An assembly of single-component motion sensors consists of four equinumerous groups of sensors. All the sensors in any one group have their measurement axes parallel and the directions of the measurement axes of the four groups are parallel to the diagonals of a rectangular parallelepiped. The edges of the imaginary parallelepiped are parallel to the coordinate axes relative to which it is desired to measure the components of motion. With two sensors per group the assembly can still give results after any two sensors have failed. It is shown how two non-simultaneous failures, and, in some cases, two simultaneous failures, can be located.
