[amsat-bb] Re: AO40 WISP MA error!

[Mineo Wakita <ei7m-wkt@xxxxxxxxxxxxxxx>]

I confirmed that MA of AO-40 with WiSP3215 (GSC 2.03) was
approximately 9MA fast in 2002, although 126MA slow in 2000.
And, MA of AO-10 was approximately 19MA slow.

MA for the other satellite has the different error.
So, MA of WiSP3215 (GSC 2.03) seems to have many errors.

Now I think the orbit number of all the satellites increments at
perigee. However, NASA for Shuttle missions uses the ascending
node where increments the orbit number when the satellite crosses
the equator (going northward).
