Track data creation for continuous wellbore survey algorithm simulation

To achieve the fast and precise survey goal, a dynamically tuned-gyro based continuous survey system was suggested. Wellbore track data and inertial components outputs are needed when continuous wellbore survey algorithms are simulated. Flight track data creation method was extended to the wellbore survey field, a track data generator was designed and the inertial component models were built, so simulation inputs were provided. The track data generator bases on inertial navigation principles, and creates inertial components outputs by mathematic method. The strapdown inertial attitude algorithm simulation results verify its effectiveness.
