How would the Loroi Army invade a planet?

[Ithekro]

Unlike any war on Earth, the Loroi have space superiority. Unlike air power or missiles directed by satellites, which are not always overhead, a few starships in orbit can fire on any target, anywhere on the planet at a moments notice. And they are the eyes of the invasion in addition to them being the air support and artillery. Its like having an offshore battleship with a observation drone you can't shoot down, and the "shells" will arrive about a second after the gunner pulls the trigger. Anywhere on the planet.

Starships aren't usually overhead all the time as well, except when in geostationary orbit. Which can be achieved by satellites as well.

Our satellites, by treaty, are not armed. If you are going for space superiority, you either park enough ships in orbit to always have someone overhead of any given place on the planet, or you park fewer ships in high geostationary orbits to have coverage of the entire planet.

The point wasn't about the satellites. It was about the missiles and air power. Those take time to get places on this planet. An orbiting starship is already there, and just needs a target to lance with its laser autocannons from significantly less than a light-second away.

Functionally, they don't even need to be powerful ships. Destroyers and escort cruisers have more than enough autocannons for orbital fire support, and anti-missile systems to deal with any remaining planet bases missiles.

I wonder what would happen to the modern world if all our satellites were suddenly destroyed?

Anything reliant on satellite GPS to function would be severely hampered. And anything reliant on satellite imagery would effectively be blinded to anything new since the last good image was received. Granted here in the US we have planes that do flyovers of the country for ARCGIS imagery, but that's not done daily.

Plus global comms would be hampered to some degree as satellites are a chokepoint for some systems, and if not immediately able to replace them, we'd have to somehow shunt those comms to things like troposcatters and other long range RF systems. Those have their own limitations and vulnerabilities, so good luck maintaining them against forces that can knock out satellites.

So as far as communications we'd be partially setback to the 1950's.

Its more like the global network would be significantly disrupted and then would eventually recover in a lessened form. There is hardly anywhere that can only be reached by satellite (there are plenty of undersea cables), but satellites are part of the network. Various routing tables would presumably take a while to recover but most likely no more than a few days, biggest issue would be there would be insufficient capacity for everyone's customary level of internet usage if you are trying to reach a site on the other side of the world. Minding if you are actively being bombed by aliens in orbit then that puts a bit of a damper on commercial internet use anyhow.

I remember when there where some "in case of war" pages in the phonebooks. One very specific order where that ANY order to surrender should be considered false, such as the enemy pretending to be our officals. Effectively it would mean it would be impossible for the swedish leadership to communicate a surrender to the people since such communications as of earlier orders where to be considered false.

My own take on the "get to the leadership" thing is that once someone being compromised that person instantly loose all authority. As such it would, for example be physically impossible to keep an enemy president in custody on the grounds that said person would cease to be the president once captured.
