- The AN/TSQ-158, Enhanced Position Location Reporting System (EPLRS) provides a computer controlled communications network which transmits digital information to support tactical operations on the battlefield. EPLRS provides two major functions; data distribution, and position location and reporting. Speed of service and throughput requirements for priority data users and reliable data communications are the prime data features. Computing and reporting position location, navigation aids, and friendly identification are the key battlefield visibility and synchronization features.
- EPLRS is a synchronous Time Division Multiple Access (TDMA) system that provides the basic tactical functions of identification, position location, and navigation information automatically to a centralized NCS. It reports this information to commanders and supported users with the EPLRS community upon request. it provides near real-time data communication support to weapon system sensors and other Battlefield Automated Systems (BASs).
