As In understand it the advice give civilian satellite owners/operators is offered as a 'best estimate' basis. Where the space authority will allow you to see most of the data they use and draw your own conclusions. That if a company does use advice offered by the agency they are doing so at their own risk.

Far all practical purposes the US government has the only integrated space traffic center and tracking system of any significant size.

It is my understanding this is similar to their legal status of the GPS system. The US government doesn't really guarantee accuracy or availability. It offers statistical estimates of accuracy and availability but does not guarantee either accuracy or availability at any specific time or place.

So if they suggest you move your satellite and it gets run over by an obsolete soviet satellite nobody saw coming your pretty much on your own.

Similarly if your following your GPS signal hiking or driving and you go off a cliff that is supposed to be twenty miles to the left your not going to have much legal recourse. You take the information on an as-is basis, warts and all.
