Descripción
This paper analyzes a digital interface and bus system modeling and optimization of the SEOSAR/PAZ Earth Observation satellite. The important part of the satellite is an X?band Synthetic Aperture Radar instrument that integrates 384 Transmit/Receive Modules located in 12 antenna panels 7.5 m away from the central processor and controlled by a synchronous 10 Mbps bidirectional serial protocol. This type of mid?range point?to?multipoint transmission is affected by bit errors due to crosstalk, transmission line attenuation and impedance mismatches. The high?speed data communication network has been designed to optimize the transmission by using a simulation model of the data distribution system which takes into account the worst?case scenario and by developing a lab?scaled prototype which exhibits BER of 10E-11 for an interfering signal of 10 Vpp. The result is a point?to?multipoint bidirectional transmission network optimized in both directions with optimal values of loads and equalization resistors. This high?speed data transmission subsystem provides a compact design through a simple solution.
