Apparently the TRW AGS people have done a good job of putting the new rendezvous radar navigation filter into that dinky computer. In fact, they now estimate a surplus of some 80 words.
One of our brilliant
young engineers here in MPAD – Ed Lineberry – has
developed a simple technique for computing the CDI and CDH rendezvous
maneuvers provided the CSM orbit is near circular as it should be on
the G mission (reference MPAD memo, 68-FM61-B18, dated October 15, 1968,
subject: Linearized solution for CSI and CDH for a multiple-half-orbital-
period transfer between maneuvers!). In fact, he expects that it could
be fit into the aforementioned 80 words. He and Milt Contella have already
discussed this with the TRW people who are looking it all over. If things
go well, he expects they will come to the Software Configuration Control
Board with the proposal to include it in some future AGS program and we
can decided at that time if that is the best way to use our little 80 word
I wrote this because that idiot Ed Lineberry is too darn modest to tell anybody and I thought you might find it interesting.
