The underground o il and gas pipe lines, espec ially the p ipe-

lines under thew ate r, need steady or per iodicOunsteady positioninspection. The trad itiona l m ethod is carr ied out w ith GPS and

detected appa ratus, wh ich results in huge w ork load and h igh

costs, what is mo re, it could no t reach an expected prec is ion.

An or ientation pro jec t based on inertial dev ice w as introduced in

the paper. The inform a tion of position w as stored in the co llec-

therefo re, it increases the system s' re liability and definite ly de-
