Title: Help please on Monopulse tracking
Post by satnew on May 29^th, 2012 at 7:12am

Dear All,

Does anyone have a detailed procedure to perform a monopulse tacking using Vertex ACU model 133?
1. I was able to point at the satellite successfully, performed step tracking.
2. I have the ephemeris table of the satellite and can do Optrack, charge using the ephemeris table.
Problem comes when performing monopulse tracking. The antenna just keeps moving away from the bore sight.
Antenna is 13m.

Thanks

For the operations and maintenance manual go here:

and email them asking for the manual, advice, and help.

It is perhaps worth checking that the antenna feed is a monopulse design, with multiple LNAs.

Best regards, Eric.
