CHAPTER 1

SYSTEM DESCRIPTION

1.1 PURPOSE.

This manual is designed to provide operators of the Global Positioning System (GPS) Information Network (GIN) with the neces-sary information and procedural guidance required to update, maintain and transfer controlled files. This section provides general information, manual layout and GIN overview including GIN hardware and software (SW) identification.

1.2 SYSTEM NAME AND IDENTIFICATION.

This technical order is for the GINwhich is located at theMaster Control Station (MCS) and is operated and independently controlled by the 2d Space Operations Squadron (2 SOPS), Schriever Air Force Base (SAFB), CO. The backup GIN is located at the Alternate Master Control Station (AMCS), Vandenberg AFB (VAFB), CA, in Bldg 23229 of the Vandenberg Tracking Station.

1.3 SYSTEM DESCRIPTION.

The purpose of the GIN is to provide 2 SOPS with the Information Technology (IT) infrastructure and tools required to support implementation of effects based GPS operations, Constellation Management, and User Services activities. Within 2 SOPS, the GPS Operations Center (GPSOC) is the primary user of the GIN. The operational need for this support is established in the AFSPC Operating Concept for GPS, the Joint GPS Warfighter Concept of Operations (CONOPS), and the Trilateral GPS MOA between Joint Forces Component Command-Space, U.S. Coast Guard Navigation Center, and FAA National Operations Control Center. A backup GIN is co-located with the AMCS at Vandenberg, AFB. During normal operations, the backup GIN is in a powered-off state. During routine deployments or emergency operations, the backup GIN serves as the operational network of the GPSOC. An overview of the GIN is presented in Figure 1-1.

The GPS Information Service (GPSIS) is a suite of automated data collection, processing, and distribution software that resides on the GIN and the GPSOC’s Secret Internet Protocol Router Network (SIPRNet) web server. The GPSIS provides near real-time GPS performance and status data in a machine readable format and serves as the GPS Operational Control System’s (OCS) prototype net-centric interface for distribution of authoritative GPS data. Data is distributed to users via a one-way connection from the GIN to the GPSOC SIPRNet web server, where users may access and download the data files via File Transfer Protocol (FTP). A description of the GIN Data Flow is shown in Figure 1-2.

1-1

Figure 1-1. Overview of the GPS Information Network.

1.4 SYSTEM INTERFACES.

The GPSIS interface with the SIPRNet is via a SIPRNet web server that hosts the GPSOC classified website, and supports the transmission of near real-time performance and status data to registered users. The web server is isolated from the rest of the GIN by a router, a firewall and a SIPRNet terminal (See Figure 1-2).

1-2

Figure 1-2. GPS Information Network Data Flow.

1.5 ACCREDITATION BOUNDARY.

The GIN boundaries are established at the routers that support the MCS interface for input data, and the routers that support the GIN FTP interface with the SIPRNet terminals and web servers. The input routers are protected by an access control list that only allows data to come from specific Internet Protocol (IP) addresses on the MCS External Users Interface server. The Output routers are likewise tied to a SIPRNet IP address. Both sets of routers function as one way firewalls. Data cannot be retrieved from an input router, nor can it be sent into the GIN through an output router (See Figure 1-3).

1-3

Figure 1-3. GPS Information Network Boundaries.

1.6 MASTER CONTROL STATION-ALTERNATE MASTER CONTROL STATION DESCRIPTION.

The GIN has two one-way external interfaces. These interfaces are:

• The GPS Master Control Station (MCS) and Alternate Master Control Station (AMCS)

• A Secret Internet Protocol Router Network (SIPRNet) Web Server

The backup GIN located at VAFB is functionally set up in exactly the same manner as the primary GIN. Physically, it differs in the fact that it only contains one Database Server and one File Server. There is no Tape Drive used for system data backup. It has been determined by 2 SOPS that this is sufficient to achieve mission accomplishment.

1.6.1 Master Control Station. The MCS is the command and control center used by GPS operators in Module 11, Building 400, Schriever AFB, CO. MCS activities include:

a. L-band processing of tracking data, navigation data and limited Space Vehicle (SV) health data.

b. S-band processing of telemetry, commands and navigation uploads.

c. Controlling and monitoring OCS resources.

d. Providing and receiving GPS performance and operational data to and from other agencies.

The MCS includes numerous operator workstations. A typical workstation consists of monitors, a Sun computer, keyboard, 3-but-ton mouse, laser printer, and resident software. In addition to the workstation, a phone system provides the user with internal and external voice communications. Internal MCS communications between workstations, servers, and other components is primarily provided by a Dual-Homed Gigabyte Ethernet Local Area Network (LAN) backbone. A secondary Ethernet Hub provides local

1-4 connectivity between servers and single monitor workstations. The Automated Remote Tracking Station (ARTS) Versa Module Eu-robus/Eurocard provides external communications with the Air Force Satellite Control Network ARTS. A gateway provides external communications with Air Force Technical Applications Center office located in Module 15, SAFB Colorado. External communi-cations between the MCS and the Ground Antenna (GA)/Monitor Station (MS) are encrypted and decrypted by crypto units and transferred via 14 full duplex circuits.

The communications network is controlled by the Defense Information Systems Agency and is supported by various other means such as the fiber optics between Schriever and Peterson AFB, commercial communications companies, and Defense Satellite Com-munications System links to remote sites.

1.6.2 Alternate Master Control Station. The AMCS equipment is functionally identical to the operational equipment in the MCS. If the MCS becomes disabled, the AMCS provides for a redundant control center. The AMCS is located at Vandenberg AFB, CA.

1.6.3 Monitor Stations. Monitor Stations (MSs) for the OCS are operated under the control of the MCS. The primary MS function is to monitor navigation signal quality and collect navigational data received from all GPS satellites. The information is sent at regular intervals to the MCS for processing. This continuous feedback of information allows the SV’s navigational data to be accurately maintained. The MCS analyzes all forwarded MS signal quality measurements and collected data. There are a total of six MSs. They are located at Cape Canaveral Air Force Station (CCAFS), FL, Ascension Island (South Atlantic), Diego Garcia Island (Indian Ocean), Kwajalein Island (South Pacific), Oahu Island, HI, and SAFB, CO.

Additionally, there are 14 National Geospatial-Intelligence Agency (NGA) Monitor Stations located at various locations around the world, which are controlled by the NGA Network Control Center in St. Louis, MO. The MCS interfaces directly with NGA to help maintain the GPS navigation message quality. The inclusion of NGAMSs along with the GPS MSs provides 100% worldwide coverage of the GPS navigation signals, thereby providing an increased ability to access signal integrity.

1.6.4 Ground Antennas. The Ground Antennas (GAs) for the OCS have the necessary equipment, computer programs, and facilities to conduct a contact with a GPS SV. There are a total of four GAs. They are located at CCAFS, FL, Ascension Island, Diego Garcia Island, and Kwajalein Island. GA operations consist of the MCS using GAs to transmit SV commands and uploads and to receive SV telemetry.

1.7 GPS INFORMATION NETWORK DESCRIPTION.

1.7.1 GIN Equipment Rack (MCS: 3A69) (AMCS: 3A69).

1.7.1.1 Tape Drive (3A69A1). (MCS Only) The GIN System uses a tape drive for system data backup. Each network server has an independent drive for data backup operations. Each tape drive is Ultrium formatted and has a 100 Gigabyte (GB), uncompressed, capability in a single cartridge. The data backup from each server hard drive to the respective tape drive is accomplished using the rack-mounted keyboard/video/mouse (KVM) and monitor for that rack and Veritas software.

1.7.1.2 Servers (MCS: 3A69A3, 3A69A5, 3A69A7, 3A69A11, 3A69A13, 3A69A15, 3A69A17, 3A69A37, 3A69A39, 3A69A41) (AMCS: 3A69A27, 3A69A29, 3A69A31, 3A69A33, 3A69A35, 3A69A37). The MCS GIN Rack has 10 separate dedicated servers each providing different functions. The AMCS GIN rack has six dedicated servers each providing the same func-tions as the MCS GIN rack. They are described as follows:

• GWSRV1 (MCS: 3A69A3) (AMCS: 3A69A33) and GWSRV2 (MCS: 3A69A5) (AMCS: 3A69A31) - Serves as entry point of data from the MCS, and collects data through the course of a Kalman point (K-point) and when all data sets have been received, forwards information to database server.

• MISCSRV (MCS: 3A69A7) - Provides miscellaneous functions for the GIN and serves as host to the Footprints database.

Mostly used as a data storage device.

• DC1 (MCS: 3A69A11) (AMCS: 3A69A37) and DC2 (MCS: 3A69A13) (AMCS: 3A69A35) - Domain Controllers for the GPS network and provides Active Directory and Domain Name Services.

• CS1N1 (MCS: 3A69A15) and CS1N2 (MCS: 3A69A17) - Database and File Server cluster. Processes and stores MCS data and creates file types used to create analytical products.

• DBSRV1 (AMCS: 3A69A29) and FILESRV1 (AMCS: 3A69A27) - These two servers provide exactly the same database and file server cluster processing as the CS1N1 and CS1N2.

1-5

• GLEN-GPSOCX1-S (MCS: 3A69A37) and GLEN-GPSOCX2-S (MCS: 3A69A39) - SIPRNet computers used to transfer data between GIN and SIPRNet ftp site.

• GLEN-GPSOCW1-S (MCS: 3A69A41) - SIPRNet Website/FTP Server.

1.7.1.2.1 Database Server (MCS: 3A69A15) (AMCS: 3A69A29). The Database server provides the majority of data process-ing functions associated with incoming raw data as well as providing the GIN with its assured data storage and archival capability. It is responsible for providing all the processed data sets required to support GIN operations. Data is edited and audited to ensure it is correct and consistent with expectations. Audit functions include relative comparisons between measured and estimated User Range Errors (UREs), and state estimates generated by the MCS and the GPSOC. The Database server supports the GPSOC requirement for performance monitoring independent of the MCS Kalman filter by generating its own precise state estimates and predicts. It also conducts constellation integrity checks, to ensure performance standards are being met and anomalies are detected in the shortest possible time. Since data products are required in near real time, intermediate data sets are stored in memory for speed. All data sets are also provided to the Database server for storage and archival. The Database server also provides processing for non-real time functions, such as generation of running statistics for prediction input datasets. Short and long-term archival is supported through connected Redundant Array of Inexpensive Disks (RAID) arrays and redundant storage on two Internet Small Computer System Interface (iSCSI) Storage Area Network (SAN) components. The Database server also contains separate databases for reported anomalies and Requests for Information (RFI).

1.7.1.2.2 File Server (MCS: 3A69A17) (AMCS: 3A69A27). The File server is responsible for all processing required to build real time and post-processing input data reports. These reports are used for internal GPSOC performance and status processing, and are also posted on the SIPRNet web server to support user needs for GPSOC data. Datasets generated for posting to the SIPRNet are defined in the GPSOC Interface Description Document. The near real-time data sets produced by the File server will be posted to the SIPRNet web server to be accessible to users via FTP. The SIPRNet web server connects to the GPSIS core network via a dedicated router.

1.7.1.3 Rack-Mounted Keyboard/Video/Mouse (MCS: 3A69A21) (AMCS: 3A69A20). Each keyboard and display has direct or interconnectivity to each chassis within those racks. The keyboard/flat panel display stows away in a tray configuration when not in use. This unit has a keyboard-mounted trackball as a pointing device. This connects to all the components and gives control to each of them.

1.7.1.4 Storage Area Network System (MCS: 3A69A25, 3A69A29) (AMCS: 3A69A15). The SAN1 and SAN2 at MCS and SAN1 at AMCS Storage Systems provide 3 TB of storage each. Each uses a Fiber Channel-Arbitrated Loop as an interconnect interface to host servers and uses the iSCSI protocol. Short and long-term archival is supported through connected RAID arrays and redundant storage on two iSCSI Storage area network components.
