The discussions therefore reflect the presence of a typical medium-sized com­ puter for the OCC and a typical large-sized computer for the NDPF. Al­ though all the functions to be performed in every case remain unaltered, the final ADPE selection of an IBM 360/85 and 44 configured as described in Final Report Volume 14, Section 5, and Proposal Part II, Volume 19, Section 2. 5, does result in certain differences in implementation. For example, it is stated that the OCC computer accepts PCM telemetry and writes a machine readable tape which is then used by the NDPF computer for the preparation of the master digital tape and extraction of attitude and annotation data. The processing functions in handling PCM telemetry are unchanged but the selected ADPE complex eliminates the need for the inter ­ mediate tape handling (OCC to NDPF) by utilizing high speed disc storage accessible by both computers. Similar differences appear between the ADPE assumptions under­ lying the discussions and the actual ADPE design finally selected. In no case is there a reduction in capability and in many cases performance im­ provement is attained. iii PRECEDING PAGE BLANKfNOT FILMED.

OPERATIONS CONCEPTS This volume describes the TRW design of the ground data handling system (GDHS). As an expository document little attempt is made in this book to present those design analyses and tradeoff studies which were a necessary concommitant to the synthesis of the system. Such background studies appear in other portions of this final report, particularly in Volumes 2, 15, 16, and 17. Consequently, in the following pages, the reader is given an unencumbered view of the GDHS configuration. Appropriate cross-references are provided to other report volumes wherein the rationale for certain design decisions may be found. The GDHS top level specification is included in Volume 2 of this report. Subsystem specifications for the GDHS personnel subsystem, the OCC, and the NDPF are included as an appendix to this volume. Detailed equipment and software specifications (software Milestone B) constitute Volumes Z0 and Zi of the proposal, Part II. i. i OVERALL PHILOSOPHY The elements and functions of the GDHS are shown graphically in Figure 1-1 and are described in detail in Sections 2 through 6 of this volume. The key to GDHS operations is on-line interactive support by separate but compatible computers in the operations control center (OCC) and the NASA data processing facility (NDPF). A unified display system augments the heuristic and judgmental efficiency of the human operators by providing the necessary man-machine interface with the highly efficient digital processors. Allocation of functions to hardware, computer software, or human operations has been based upon detailed studies of operations and functional requirements, and description of which may be found in Volume 15. The computer-based system is organized such that vital activities may continue manually during those periods of time that the automatic data processing equipment (ADPE) may be out of service. Furthermore, the tasks carried out by the OCC computer can be assumed by the NDPF computer, thereby providing complete machine backup for the OCC. i Certain activities are implicit to the relative objectives of the OCC and the NDPF as defined by the governing NASA specification S-20i-P-3.
