I've been sent some pictures of the various items that comprise this GATR antenna system for sale.  Below each image I have tried to identify what the items are.  If you need clarification please  email me eric@satsig.net and I will pass the message on to the present owner.

Finally, I wondered what a GATR antennas looked like when deployed.  Here is the result of a Google image search for GATR antennas:

the last couple of days I have been making a calculator to work out speed and period for a satellite at a given height.

Here it is: https://www.satsig.net/orbit-research/orbit-height-and-speed.htm

I have tested it a few times against known data and it seems to work, but I would appreciate someone else testing it and identifycing any problems or errors.

Best regards, Eric

We are looking for 50 to 100 units low cost used HX90 or HX50 modem and 2W transmitter. Also need the license to register the units in the hub.

More information, mail to turresty@hotmail.com

Yesterday I updated the page mentioned above to show the 70 deg elevation contour and added a new page with polarisation / skew angles.

All this kit is still for sale.


View of the motorised Direcway antenna.

If you are interested in buying these parts please email me eric@satsig.net quoting reference "27/03/2020, 18:15" and I will forward your email to the seller.

The motorised Hughes Direcway dish is located Hurst, TX 76053.

If you are interested please email me eric@satsig.net and I will put you in touch with the owner.  All offers considered.

This would make good project for tech students !

Best regards, Eric.

Can anyone recommend a BSS Billing Solution that has integrated well with Avanti OSS Newtec hub.

This picture below gives you an idea of how a satellite might move during the day.

The actual movement may be an ellipse and it may drift sideways slowly over a week or so. The view shown applies if you are on the same longitude as the satellite longitude. Elsewhere, the equator line will be tilted relative to your local ground horizon.

Ideally you want to aim a fixed dish at the centre of the intended stationkeeping box so that the satellite does not move too far from your beam centre.  If you call the satellite network operations centre they can tell you when the satellite is due to cross the equator, twice per day.  The east west position is more difficult as the satellite might drift sideways through the middle longitude less frequently, like weekly or longer.

Read more here: Inclined orbit operation

If your dish is large enough that the -1 dB beamwidth is the same (or smaller) than the stationkeeping box then you need to point a fixed dish very accurately and tolerate twice daily peak degradations. 

Useful Antenna beamwidth calculator

I have made a new page today that should hopefully show views of the world with elevation contours for geo satellite orbit positions..
Example:



Please say if you can suggest anything.

Go here: Geostationary satellite elevation map
to choose your own orbit position and also animation possibility for fun..

Best regards, Eric.

Could you please share with me how to interpret centre of box information. I have been given the task to select an appropriate time for the re-alignment of 6.3m antenna to the satellite and the satellite operator has shared with me the COB. I'm still learning. I await your kind feedback.

The antennas are still standing at New Era Systems teleport in South Florida and offers the new owner a chance to inspect while in working operation. Please note that the prices do not include take-down and packing. We can offer those services for an additional cost.
