Downhole tool sensor arrangements and associated methods and systems

A downhole sensor system comprising:

• a sensor structure disposed on a downhole apparatus, the sensor structure positioned a distance from a central axis of the downhole apparatus;
• at least two sensors positioned on the sensor structure, the at least two sensors having at least two axes of measurement, the at least two sensors comprising:
• a first sensor in a first position;
• and
• a second sensor in a second position, wherein a first axis of the second sensor is substantially coaxial with a first axis of the first sensor and a second axis of the second sensor is parallel to and offset from a second corresponding axis of the first sensor;
• and
• at least one processor;
• and
• at least one non-transitory computer-readable storage medium storing instructions thereon that, when executed by the at least one processor, cause the processor to:
• measure a first acceleration from the first sensor;
• measure a second acceleration from the second sensor;
• and
• calculate acceleration properties of the downhole sensor system based on acceleration measurements of the first sensor and the second sensor.

A method of calculating acceleration properties of a downhole tool, the method comprising:

• synchronizing a first accelerometer and a second accelerometer;
• measuring a first acceleration from the first accelerometer about at least two axes;
• measuring a second acceleration from the second accelerometer about at least two axes, wherein a first axis of the at least two axes of the second accelerometer is coaxial with a first axis of the at least two axes of the first accelerometer and a second axis of the at least two axes of the second accelerometer is parallel to and offset from a second corresponding axis of the at least two axes of the first accelerometer;
• and
• calculating the acceleration properties of the downhole tool based on acceleration measurements of the first accelerometer and the second accelerometer, wherein the acceleration properties include an angular acceleration and a lateral acceleration.
