When Viasat 2 is up and running for use, will the latency times be improved any? I’m guessing no because the satellite is still a satellite but one can hope (:

AlexDupree, the latency will be about the same with Viasat2 as it is with all the satellites. They are 22,500 miles in space, and physics cannot be changed by technology. The only way to reduce the latency is to go with ground based service, or wait, maybe forever, for a company to invest billions to launch thousands of low level satellites a few hundred miles above the earth.
Low orbit satellites are already being launched. Several up there now.
And Airborne is trying to launch an ISP system using commercial airliners. http://www.satellitetoday.com/telecom/2017/02/08/company-plans-turn-airplanes-communications-satelli...
Elon Musk has plans to start an ISP called Starlink. These will be low orbital satellites with ping that rivals cable. The download speeds will also be fairly high from what I have read, which is around 1 gigabit per second. This however, will not be out so soon. Estimated to be operational around 2024.
It's coming, called oneweb
They evaluate how to use the laser links to provide a network and look at the problem of routing on this network. They conclude the SpaceX Starlink network can provide lower latency communications than any possible terrestrial optical fiber network for communications over distances greater than about 3000 kilometers.
And what about maybe adding a signal amplifier to the outgoing signal from the residents satellite?

Confirming with the above replies. The satellite is going to be several miles up in space so we're still looking at about 700 m/s latency with the service. That will always be an Achilles heel for the technology.
if viasat could partner with a wireless company for sending and recieving web requests through cell then pushing the data through the sat that could speed things up a little. at least to 350-400 ms.
Yep. That is how Direcpc worked. And it worked really Well! I used it for about a decade until Hughesnet phased it out for the two way system.

JSam must think that all of us out in the boonies have cell service at home. What a dreamer.
There's a few things that can be done about latency but not on viasats end
While there are a number of things that can be done to minimize the impact of latency (some of it is alread done by Viasat), there is nothing that can be done about inherent latency short of replealing the laws of physics or increasing the speed of light.

Ron, tell me how you think that the laws of physics can be overridden. I am very interested.
Flux capacitor and Mr. Fusion... we don't need an Internet super highway where we're going...

Maybe Ron means physically moving closer, like the moon. They have reduced the amount of latency over the last few years using technology beyond me, but I think we are close to the theoretical maximum.
I speed up light once in a college lab, but misplaced my work unfortunately.

I made cold fusion work too, but that was while staying at a Holiday Inn Express and I left forgetting the formula.

Move to a mountain, and suddenly your latency will be reduced.
Use an Ansible. Problem solved.
This is an uncontroversial comment but yet it's brought controversy. How does one change the laws of physics? That is an incredibly stupid question. You can not change the laws of physics but you can manipulate your physical world. They did so in the first cloud gaming services. They didn't move mountains. There are again a few things that can be done but not on viasats end.
Light does move slower in a medium other than a vacuum. So if one has a vacuum chamber in the lab, they can move light faster than that of a flashlight in the air. (grin)

Space is a vacuum.
In space... no one can hear you scream.
