DSCS
IPBC Study
| Question | Answer |
|---|---|
| DSCS | Defense Satellite Communication System |
| DSCS Communication Payload Ownership | Army |
| SHF | 3GHz-30GHz |
| SHF Adv | HDR. Joint Interoperability |
| SHF DIS | DSCS overcrowded, CBSP expensive |
| WSC 6 | DSCS |
| WSC 8 | CBSP |
| DSCS provides... | IP Services, NIPR/SIPR, JDISS, GCCS, POTS, VTC, JWICS |
| HDR | > 1.544 Mbps |
| GBS provides | UAV video, training videos, ATO, MDU, Imagery, JSIPS-N, METOC |
| DSCS purpose | to satisfy GCCS requirements and provide vital Command, Control, and Communications service to U.S. forces throughout the world. Primary operational objective is to provide high-quality communications to validated users. |
| VTC requirements | Minimum: 128Kbps (64 voice, 64 video) 256K, 384K better |
| DSCS constellation | 5 satellite constellation with 5 residual satellites. Anti-jam, nuclear hardened. Six independent channels on each satellite. |
| DSCS advantages | global coverage with 5 reserve satellites, interoperable with other agencies, minimal atmospheric interference, up to 7Mbps footprint, |
| DSCS disadvantages | insufficient allocation to meet Navy needs, Navy does not control space segment, |
| Largest user of DSCS | provided for the Intelligence community for the dissimenation of imagery and other INTEL products |
| SLEP | Service Life Enhancement Program. Initiative to enhance the tactical appliction of DSCS to disadvantaged users. |
| SLEP enhancements | 200% increase in throughput capacity, greater flexibility/coverage, more efficient satellite, improved anti-jamming |
| WGS | Wideband Gapfiller system. DoD owned, high capacity, military satellites. 1.2 Gbps to 3.6 Gbps. |
| WSC 6(v)5 | Command ships, CVN, LHA, LHD, LPD-17. Two channels (two rf carriers). Allows for connectivity to shore and deployed units. |
| WSC 6(v)7 | TLAM/Aegis Cruisers, LPD, LSD. Single carrier. Can only execute at a STEP site |
| WSC 6(v)9 | DDG. Dual military carrier, single commercial carrier. |
| SHF Multiplexer | Timeplex Link/2+. Full or Half Duplex. 12 trunks at 4.8 kbps. |
| DSCS STEP Sites | Wahiawa, Hawaii; FT Buckner, Northwest, Lago Di Patria, Landstuhl, Germany; Bahrain |
| Overall management of DISN | DISA |
| Overall responsible for DSCS control | DSCS Operational Control Systems (DOCS). Internal to DISA. |
| DOCS is comprised of... | DISA Operations Center, two Regional Network Operations and Security Centers (RNOSC) and Five DSCS Operations Centers (DSCSOC) |
| Five DSCS Operations Centers | Ft. Buckner, Ft. Meade, Ft. Detrick, Camp Roberts, and Landstuhl |
| USSTRATCOM | system operations manager for the DTD management of MILSATCOM, conduct SATCOM space ops |
| DSCS platform control | Airforce |
| DSCS Network Manager | controls management of DSCS assets, assign access and allocate bandwidth |
| Global/Regional Network Operations and Security Centers | provide comm service to users, focal point for restoration efforts, provides comm planning and direction |
| GSSC | Global SATCOM Support Centers. global operations forcus for constellation management, centralized management for global SATCOM requirements |
| RSSC | Regional SATCOM Support Centers. Full spectrum SATCOM support, resource management, plan SATCOM network/payload reconfigurations, review and respond to SAR?GAR, allocate resources, allocate SAAs (satellite access authorizations) |
| DSCSOC | manage/control assigned satellite comm payload/networks. control satellite user access. execute satellite configuration changes. |
| DSCSOC locations | Ft. Buckner, Ft Meade, Landstuhl, Camp Roberts, Ft. Detrick |
| STEP | Standardized Tactical Entry Point. |
| STEP Purpose | provide JTFCOM with direct access to DISN. enable interoperability between joint forces, support access to two DSCS satellites, provide access to naval shore C4I services through the ADMS, access to JDVM services |
| ADMS | Automate Digital Multiplexing System. Provide access to naval shore C4I services. AKA N-STEP. |
| JDVM Services | JDVM-Joint Voice and Data Networks. Include DSN (Defense Switched Network), DRSN (Defense Red Switch Network), NIPRnet, SIPRnet, JWICS, VTC |
| DoD Teleport | STEP Follow on. controls variety of comm interfaces between DISN terrestrial and tactical SATCOM assets. |
| Teleport Sites | |
| Satellite Access Request | SAR- must be submitted any time user requesting access to DSCS/Navy C4I services ashore. Must be submitted 14 days prior to use. |
| GAR | Gateway Access Request. submitted when access to STEP pre-positioned JVDN services is required. Must be submitted 21 days prior to use. |
