Abstract
A downhole gyroscopic surveying tool includes a gyroscopic sensor deployed in and configured to rotate between a first rotational position and a second rotational position about an indexing axis in a downhole tool body. A non-contact detent is configured to secure the gyroscopic sensor in either the first rotational position or the second rotational position. A drive mechanism is configured to rotate the gyroscopic sensor between the first rotational position and the second rotational position and is configured to be in a non-contact engagement with the gyroscopic sensor when the gyroscopic sensor is in the first position or the second position.
