Patent ID: 6923059

Claim:
An angular motion measurement system disposed on a movable platform having a first section and a second section, comprising: (a) a first measurement arrangement configured to provide a first output indicative of angular motion of the first section, said first measurement arrangement having a bandwidth above 50 Hertz and at least one of, a bias above 5 degrees per second and a scale factor above 10%; (b) a second measurement arrangement configured to provide a second output indicative of angular motion of the second section, said second measurement arrangement having a bandwidth below 50 Hertz, a bias below 5 degrees per second and a scale factor below 10%; and (c) a processor arrangement responsive to a plurality of inputs, which include said first output and said second output, generating a corrected output having a bandwidth above 50 Hertz, a bias below 5 degrees per second and a scale factor below 10%.
