Publication number: 20090315760Abstract: A hybrid control algorithm for low profile phased-array antennas, consisting of a gyro control and electronic beam-forming, operates to track the satellite. The antenna arrangements form a spatial phased-array capable of being rotated mechanically both in azimuth and elevation planes by the aid of step motors. An RF detector monitors the received RF power and provides a feedback signal to the control algorithm. Based on the monitored signals, provided by RF detector and gyros, the processing unit operates, under suitable algorithms, to home on and track the desired satellite. The arrangements can be mounted on a vehicle to provide TV and broadband internet signal to the user on the move.Type: ApplicationFiled: May 30, 2008Publication date: December 24, 2009Inventors: Seyed Pedram Mousavi Bafrooei, Seyed Hamidreza Jamali, Mohammad Fakharzadeh Jahromi, Kiarash Narimani, Mircea Hossu, Hamidreza Bolandhemmat, Safieldin Safavi-Naieni
