| | Enhanced Position Location Reporting System (EPLRS) |
| | Primary Purpose | The Enhanced Position Location Reporting System |
| | (EPLRS) provides Marine Forces with a critical |
| | command and control tactical data distribution |
| | network. EPLRS links the dynamic Marine |
| | Air-Ground Task Force (MAGTF) Command, Control, |
| | Communications, Computers, and Intelligence (C4I) |
| | tactical data system architecture with a robust, |
| | user-transparent, automatic relaying, and |
| | automatic rerouting communications network. The |
| | EPLRS is a digital transmission system that |
| | provides the digital RF backbone necessary for |
| | the movement of information between MAGTF C4I |
| | Tactical Data Systems (TDS), such as the Tactical |
| | Data Network (TDN), Intelligence Analysis System |
| | (IAS), Tactical Combat Operations (TCO) system, |
| | Advanced Field Artillery Tactical Data System |
| | (AFATDS), and Data Automated Communications |
| | Terminal (DACT). The end product is |
| | communications connectivity to support a |
| | flexible, seamless, and integrated MAGTF C4I |
| | tactical data architecture below the regimental |
| | level. EPLRS will be the primary entry node for |
| | sensor collected information from forward |
| | deployed units for digital transmission to higher |
| | headquarters. |
| | Sub-Functions | Provides situational awareness as backup to GPS. |
| | Equipment Requirements | AN/VSQ-2C(V)2, EPLRS Radio Set AN/TSQ-158(V)4, |
| | Downsized Enhanced Net Control Station |
| | (NCS-E(D)). |
| | Connectivity Requirements | Network of EPLRS RS controlled by the Network |
| | Control Station. End User Data Terminals will |
| | connect to the EPLRS RS via standard Ethernet or |
| | X.25 protocols. |
| | Crypto Requirements | EPLRS RS: embedded KGV-13. |
| | NCS: KOK-13A. |
| | Normal Locations | The EPLRS RS will be fielded to infantry, |
| | artillery, Light Armored Vehicle (LAV), tank, |
| | AAV, and mobile command units. The NCS will be |
| | fielded to Division Communication Companies. |
| | Information Managed | Primarily any digital data or information passed |
| | via TCP/IP protocol and relative location of |
| | friendly units, waypoints and pre-designated |
| | items. |
| | Products Created | EPLRS provides data distribution vertically and |
| | horizontally between various tactical data |
| | systems. EPLRS inherent capabilities will also |
| | provide position location identification and |
| | navigation services to users. EPLRS position |
| | location reports are provided to automated |
| | systems in Command and Control (C2) centers for |
| | maintaining near real-time situational awareness |
| | displays. EPLRS primary purpose will be that of |
| | the digital RF backbone necessary for the |
| | interconnectivity of MAGTF C4I TDN. |
| | Lead Service/Contractor | USA/Raytheon. |
| Current Fielding Status | Full fielding was begun in FY00 at I MEF. |
| Initial Operating Capability (IOC) was achieved |
| in July 2000 with the initial fielding of I MEF. |
| Initial Fielding of II MEF was completed in |
| December 2000. Full fielding to III MEF will |
| commence in March 2001. Upon completion of III |
| MEF fielding, I MEF and II MEF will receive their |
| complete fielding. MARFORRES fielding will |
| commence during FY02. Final Operational |
| Capability (FOC) is anticipated during FY03 when |
| fielding will be complete. The PLRS system is |
| being phased out of the Marine Corps inventory as |
| EPLRS is fielded. |
| Known Problems | Fielding timeline is dictated by production rate |
| of EPLRS radios. |
| DIICOE Compliance Rating | Not rated. |
