73s\r\n\r\nBernhard VA6BMJ @ DO33FL\r\n_______________________________________________\r\nSent via [email protected].
