The present invention overcomes the disadvantages of the related art by providing a spatial reference system that includes at least one artifact assembly. The artifact assembly has a measuring bar assembly including an inner member with a proximate end and a distal end, an outer member with a proximate end and a distal end, and a compensating member with a proximate end and a distal end operatively disposed between said inner and said outer members. The distal end of the outer member is fixedly mounted to the distal end of the compensating member. The proximate end of the compensating member is fixedly mounted to the proximate end of the inner member. The inner and the outer members each have a predetermined length and a predetermined coefficient of thermal expansion and the compensating member has a predetermined length and a predetermined coefficient of thermal expansion, such that the thermal expansion of the inner and the outer members is substantially eliminated by the expansion of the compensating member.

Spatial reference system

A method and an assembly for determining the presence of gaps located between a first portion of a partially assembled apparatus and a second portion . The existence and size of the gap may be discerned by use of a wireless gap sensor which is engaged by the portion as it abuts or comes into close proximity with the portion . Other methods and may be respectively used to respectively discern the existence and the size of a gap within an assembled vehicle and to measure the deflection of a portion of an apparatus, such as a vehicle.

Methods for determining the existence and the size of a gap and for determining the amount by which a portion of an assembly deflects
