Title:
A DIGITAL SATELLITE LOCATING METHOD USING SATELLITE SPECTRUM
Document Type and Number:
WIPO Patent Application WO/2009/021438
Kind Code:
A1
Abstract:
A digital satellite locating method using satellite spectrum includes the following
steps: 1) pre-storing the needed satellite spectrum in a storage unit of a system;
2) calling out the pre-stored satellite spectrum from the storage unit when searching
satellite, and comparing the currently measured satellite spectrum with the
pre-stored satellite spectrum when adjusting a satellite antenna; 3) if the
measured satellite spectrum is gradually approaching to the curve of the pre-stored
satellite spectrum, declaring that the satellite antenna is going to gradually
align with the satellite; 4) when the two satellite spectrum above stated are
nearly same, the system judges the locking of the digital signal, and when the
digital satellite signal is locked, displaying the finding of the needed digital
satellite.
