Remote sensing satellites orbit around the Earth around 600-900 kilometers in sun synchronous polar orbit. Each satellite transmits the image data in X-band and the data reception is carried out through a parabolic antenna along with the associated systems. The entire data acquisition system is complex and expensive as it has to meet the requirements of the(More)
With the advent of high bit Giga bit network, it is easy to access any system/network globally. The development of reconfigurable and field up gradable logic devices enabling the digital system designs to opt for the development of built-in testability, diagnoisabilty of the devices with an application of remote management as the basic feature. The timing(More)
Remote sensing satellites are of the class of LEO and hence visible to any ground station for a short period of time around 5 to 15 minutes in a given orbit. They also move with velocities greater than 6 to 8 km/sec. The azimuth velocity is a function of CosEL and hence as the elevation angle approaches 90deg (>87.5deg) the velocity requirements cross(More)
