Abstract

12 The majority of recently installed remote-sensing groundstations use computer-based data recorders (sometimes referred to as direct ingest or direct capture systems) rather than the high-density tape-recorders used in earlier systems. Direct ingest systems offer significant advantages over high-density recorders, including improved performance, lower initial and operating costs, better reliability and easier system automation. This paper describes a direct ingest system designed for use in new systems or in upgrades to existing systems. It is being used in several recently commissioned groundstations. The design accommodates applications ranging from a simple manually controlled data recorder to a fully automated data acquisition, quality-analysis, archiving and retrieval system. The only specialized hardware is a serial data I/O card that can transfer data at rates exceeding 400 Mb/s. All other functions, including real-time format synchronization and image generation, are carried out in software. The design is open, modular and flexible. The main components may be used separately or as part of a complete system. Satellites currently supported include ERS, KOMPSAT, Landsat-7, Radarsat and SPOT. End-users can easily customize the system to meet their own requirements and can integrate their own satellite-specific processing modules.
