  • Central Station power and thermal balance 
    Douthat, D. Z. (Bendix Systems Division, 1966)
    This memorandum defines the manner in which central station heaters, power dumps and experiment standby are to be arranged. The five switched central station heaters are replaced by two switched power dumps.
  • Development of a power dissipation model for the Power Conditioning Unit (PCU) 
    Wilburn, Frank E.; Wilson, H. W.; Wilson, H. W. (Bendix Aerospace Systems Division, 1968)
    This memorandum summarizes the effort to develop a mathematical model of the power dissipation within the PCU and to adapt that model to assist in the central station power/thermal analytical studies that have been required ...
  • Impact of open lines in experiment cables 
    Wilson, H. W. (Bendix Aerospace Systems Division, 1969)
    The purpose of this EATM is to answer the questions raised at the PSEP CDR regarding cutting the unused experiment cables. It is shown that there will be no impact on system performance as a result of cutting/these unused cables.
  • Power profiles 
    Wilson, H. W. (Bendix Systems Division, 1966)
    This document illustrates the detailed variations in the operational load of the subsystems of ALSEP. This information has been generated in response to Action Item B5-0712-20B which resulted from System PDR Change No 13-12.
  • PSEP command list 
    Wilson, H. W. (Bendix Aerospace Systems Division, 1969)
    This memorandum presents the current inventory of commands applicable to the Passive Seismic Experiment Package. This revision reflects changes in the initial functional mode of the equipment as it is delivered to the lunar ...
  • PSEP power requirements 
    Wilson, H. W. (Bendix Aerospace Systems Division, 1969)
    This memorandum provides data on the "normal" operating power requirements of PSEP as well as indicating the variations from this "normal" power demand caused by, commanded mode changes, thermal support power demands and ...
  • Recommended operations plan for Passive Seismic Experiment Package 
    Wilson, H. W. (Bendix Aerospace Systems Division, 1969)
    This memorandum provides revised planning information on the special activities necessary to prepare PSEP for flight, to initiate lunar operation and to establish the proper conditions for lunar night survival and subsequent ...
  • Solar interference with lunar communications (1968-1973) 
    Vredeveld, H.; Wilson, H. W. (Bendix Systems Division, 1965)
    Preliminary calculations are made to determine the effect of solar radio interference on reception from lunar-based transmitters. The magnitude of the noise received from the sun is calculated. Based on an assumed antenna ...
  • The effect of changes in reserve power on Central Station thermal control 
    Wilson, H. W. (Bendix Aerospace Systems Division, 1967)
    Presents a discussion of the interdependence of ALSEP system electrical operation and the thermal balance of the electronics bay in the central station. The sensitivity of variations in electrical dissipation in the central ...
