message for low signal will be issued but does not suspend antenna movement if the model is valid. The
Smart Track model will become invalid after two days with no new valid peaks.
If NORAD track is selected the operator must ensure that the system time is correctly set to UTC time. The
NORAD algorithm uses UTC to calculate the azimuth and elevation angles. The site location must also be
accurate. Significant errors may result if time and location are not correct. NORAD is intended to help find a
target. For antennas with beamwidths less than 0.25 degrees some signal loss may result from pointing
errors if NORAD is used as the primary tracking mode.
If INTELSAT track is selected the operator must ensure that the system time is correctly set to UTC time.
The INTELSAT algorithm uses UTC to calculate the azimuth and elevation angles. The site location must
also be accurate. Significant errors may result if time and location are not correct. INTELSAT is intended to
help find a target. For antennas with beamwidths less than 0.25 degrees some signal loss may result from
pointing errors if INTELSAT is used as the primary tracking mode.
The operator must switch to Not Track before selecting a different track mode, meaning that the ACS3000
will not switch from Norad Tracking directly to Smart Tracking. The operator must select the No Track first
before switching to Smart Tracking.

Satellite Table Screens
The operator may display the satellite table entries by selecting the Satellite Table button from the left control
panel. The operator can right click on the Satellite Table button in the control panel to select a special test
satellite table or to save the current satellite table to the PC. The test satellite table contains a limited
number of satellites that can be used for test purposes but is not valid for normal operation. If the test table
is loaded, the operator must update the satellite table prior to normal operation.
