[Show abstract][Hide abstract] ABSTRACT: This paper provides a status of the RADARSAT-2 system and operations performance, describes significant changes implemented over the last year, and also provides further detail of some of the data and value-added product delivery achievements demonstrating the utility of the RADARSAT2 system. The status of the spacecraft and ground segment is reviewed along with related performance metrics and recent history. Status of the system operations functional areas – Operations Management and Mission System Engineering, Order Handling and Mission Planning, Spacecraft Operations, and Data Handling is summarized. The MDA GSI RADAR Production team had a record production year in 2010, which included preparation of an Antarctica mosaic as well as products to service several large area DEM projects. The performance results are summarized. A number of system upgrade and improvement initiatives have been underway during the routine phase of the mission. Several of these have now been completed. The paper provides further information on the details of these enhancements and their implementation. Outline planning for further system and operations enhancements are summarized.
[Show abstract][Hide abstract] ABSTRACT: This paper provides a status report for RADARSAT-2 system operations and performance now that two years of Routine Phase operations have been completed. Experience from the second year of operations is reviewed. System status, performance, and trends are described along with performance and achievements of the RADARSAT-2 operations functional groups. Normal operations now includes increased attention to orbital collision risk avoidance, and the RADARSAT-2 risk mitigation experience is summarized. In addition to meeting and maintaining specified performance requirements for the Routine Phase, the operations team has implemented a number of improvements to both the system and operations to provide enhanced performance. These include reduced tasking latency, enhanced beam modes, and further improved image quality. The improvements are described as part of the evolution of the mission capabilities along with some further planned enhancements.
[Show abstract][Hide abstract] ABSTRACT: Following launch on SOYUZ in December, 2007, the RADARSAT-2 Satellite went through intensive Launch and Early Orbit Phase (LEOP) appendage deployment and attitude configuration activities. The first SAR data, including a remarkable Quad Pole image of Greenland, was acquired on-board on Day 4 of the mission as part of an extensive system commissioning campaign. The initial period of system operations saw introduction of a new high resolution imaging mode, demonstration of rapid tasking capabilities, successful operation through the first annual eclipse season, implementation of a new regulatory framework for control of user access to imagery, and continuous system improvement through tuning and enhancement of performance and to improve operations robustness. This paper provides a summary of the achievements and status of system operations and performance. Comparisons with pre-launch expectations, specifications, and plans are made to draw lessons from the flight experience. Plans for sustaining and enhancing system operations performance are outlined.
