A positional offset measurement system is provided for determining the spatial relationship between two surfaces. The surfaces may be a first surface 14 of a pipe 16 and a second surface 24 of a pipe 26. A first end assembly 12 is associated with first surface 14, and a second end assembly 22 is associated with second surface 24, wherein each end assembly is provided with at least two communication modules 20a to 20d;30a to 30d, such that signals transmitted between the first and second end assemblies by the communications modules can be used to determine the relative position of the first and second surfaces. Data signals are sent to associated data processors 11 and 21 on the end assemblies for processing. |
