Special purpose point- to-point circuits are provided to the joint tactical user over existing UHF satellite facilities. These include both the AFSATCOM network and the FLTSATCOM network. However, it shouid be noted that norma] access for joint exercises contingencies is through the AFSATCOM wideband channels supported by UHF transponders. These ; transponders are located on rhe FLTSATCOM satellites, Satetif{te Date Syatems (SDS) satellites, and Lincoln Experimental Satellites 8 and 9 (LES 8 and 9). Since these satellites are also shared by many users, a contro] mechanism has been established for accessing and using these facilities. Procedures to be followed for gaining access to these networks are outlined in a document entitled: “AFSATCOM Communications Control and Operational Concepts (C)," (Reference A-13). Communications channels supported by thessa links to either AUTOVON, AUTODIN, or AUTOSEVOCOM facilities can be ; extended at selected UHF terminal locations as discussed in Reference A-13. Factors that must be considered by the joint planner are discussed below. 3-5.2.1. UHF Satellite Access Request. Figure 3-2 depicts the message format used te request access to the UHF satellite network. Primary Control] Centers (PCCs) for this network are listed in Table 3-1. Unless otherwise directed, users west of the Mississippi River should send request messages to 33 ISG MARCH AFB CA//DODB/, and users east of the Mississippi shculd send requests to DET 2 2045CG BRANDYWINE MD//DOND//. Information copies should be sent to SISD OFFUTT AFB NE//YKO/YKOP//. Characteristics of the AN/WSC-3 used as a UHF ground terminal in this net. are discussed in Volume IV, Chapter 17. System performance factors that gust be considered are discussed below. 3°5.2.2. UHF Satellite System Parformance Parameters. The AN/MSC-71 UHF satellite terminals are upgraded terminals that will allow operation in either the narrowband (5 kHz) or wideband (25 kHz) channels. The AN/URC-101 UHF terminal operates in the 25 kHz mode and is compatible with the AN/MSC-71 (or AN/WSC+3) in the wideband mode of operation. Details which wust be considered in UHF satellite system engineering sre discussed in Volume IV, Chapter 16.
