USN DEMONSTRATES TCP/IP SPACE LINK EXTENSION WITH SATELLITE.

Universal Space Network, Inc. (USN), a leading provider of space operations and ground control and communications services, along with subcontractor Integral Systems Incorporated (ISI), has announced the successful demonstration of the TCP/IP Space Link Extension (SLE) with a U.S. Air Force (USAF) satellite utilizing Space Ground Link Subsystem (SGLS) and Unified S-Band (USB) receiving channels.

SGLS is the current Department of Defense (DoD) and USAF telemetry, tracking and command standard, and USB will be the telemetry tracking channel employed on many of the next-generation USAF satellites.

The demonstration under a USN contract with the USAF Space and Missile Center (SMC) successfully verified the SLE's capabilities using the Command and Control System-Consolidated (CSC-C) ground system deployed at the Air Force Center for Research Support (CERES) Satellite Operations Center (SOC) and the USN Remote Ground Station (RGS) in Alaska. The SLE protocol used is expected to become the command and telemetry interface standard between the user's SOCs and the Air Force Satellite Control Network's Remote Tracking Systems.

During the demonstration, live telemetry from an orbiting USAF test and checkout satellite, DSCS 3 A1, was received, processed and displayed by CCS-C equipment. Both telemetry and command interfaces between the CERES CCS-C strings and the USN RGS in Alaska were established over the CCSDS SLE TCP/IP interface. SGLS commands -- sent by CCS-C, transmitted over SLE and up-linked at the RGS -- were verified at CERES with the returned echoes.

"This demonstration represents a significant step forward in the evolution of standard interfaces to meet future satellite requirements for the Air Force," stated Ken Riley, USN's vice president of Customer Development. "It proved that commercial ground stations, using industry standard interfaces, can provide telemetry, tracking and command support to USAF missions using both the commercial USB and DoD SGLS standards."
