2.5 White Sands Complex 2.5.1 Description The WSC is the main controlling facility for the TDRS. WSC contains all of the Automatic Data Processing Equipment (ADPE) necessary to control the configuration of the TDRS services that support SPTR data transfer. The WSC is capable of generating all command sequences needed to perform antenna pointing based on processed ephemeris data and to configure the TDRS payload to meet user support requirements. 2.5.2. White Sands Complex Responsibilities a. Operate and maintain the TDRSS in response to NASA service support requirements. b. Provide terrestrial communications and data transmission for the customer community c. Develop, coordinate, implement, and maintain standard/contingency/emergency procedures for overall telecommunications satellite system and facilities under its control. d. Monitor and control each TDRS. e. Coordinate and schedule all anticipated service outages. 2.5.3 Tracking and Data Relay Satellite a. TDRS Spare positioned at 49 degrees West longitude is capable of providing a telecommunication data relay interface for any authorized user spacecraft. TDRS Spare provides S-band and K-band service capabilities for the relay of data recorded at the South Pole TDRS Relay facilities. b. At present only K-band services and S-band Single Access services are provided; no Multiple Access (MA) is required. 2.5.4 SPTR Equipment Configuration/Data Flow 2.5.4.1 General Command data transmitted to the South Pole via WSC uses the TDRS-1 SSAF service. User data transmitted from the South Pole via TDRS-1 may use the SSAR service for straight throughput to the user destination or use the KSAR service for store/forward at the WSC 2 GigaByte hard drive file server. All data transfer is automatic. The WSC file server processing recreates the science data files from the serial packetized data and places them in a file directory that replicates the file directory in the file server at the South Pole. NOTE The NCC and the WSC is not involved in the SPTR file transfer process or the management of the file server file directories. a2302s2 2-4 532-OIP-NCC/SPTR
2.5.4.2 User Forward Data User IP traffic data arrives at WSC via the NASA Science Internet (NSI) where the data in NRZ- L format is forwarded to the router and then the TDRSS Data Interface (TDI). At the TDI, the data is routed to a scrambler, a differential encoder for conversion to NRZ-M data, and then sent to a convolutional encoder. From the TDI the data is forwarded to the Low Rate Data Switch (LRDS) where it is then transmitted as S-band data through TDRS-F1 to the Elevated Dorm Facility (EDF) at the South Pole. 2.5.4.3 Return Data a. User data from the South Pole arriving at WSC is forwarded to the LRDS. Data arriving via the S-band service is routed to the TDI where the data is descrambled. From the TDI the data is forwarded to the router and sent to the requested destination via the NSI. b. User data arriving at WSC via the TDRS K-band service is forwarded to the LRDS and then to the White Sands File Server (WSFS) where the replication of the South pole user data files occur and then stored until retrieval. The data is retrieved by the South Pole user via FTP. Upon transmission, data is forwarded from the server to the router where it is then transmitted via the Interfacility Link (IFL) to the STGT router and then via the NSI to the user. Retrieval can be done 24 hours a day. 2.5.5 Staffing NOTE Currently, arriving K-band SPTR data is transmitted to the WSGT. In the future user data will be able to go to either STGT or WSGT. a. NASA Station Director (STADIR)/Assistant STADIR). The STADIR evaluates the site performance and acts as the Site Security Officer for the complex. The STADIR has the approval authority to implement procedures to respond to emergency conditions at the complex. The STADIR represents NASA in all official matters and directs the contractor in the overall maintenance and operations. The Assistant STADIR performs the STADIR’s functions during the STADIR’s absence or as directed by the STDIR. b. Site Manager (SM). The SM is the senior contractor representative for the complex. The SM provides the personnel to perform site management including management of ongoing day-to-day operations of the sire, security administration, Quality Assurance (QA) and Configuration Management (CM). The SM represents the STADIR and the Assistant STADIR in their absence. c. Operations Supervisor (OS). The OS is responsible for the overall operations support during the shift. The OS interfaces with all external entities as required to manage onshift operations and resources. The OS reviews/approves schedule modifications to the Integrated Schedule and reviews/approves Discrepancy Reports (DR) before distribution. The OS performs all administrative duties for the shift. The OS initiates technical investigations and coordinates changes/additions to operations procedures. a2302s2 2-5 532-OIP-NCC/SPTR
