ground command of the spacecraft, instrumentation systems data transmission, and postlanding and recovery data transmission. The sole links between the ground and the Gemini spacecraft are provided by these systems. The ATDA communications system(antennas, beacons, telemetry transmitters, rendezvous radar, and digital command system) allows radar tracking of the vehicle from both the ground and the Gemini spacecraft. Ground station and Gcrnini spacecraft commands to the ATDA also are accomplished through these systems.

Shore stations for USNS Rose Knot and USKS Coastal Sentry Ship support will be based upon the mission-designated ship positions -25-
and predicated HF radio propagation conditions. NETWORK RESPONSIBILITY Manned Spacecraft Center (MSC), The MSC has the overall management responsibility of the Gcmini program. The direction and mission control of the Network immediately preceding and during a mission simulation or an actual mission is responsibility of the MSC. Goddard Space Fliqht Center. The NASA Office of Tracking and Data Acquisition has centralized the responsibility for the planning, implementation, and technical operations of manned space flight tracking and data acquisition at the Goddard Space Flight Center. Technical operation is defined as the operation, maintenance, modification, and augmentation of tracking and data acquisition facilities to function as an instrumentation network in response to mission requirements. About 370 persons directly support the network at Goddard; contractor personnel bring the total network level to some 1500. Department of Supply, Australia. The Department of Supply, Commonwealth of Australia, is responsible for the maintenance and operation of the NASA station at Carnarvon, Australia. Contractual arrangements and agreements define this cooperative effort . -26-
