Abstract :
The concept of the picoterminal network operating at 20/30 GHz through an Olympus type transponder has been demonstrated to support several thousand low data channels for telex traffic in an operational environment. This concept of the very small portable earth terminal can also be extended to demonstrate a voice traffic system, again through an Olympus type transponder. However an operational system would need to be supported through a much more powerful satellite such as ACTS. NASA are already studying such concepts in their PASS concept. The portable concept can be extended to fully mobile applications. However geostationary orbit configurations are a poor compromise with inclined orbit systems offering even more advantages for the 20/30 GHz mobile satellite systems than their lower frequency counterparts
