LANHAM, MD, May 4, 2007 - Satnews Daily - Integral Systems, Inc. (NASDAQ-ISYS), has successfully demonstrated the ability of its CCS-C (Command and Control System - Consolidated) satellite control system to support satellite operations using the TCP/IP (Transmission Control Protocol/Internet Protocol) SLE (Space Link Extension) protocol.
The SLE protocol is being considered as a future standard interface between the Air Force Space Command (AFSPC) Satellite Operations Centers (SOCs) and the AFSCN’s Remote Tracking Systems for satellite telemetry and commanding. This effort is funded by the CRSS (Civil Reserve Space Service) Initiative, via Universal Space Network as the prime contractor.
The demonstration was conducted using the Multi-Mission SOC (MMSOC) deployed at the Air Force 1st Space Test Squadron at Schriever Air Force Base and the Universal Space Network (USN) RGS (Remote Ground Station) in Alaska. The MMSOC uses the same software and hardware as the Integral Systems-designed and -delivered CCS-C system.
During the demonstration, live telemetry from a retired DSCS (Defense Satellite Communications System) satellite was received, processed and displayed by the MMSOC equipment. Both telemetry and command interfaces between the MMSOC strings and the USN RGS were established over the SLE interface. SGLS (Space-to-Ground Link System) and USB (Unified S-Band) commands were sent by the MMSOC, transmitted over the SLE interface, and then looped back at the RGS antenna. The commands were verified at the MMSOC with the returned echoes.
“This demonstration further proves the flexibility of the CCS-C design to support legacy, future, and emerging satellite system requirements,” stated Jeff Benesh, Integral Systems’ vice president of Western Operations. “Demonstrating USB commanding through USN’s commercial network using the new SLE protocol is exactly the kind of extensibility for which the Air Force was striving when they developed the standard satellite control system concept on which CCS-C is based.”
Integral Systems is a provider of satellite ground systems and has supported over 205 different satellite missions for communications, science, meteorological, and Earth resource applications. Integral Systems was one of the first companies to offer an integrated suite of COTS (Commercial Off-the-Shelf) software products for satellite command and control: the Epoch IPS (Integrated Product Suite) product line. swen002
