Problems with antennas for the Apollo spacecraft
Ralph S. Sawyer, Chief of the Instrumentation and Electronic Systems Division, advised ASPO Manager Shea of current problems with antennas for the Apollo spacecraft:
- CSM high gain antenna
- the infrared (IR) earth tracker originally proposed would not satisfy mission requirements.
On September 23, Sawyer reported, North American had ordered Dalmo-Victor to halt development of IR systems and to proceed with work on an RE tracker.
CSM S-band omnidirectional antennas
release of specifications was delaying subcontract award. North American might be unable to meet delivery for CSMs 017 and 020.
North American's in-house development program
because of a lack of qualified personnel in California, North American proposed to develop VHF scimitar, S-band flush mounted, and C-band antennas at its Columbus, Ohio, facility.
LEM S-band high-gain antenna
Dalmo-Victor predicted that preproduction models would weigh 11 kg (25.33 lbs), 3 kg (6.83 lbs) more than the specification weight. Grumman already had ordered Dalmo-Victor to study ways of lightening the antenna.
