Satellite Internet. Organization of a data transmission channel in a place where "everything is bad" with internet

There is a place on the outskirts of the Dnepropetrovsk region. (Ukraine). It is necessary to organize a data transmission channel there. Main tasks:
- web surfing, mail
- terminal access for several users to the terminal server from 1c from outside.

Everything is bad with the Internet: DSL is absent, 3G does not take any (you really need to try with amplifiers and antennas). More or less, EDGE from Kyivstar does not work badly.

Is there an idea to organize the Internet there via satellite?
Are there people who use satellite internet? How stable is the channel and how are things with pings (it's still critical for the terminal)?

* cheap options require a control channel (aka outgoing), in this case the satellite is used to receive incoming traffic, it will not work for terminals
* there are stand-alone options that are more expensive, a few years ago, when studying the issue, the price level was from $ 100k, now you can’t find it right away could, but the speeds should still be inadequately low ...
ps pings in any case should be around 400ms and higher, since satellites are used in geostationary orbit, and this is 36t.km (the speed of light is 299t.km / s) i.e. even in the ideal case, only the transmission costs in one direction are 120ms, plus a low frequency - 1 MHz, plus a common channel, plus the weather, plus impudence ...

You can try this: www.satgate.net/services/slonax
But I don't know how it will be with the terminal, maybe bad...

At a time when ADSL cost us about 1.9 rubles / MB, satellite Internet was not such a bad option. It made it possible to get prices of the order of 1 rub / Mb during the day and about 0.6 rubles at night at a speed of 1 Mb (despite the fact that then ADSL on our ATS was started at 4-5 Mb). We used this same ADSL as a reverse channel. All equipment (Supral 1.2m, head with linear polarization, DVB-card SkyStar 3 aka TT S-1401) cost us ~6.5 kilorubles. Any proxy with compression such as globax or the above-mentioned slonax really allows you to speed up page loading when surfing. If you have access to a server on a good channel, I advise you to look towards ziproxy.
All this I mean is that if the matter is completely rubbish, then the “basin” is quite an option. But yes, there are problems with the terminal. Pings are about 400-600 ms.
