A Typical System 
The antenna position resolvers provide direction information 
to the INTRAC.  The IBR-L (beacon receiver) provides 
tracking signal strength. (A signal strength derived dc voltage 
from an external receiver may be used in place of the 
Advantech AMT IBR-L) 
The Motor Drive Cabinet receives the antenna drive 
commands from the INTRAC and drives the azimuth, 
elevation and polarisation (option) motors and brake 
assemblies. 
Limit switches on the antenna prevent it from being moved 
beyond mechanically defined positions. 
The INTRAC-305 may be controlled from its front panel or 
from an optional PC based Remote Control and Monitoring 
Terminal. 
Retro Fitting    Existing Step Track or Program Track installations may be 
updated to INTRAC systems.  Advantech AMT Ltd. have 
considerable experience of retro fitting INTRAC systems.
