Method for data transmission via satellite by means of spread spectra and small ground stations

摘要

In this method, the spread digital binary frequencies are underlaid under other signals directly or in the transponder. Thus, data rates of less than or equal to 64 KBps can be spread by means of PN sequences and underlaid under other signals. It is also possible to transmit these spread data rates by means of ground stations, the antenna diameter of which is less than or equal to 1.8 m, via all currently available communication satellite systems.
