Autonomous Orbit Control for GEO Satellites

It has been rather disappointing to note that some 20 years after we had worked on autonomous orbit control of satellites using position and velocity control, autonomous control has still not found application in the geostationary communication satellite world. With the current trend in GPS and propulsion technology, perhaps it is time to take a serious look into the possibility of applying this technique using continuous position and feedback control…

Specifying Antennas

This brief monograph attempts to list the parameters that may be specified for an antenna. The list also has brief explanations of each parameter.

No. Parameter Description
