A downhole sensor system may include at least two accelerometers having at least two axes of measurement. The at least two accelerometers may include a first accelerometer in a first position and a second accelerometer in a second position. A first axis of the second accelerometer may be substantially coaxial with a first axis of the first accelerometer and a second axis of the second accelerometer may be parallel to and offset from a second corresponding axis of the first accelerometer. The downhole sensor system may further include 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 may cause the processor to measure a first acceleration from the first accelerometer and measure a second acceleration from the second accelerometer. When executed by the at least one processor the instructions may also cause the processor to calculate acceleration properties of the downhole sensor system based on acceleration measurements of the first accelerometer and the second accelerometer.
