12 Jan 1961 Jahr - First meeting

Beschreibung:

The Group for Guidance and Control drew up a list of suggestions for research and development programs:
• An "absolute emergency" navigation system in which the crew would use only a Land camera and a slide rule
• The possible applications of the equipment and test programs to be used on Surveyor
• The question whether Apollo lunar landing trajectories should be based on minimum fuel expenditure-if so, doubts were raised that the current STG concept would accomplish this goal
• The question whether radio ranging could be used to reduce the accuracy requirements for celestial observations and whether such a composite system would
fall within the limits set by the Apollo guidelines
• The effects of lunar impact on the return spacecraft navigation equipment
• Studies of hardware drift-error in the guidance and navigation systems and components
• A study of the effect of rotating machinery aboard the spacecraft on attitude alignment and control requirements
• Problems of planet tracking when the planetary disk was only partially illuminated
• A study of the transient effects of guidance updating by external information
• One adequate guidance and control concept to be mechanized and errors analyzed and evaluated
• The effects of artificial g configurations on observation and guidance.
• The development of a ground display mission progress evaluation for an entire mission
• An abort guidance sequence including an abort decision computer and pilot display
• An earth orbit evaluation of the position computer input in a highly eccentric orbit ( 500- to 1000-mile perigee, 60,000-mile apogee).
