2139 AUTOMATIC DATA STORAGE AND READOUT SYSTEM, CS-11 -
The prototype modules are nearing completion. Design of system 2 5X1A9A
controls and computation of required battery capacity are two
principal areas in which much work remains to be done. Uncertainty
in these areas is due mainly to the unavailability of complete
information on the functional characteristics and power requirements
of the GFE equipment. Wiring diagrams of this GFE equipment have
been drawn and sent to the contractor to relieve this situation.
