Artificial gravity created by the grav plates is a separate system to the acceleration compensation. They are more than likely based on similar principles - both applications of magic gravitics technology.

Artificial gravity appears to be limited to 1g in CT sources, while acceleration compensation has to be capable of coping with the full maneuver capability of the ship.

Also note that artificial gravity is not the same as real, so there is the possibility that the grav modules used on grav belts will not work in an artificial gravitic environment...

To elucidate, a ship's "artificial gravity" can not be the same force as a planet's "natural" gravity. They obey different rules.

Actual gravity is unlimited in range and omnidirectional but decreases in intensity as it goes. You just can't tell the difference between 4000 miles and 4000 miles and 6 feet.

"Artificial gravity" is limited in range and directional but constant in intensity. Grav plates pull down only in one direction only rather than in a sphere but are constant in pull over their range (which stops more or less at the ceiling).

As Rupert indicated, an artificial gravity negator is conceptually possible but not directly related to anything that overcomes natural gravity.

Ah, but check out what gravity does over a disk, especially one of infinite size (or even very large size). This 'allows' such interesing things as Alderson Disks.

I'm sure there are interesting things about the concept but they do not seem to be well explained in that link. Indeed it did not seem to say anything about what gravity in/on such a structure would be like.

Anyone who even semi-regularly forces entry into spaceships with artificial gravity will have them. If everybody can have grav plates, everybody can have anti- grav plate gizmos.

Militaries will have them, pirates will have them, salvage crews will have them (to counter malfunctioning plates in wrecks), ships engineering departments would have them (to work on their own malfunctioning plates) law enforcement will have them.

If you can build a device to mimic gravity’s effect on an object you can build a device to interfere or counter with that effect. Hostile environment suits would probably have it as a standard option.

That doesn't necessarily follow.

Not when a basic 'let's you fly' grav belt is ~100K, and the standard vacc suit is a few KCr.

As for your own engineering needing them - they can just turn the plates off.

But if you want grav pong to not be a thing, sure, make full-sphere instant reacting anti-gravity that works on grav plates cheap and freely available. If your players are like mine they'll find a dozen ways to wreck the game world and economy before breakfast, even with perpetual motion devices banned.

While this is true, in a setting where any ship you might board has remote control death fields available, you're either not going to engage in boarding actions, or you're going to have way of dealing with those remote control death fields.

The one I usually see is 'fry the plates before you stand on them'. It's unsubtle and it's slow, but it's sure.
