FA/Technical Assistant for ApolloAPR 3 196767-FM1-28FM/Deputy Chief, Mission Planning & Analysis DivisionLM S-band antenna boresight change presents no LGC problem
This memo is in confirmation of our telephone conversation March 30, 1967 regarding LM S-band antenna acquisition. As you are aware, some months ago we reinstated to MIT the requirement for providing DSKY displays of point- ing angles compatible with the astronaut's S-band antenna controls to assist him in acquiring the MSFN while in lunar orbit. (Actually, the pointing angles are those which, if utilized, cause the antenna to be pointed toward the center of the earth).
During our chat, I gave you assurance that the contemplated change in the alignment of the S-band antenna boresight would not seriously perturb the formulation of this LGC processor. Subsequent checking has reaffirmed that, so I say to you – “have at it”.
