[amsat-bb] Re: How to add Moon Keps to SatPC32
Hi Laurent, Attention: The Moon TLE (2line) it's not usefull for the SGP4/8 two lines format ephemerid model (InstantTrack, SatPC32 etc. ) the format is only a compress readable parameters The moon: Giving Keplerian elements for the moon is much more difficult. The main problem is that the moon's orbital plane has a fixed inclination with reference to the ecliptic plane. The moon's orbital plane wobbles around there and turns once every 18.6 years. Seen from the earth, that gives an changing inclination of about 18 to 28 degrees. The inclination of true earth satellites, on the other hand, remains fixed and the tracking program assumes that the inclination is not changing. The only way to overcome that problem is to give sets of Keplerian elements every 50 to 100 days. In that period the change of the inclination is not too big and the error stays small. A second problem with Keplerian elements for the moon is that the moon's orbit is severely perturbed in a way a ordinary satellite tracking program cannot handle. Those perturbations come from the sun, the earth (not being a exact sphere) and from major planets. To compute those perturbations exactly, we would need several hundred corrective terms. For the accuracy needed here (1-3 degrees for the usual amateur satellite antenna), it has been sufficient to correct only for the varying eccentricity. 73, de Michael ___ Sent via amsat...@amsat.org.

Don't specifically know for SatPC32, but Pseudo keps for the moon that seem to work in any tracking program are available on LogSat's web site. http://www.logsat.com/lsp.asp Right at the bottom of the page. I use LogSat 5.2 for tracking, its a great piece of software! ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

It's a stand alone program that already has the information for the sun and the moon!

If you are using KEPS such as below MOON 1 0U 0A 10019.90529622 . 0-0 0-0 0 0004 2 0 25.1631 348.5977 0637000 142.8591 221.8486 00.0366009966 They don't work in SatPC32 12.8 until your change the Sat number on both lines to something greater than 0 So, for example, the following will work MOON 1 1U 0A 10019.90529622 . 0-0 0-0 0 0004 2 1 25.1631 348.5977 0637000 142.8591 221.8486 00.0366009966 Tested under Win 7 Starter on EeePC Netbook.
