US Navy's Space and Naval Warfare Systems Command (SPAWAR)

Terminal Control Software (TCS)

FORTRAN to C++

History: Navy Multi-band Terminal (NMT) is a SATCOM terminal, which expands available bandwidth and provides support for ForceNet, the Navy's approach to network-centric operations. NMT provides an integrated communications capability that supports Extremely High Frequency/AEHF Low Data Rate (LDR)/Medium Data Rate (MDR)/Extended Data Rate (XDR), Super High Frequency band, military Ka band, and Global Broadcast Service (GBS) receive-only communications. Raytheon was defining a modernized NMT hardware and software architecture to support communications above two gigahertz and provide other functions as part of defining an architectural standard for future Navy satellite communications (SATCOM) based on the Software Communications Architecture (SCA).

Challenge: The existing Low Data Rate/Medium Data Rate Terminal Control System (TCS) of NMT, written in FORTRAN, was a high-quality, one-of-a-kind, mission critical, information system for which no viable commercial off the shelf (COTS) alternative was available. TCS required modernization into platform independent C++ to support the Space and Naval Warfare Systems Command (SPAWAR) NMT architecture and software requirements. To provide SPAWAR with the best modernization approach, Raytheon selected TSRI to transform the existing TCS FORTRAN code into C++ and to re-factor the C++ toward the desired target architecture. TSRI's fixed-price "integrator ready" deliverable was selected by Raytheon for its low technical risk, shortened schedule, and low cost. Raytheon awarded TSRI a sole source contract as the sole provider capable of 100% automated assessment, transformation and re-factoring of TCS while meeting the stringent SPAWAR quality standards.

Results: Using TSRI multi-language JANUS™ technology, TSRI transformed TCS into C++ and delivered a modern error free system compatible with the Wind River Tornado development environment and a Tornado modified GCC based compiler. Raytheon subsequently carried out an error-free installation of the modernized TCS system, embedded it into the target NMT test bed, and carried out system tests. Following successful system testing, TSRI carried out a fully automated re-factoring of TCS using JANUS™ and redelivered the re-factored TCS system to Raytheon. The re-factored version of TCS operated flawlessly and completed testing without requiring further assistance by TSRI. In October 2003 the SPAWAR awarded Raytheon a $23.3 million addition to NMT that included integration of TCS into NMT.
