Reducing error contributions to gyroscopic measurements from a wellbore survey system |
摘要 |
A method reduces error contributions to gyroscopic measurements from a first gyroscopic sensor and a second gyroscopic sensor. The method includes receiving a first set of measurement signals and a second set of measurement signals indicative of at least one substantially perpendicular component and indicative of a substantially parallel component of the Earth's rotation. The method further includes receiving one or more measurement signals generated by a plurality of accelerometers and calculating a first and second mass unbalance offset error for the first gyroscopic sensor and the second gyroscopic sensor, respectively.
