Those are definitely repulsors, not "hovers".
It makes one wonder if those would be a good defense against warhead block torpedoes...
I'd be more excited if they would make a whole system revolving around projecting fields though.
Could lay the groundwork for universe update too, what with black holes and such.
Couldn't stars have a stronger pull up close? Just wondering. Adds another layer of tedium complexity for us to master.
Pair it with push beam - get a repulsor/attractor field (Toggled, with LMB/RMB selecting direction perhaps?)
Astrotech beam makes it a repair field, EMP - energy drain, salvage provides passive mining(?), and so on.
Size (group bonus like power caps' maybe?) of the field gens affects field size, secondaries - it's effects' strength.
Throw in a menu to customize field properties and behavior, such as affected entity types with ship it's on included, effect strength vs tick rate, and etc.
In the end you got a robust system you could, in theory, adapt to celestial bodies, stations, anomalies... Kind of a local, sub-sector scale effect application.
If there's gonna be stuff like artifacts, some weird kinds of ore, or some other sci-fi stuff with a good dose of "fi", you could add those fields to make it truly unique in some way.
