persistent, the next MCU status message will reset the fault.

The Save Current Position as Peaked button allows the operator to save the current position in the s atellite

table as the peaked position of the base satellite. All three axes – az, el, and pol – are saved and will be

used when the operator selects a satellite and moves to that satellite. The select/move to satellite butt on on

this screen will move to the satellite selected in the pull down window. Only satellites that have sa ved

peaked positions will be listed in the pull down window. The saved peak position will also be used for the

position to move to when the operator selects a new base satellite from the satellite table scr een.

The Download Position Log to Local Drive button will allow the operator to copy the position log fr om the

ACS3000 server down to a local drive on the PC. The file will be saved as C:\ACS3000\ antennaID\

position.log.

The Jog with Arrow Keys panel allows the operator to enable and disable the arrow keys to contr ol az and el

The antenna position, beacon level, and UTC time display are provided to show the operator the curr ent

antenna status. The antenna position (azimuth, elevation, and polarization) are updated e very 200

milliseconds. The beacon level is updated every 400 milliseconds. The time display is updated e very second.
