SAN ANTONIO, Oct. 23 /PRNewswire-FirstCall/ -- GEOINT 2007, Booth 475 -- To receive, process and distribute high-resolution imagery obtained by Malaysia's Earth observation satellite, Astronautic Technology Sdn Bhd (ATSB) selected a wide range of high-performance compute and storage technology from SGI . The SGI-powered real-time data processing system was installed in July in preparation for the launch of the RazakSAT(TM) spacecraft. Currently, Malaysian agencies requiring satellite imagery rely upon image data and information provided by satellites manufactured and operated by foreign companies. Due to the orbit in which these satellites are located, the images provided are neither timely enough nor do they cater to Malaysia's specific uses and needs. Malaysia's own satellite is a highly specialized payload requiring high performance ground ingest and processing capabilities that will provide specific and timely data for its users in Malaysia as well as catering to the needs of other countries located on the equatorial belt.

The RazakSAT satellite will be operated through its ground station in Malaysia, consisting of a Mission Control Station (MCS) and Image Receiving and Processing Station (IRPS), where the SGI systems are housed. ATSB's engineers are operators at the MCS and will execute RazakSAT's mission plan, command generation and telemetry receiving, archiving and analysis. Using the SGI real-time image and data processing system, which includes an SGI(R) Altix(R) 350 server running Oracle(R) as the database for their image processing application, the IRPS will receive images for archive, post-processing and distribution.

"The power of SGI Altix global shared-memory architecture is ideal for the data processing needs of high-resolution Earth imagery satellite data," said Shamsulazwan Samsuddin, Spacecraft Engineer, Astronautic Technology. "By providing 64-bit processing power to model the sensors and re-sample all this data onto a geographic system, SGI technology optimizes our application performance and interactivity for image manipulation and delivers real-time visualization with large models and enormous data sets."

The SGI system receiving and processing satellite image data in real time was developed to provide not only highly accurate image products but also systematic and automatic operation. The system is designed for multi-satellite data handling capability. ATSB selected SGI in part because of SGI's history of powering and optimizing satellite ground stations and easily expandable architecture, which includes 2TB of SGI InfiniteStorage that can grow with image and data requirements.

The development of the RazakSAT satellite system is a collaborative program between ATSB and SaTReC Initiative Co. Ltd., Republic of Korea. SaTReC Initiative provides a whole spectrum of Earth observation satellite systems including spacecraft buses, Earth observation payloads, communications equipment and satellite image receiving and processing systems. The overall objectives of the collaboration is to demonstrate indigenous spacecraft design and manufacturing competence, to get involved in all aspects of high-resolution image observations and processing in a near equatorial LEO orbit (NeqO) for a number of applications in developing countries, and to develop technology for future missions.

SaTReC uses a variety of off-the-shelf software and writes many in-house proprietary codes where much of the high-end value-added work for ATSB is produced. All the codes are written in an open system platform, which makes the Linux(R) OS environment of the SGI Altix systems compatible with the requirements set by the company. Additionally, according to ATSB engineers, the SGI Altix system powered by Intel(R) Itanium(R) 2 processors has some of the best floating point performance relative to fixed-point performance of any general-purpose microprocessor for their floating-point based application.

"Astronautic Technology researched other vendors and determined SGI delivered the bandwidth, compute power, and real-time performance necessary to process large data sets from Malaysia's first Earth-observation satellite," said Nicholas K. C. Low, Country Sales Manager, Silicon Graphics Sdn. Bhd, SGI's operating subsidiary. "SGI systems for satellite image processing are the choice of many government operations and universities throughout the world for their performance, reliability and security."
