Abstract
A survey tool includes a gyroscope and an accelerometer. The gyroscope can include a multi-axis gyroscope, a reciprocating gyroscope, or a combination thereof. The survey tool is independently rotatable relative to an outer housing and collects gyroscopic measurements and accelerometer measurements during drilling activities. Using the gyroscopic measurements and the accelerometer measurements, the survey tool calculates earth rate components of the rotation of the earth. Using the earth rate components, the survey tool determines the azimuth of the downhole tool.
