Helo INS wanderings
Chaps,
Just a general inquiry. For those of you who have aircraft fitted with an INS available for use as a navigation tool, what kind of accuracy over time are you getting? Anecdotally I've heard of a laser ring system wandering around 1nm per hour in a rotary platform. Is that typical in actual usage or are modern systems (without the aid of gps) getting better than that?
Cheers!
