Satellite receiver and acquisiton system

A control means for a satellite receiving system

• comprising means for storing a plurality of setups each defining a complete set of parameters necessary for acquiring any one of a plurality of transponders on any one of a plurality of satellites,
• means for defining all of said parameters for each setup, and
• means for at will, selectively calling forth a setup for a specific transponder of a specific satellite and for transmitting control signals to external means to cause such satellite and transponder to be acquired, and
• input control means for defining information for each of a plurality of satellite-transponders desired to be acquired including satellite position, C or Ku band operation, transponder frequency, video and audio IF frequencies, half or full transponder operation in Ku band, video normal or reverse,
• means for storing a plurality of setups each including such information for each satellite-transponder pair, and
• means for calling forth each such setup and for generating signals for use by associated equipment to acquire the desired satellite-transponder and frequencies.

A satellite receiving means with control means comprising,

• means to control polarization of signals to be received by said receiver,
• a mixer,
• a mixer means supplying said signals to said mixer,
• a local oscillator to supply signals to said mixer,
• a phase locked loop including a microprocessor for controlling the approximate frequency of said local oscillator to produce an IF signal from a received signal,
• an automatic frequency control feedback to said microprocessor to fine tune said local oscillator,
• said control means having means for defining and supplying to said microprocessor the frequency and polarization of the signals to be received,
• said control means further including,
• means for defining transponder-half transponder Ku band operation,
• automatic video level control means, and
• means for activating said automatic video level control means operation.
