A look under the hood of the ViaSat-2 ground network

Satellites get all the press, but the ground network the Viasat team built is equally impressive. Read more in the Inside Viasat blog.


Below, see the difference between the cloud-based antenna for ViaSat-2 (left) and the larger ViaSat-1 antenna.
The building behind is full of servers and electronics for the older system; all of which isn't needed for the new Satellite Access Nodes.

"ground network the Viasat team built is equally impressive."   So impressive that others want it....

"ALCAN, Isotropic Systems and Viasat will develop high-throughput terminals to work with the mPOWER satellites being built by Boeing for SES. "    https://www.ses.com/press-release/ses-networks-announces-partnerships-groundbreaking-o3b-mpower-cust...

I couldn't tell you the underlying logic of how these beams are being lit up but I suspect it's got more to do with the network config than the actual location. This satellite has quite a few more beams than VS-1, and they're not all the same (some more powerful than others, for those 100-meg areas). All of the ground stations are built -- it's just a matter of configuring the network. Should all be done soon ...

Well I guess that answers that.  Can we see a beam map of VS2?

You're pushing your luck...  :)

"for those 100-meg areas".   I wonder how many and what it takes to be a 100meg area.

There are a number.  What does it take?  Pure speculation on my part, but from what I had seen, high utilization areas of Viasat-1.  Now THAT is a good thing.  After all, what good does a 100Mbps beam do over NYC!

Greetings to Judge and Jury. You may be a neighbor in 'these here woods.' 

Now onto SSDD gripe at Viasat. Where did the hood get put. All I see is one nice image of 2 satellite dishes. How would they fit under any hood? Behind the curtain past smoking mirrors works better. :)) Did you put the same people on this who imagined up to 12mb/sec fallacy? newest intern on this one? I've been asking why my location bounces from San Diego to Portland with some in California central valley and some in Oregon high desert. Apparently the person who might respond has been on nearly a full year break. Recently the Kenai Peninsula in Alaska and some tiny village in Northern Manitoba showed up on list of places the computer believes it has visited. Are concerns of class action certs why no response? Or is it embarrassment over the dead cat burial at crossroads on a full moon forecast? If the former you have valid concerns. If the latter, take a breath, clear your mind and forecast with a 15 percent...ummm, perhaps better to use 40 percent...margin of error/safety. I am quite sure the US government and military covered most, probably all, of Viasat2 build and launch costs with a generous over estimate clause. So the miserly .20 and less speeds are pure mean bs? Or me being a noisy customer got the response? Regardless of reason behind them it truly is no way for a service to operate. Your disclaimer on speed is not the panacea you seem to be placing such faith in. Cavalier disregard towards past, current and possibly future customers promotes ill will that translates into churn, cancelled service and in worst case hefty law suits from hungry attorneys. Much safer to promote actual conditions instead of fiction and blue sky fairly tales with a wink and smarmy smile. I must compliment your login applications although NSA and/or DARPA likely provided asic and coding to assure authorized access only.

Pretty much the story of technology, as time goes by, systems become smaller, increased processing power more robust and more reliable.  Thanks for the look.

And this is why I keep saying, the cost for Viasat 2 is more than double (possible 4x) whatever the satellite itself cost.  Lots of things on the ground have to exist for the magic to happen.
