4 - 8 LUNAR SURFACE NAVIGATION A. Test Objectives G-1 Determine the Location of the Landed LM from LM Data G-2 Determine the Location of the Landed LM from CSM Data G-3 Determine Capability of Locating the Landed LM in Real Time from LM/CSM/MSFN Data L-4 Panoramic Coverage of Distant Terrain Features M-2 Photograph Lunar Surface Post Touchdown/Pre EVA B. Test Requirements 1. Correlate lunar surface features surrounding the landing site with photomaps and mark the LM location. [G, L, M] 2. Photograph terrain features thru the LM window to correlate LM location. [G, M] 3. Obtain two sets of LM IMU alignments after landing [G] 4. Provide TV coverage of prominent terrain features. [G, L] 5. Track the landed LM from the CSM during two orbital passes. Mark on a landmark near the landed LM. [G] - (Only one pass is implemented.) 6. Track the CSM with LM RR during one pass. [G] - (Not Implemented.) 7. Obtain 70 MM photographs of the landed LM or its shadow and the surrounding lunar features. [G] 8. Assist MCCH in determining the landing LM location in real time. [G, L] C. Procedures/Checklist 1. Photographic and Television Operations Plan. 2. LM AOH, „PGNCS Lunar Surface Align Program (P57)“. 3. LM AOH, „Lunar Surface Navigation Program (P22)“ 4.
