This research applied an intelligent controller for mobile satellite antenna tracking system design. The intelligent controller is with both the traditional PI and the fuzzy control methods. The antenna tracking and the stabilization loops were designed firstly according to the bandwidth and phase margin requirements. However, the performance would be degraded if the tacking loop gain is reduce...

This paper presents a project given to the students of a real-time system course. The project consists of developing a software for tracking in real-time non geostationary satellites. Students have to analyze , design, program, and test their solution. The project is not solely a simulation. There is a satellite tracking lab where students can really experiment and validate their solution. This...

BACKGROUND To evaluate pancreatic tumor motion and its dynamics during respiration. METHODS AND MATERIALS This retrospective study includes 20 patients with unresectable pancreatic cancer who were treated with stereotactic ablative radiotherapy. An online respiratory tumor tracking system was used. Periodical maximum and minimum tumor positions with respiration in superior-inferior (SI), late...

IEEE Network • September/October 1998 he global information infrastructure (GII) of the United States has included satellite asynchronous transfer mode (SATM) as part of the communications infrastructure to support global mobile communications, information transport and access. The Telecommunications Industry Association (TIA) has recently formed an SATM group to study the various technical iss...

Robotic service vehicles are presently seen as a viable means for performing satellite maintenance and ESA (European Space Agency) is presently investigating the possible characteristics and potential of a Geostationary Service Vehicle (GSV). A stereovision tracking system should be included in this GSV to help the operator track and capture the target satellite. This paper deals with a system,...
