The IBR-L7 is designed to be fitted integral to the INTRAC range of antenna controllers, it is tuned to the nominal down converted L-Band beacon signal by the INTRAC. The frequency may be set from the INTRAC front panel or from a remote control terminal.
The receiver is a high performance FFT based unit that searches a range 80kHz either side of the nominal frequency for the largest signal in a 3kHz resolution bandwidth. It continuously measures the level of that signal and passes it to the INTRAC unit as an analogue voltage. Lock time is under 1 second.
The INTRAC, in conjunction with the IBR-L7, uses sophisticated measuring techniques to track the satellite using the beacon level information. The IBR-L7 unit is digitally controlled using advanced algorithms which ensure that the receiver locks rapidly and reliably onto the main beacon.
The unit can be used to replace the earlier IBR-L5 in INTRAC controllers.
