We switched 2 months ago from geo stationary VSAT to inclined orbit.  We have Vertex 4.8m to IS-603.  It worked flawlessly for 2 months and then 3 times in last 8 days at 0230 GMT the link dropped.  It was always the tracking.  the screen on Antennae controller looks as if it is in manual mode, but the auto light was lit.

Anyone have experience where we should be looking.  I doubt it is power as it is on UPS running off batteries .  Other servers on same UPS had no issues.  Unfortunately i dont have exact what was on screen.

I am assuming you have set the appropriate gain on your beacon monitor?  Have you been able to observe the monitor at the time the unit tracks off?  I guess I am assuming you are tracking via beacon, I will wait for your reply before commenting further.

See if you can access the antenna tracking controller log file to see what has been happening over the past few days and details of exactly what was recorded prior to and at the time of the outage.

It can be worth spending some time analysing the log file to plot by hand where the antenna moved and try to work out why.

Best regards, Eric.

Hi,

What tracker do you use?
Where is your location and which bird are you (trying) to track?

Kind regards,
Nimrod
