TRACKING AND DATA ACQUISITION

The ground support network for GT-4 will be the Gemini Manned Space Flight Network (MSFN) illustrated in Figure 22 and tabulated in Table V. There will be, however, some minor modifications to the MSFN for the GT-4 mission. These changes for the GT-4 flight are primarily in locating the range tracking ships in positions most advantageous for the orbits to be flown.

* Remote Site Data Process (RSDP)

The ground network support facilities include the MCC-Houston, Cape Kennedy (CNV), Air Force Eastern Test Range (AFETR) downrange stations, the MSFN, and Goddard Space Flight Center (GSFC). Real time tracking and the acquisition of data for post flight evaluation will be provided by optical and photographic systems, MISTRAM, GE Mod III radar, C-band radar, and the Impact Predictor (IP) 7094. The network as listed in Table V will monitor spacecraft and launch vehicle PCM telemetry. The flight controller-manned stations, as shown in Table V will display selected spacecraft data for real-time evaluation and transmit these data to the MCC via teletype. The MCC will use both the Digital Command System (DCS) for transmitting commands. All the remote sites that are flight controller-manned, except for GYM, will have the DCS command capability. Tone commands for use by the Range Safety Officer will be used for manual fuel cutoff (MFCO), auxiliary second stage cutoff (ASCO), and Destruct.
