OVERVIEW The Harris Rugged, Deployable SATCOM (RDSAT) Terminal provides a technically superior multi-band satellite communications solution to meet demanding mission environments encountered throughout the world. High-performance baseband and RF components are seamlessly integrated into weather-resistant, ruggedized transit cases to provide the SATCOM operator with a lightweight, highly transportable terminal that is inherently expandable. RDSAT provides a tri-band capable terminal that operates in C-band, X-band, and Ku-band, and is upgradeable to Ka-band. A 2.5-meter transportable antenna and pedestal are combined with VME-based transit cases to provide a single-Spoke capability. The RDSAT Terminal is easily upgradeable to a four-downlink Hub by the simple addition of VME cards to the existing transit cases. The RDSAT Terminal system architecture is designed to support full-duplex Ka-band operations and expansion to operate as a six-downlink Hub terminal. In addition to the 2.5-meter antenna, the RDSAT Terminal is capable of controlling and operating four DOD legacy antennas: the AS-4429/TSC (LHGXA), AS-3036 (GMF 8 ft), AS-3199 (LT) and OE-361 (QRSA). SYSTEM DESCRIPTION The RDSAT Terminal is comprised of two major assemblies: the 2.5-meter antenna and the two transit cases.The 2.5-meter antenna incorporates a very rugged, tubular-aluminum pedestal coupled with a high-efficiency reflector and feed design to provide superb performance throughout the C-, X-, Ku- and Ka-bands. The interchangeable antenna panels and feeds ensure that rapid deployment and band change timelines are met. The two transit cases provide a very robust, environmentally sealed enclosure for the flexible, modular, scalable suite of SATCOM electronics. The transit cases are designed to operate in the open environment and are impervious to dust, salt fog and rain. Through the use of separate block and fine-tune converters, 250 feet of separation is possible between the antenna transit case and the baseband electronics transit case. Additionally, the use of VME chassis and modules provides an easily maintainable, highly reliable system. DSCS AND INTELSAT CERTIFIED The RDSAT Terminal utilizes an existing DSCS- and INTELSAT-certified design. The 2.5-meter antenna, Low Noise Amplifiers (LNAs), High Power Amplifiers (HPAs) and RF chain have been successfully tested to meet both DISA and INTELSAT certification requirements. DSCS Certification is being completed, and INTELSAT Type Approval has been received for C-band (Gx) and Ku-band (E1).CONTROL, MONITORING AND ALARM The RDSAT Terminal utilizes Harris. field-tested, proven CMA user interface to provide exceptional control and monitoring of terminal performance. The CMA server allows the remote control of the terminal up to 1,000 ft.SYSTEM CUSTOMIZATION The RDSAT Terminal is inherently customizable and upgradeable to meet user requirements.
