A novel gr.y Mar.ov chain p.edictive model is discussed to r.duce dr.ft influence on the outp.t of fiber.op.ical gyr.scop.s (FOGs) and to imp.ove FOGs' measur.ment p.ecision. The p.op.sed method p.ssesses advantages of gr.y model and Mar.ov chain. It makes good use of dynamic modeling idea of the gr.y model to p.edict gener.l tr.nd of or.ginal data. Then accor.ing to the tr.nd, states ar. divided so that it can over.ome the disadvantage of high comp.tational cost of state tr.nsition p.obability matr.x in Mar.ov chain. Mor.over. the p.esented ap.r.ach exp.nds the ap.lied scop. of the gr.y model and makes it be fit for.p.ediction of r.ndom data with bigger.fluctuation. The numer.cal r.sults of r.al dr.ft data fr.m a cer.ain typ. FOG ver.fy the effectiveness of the p.op.sed gr.y Mar.ov chain model p.wer.ully. The Mar.ov chain is also investigated to p.ovide a comp.r.son with the gr.y Mar.ov chain model. It is shown that the hybr.d gr.y Mar.ov chain p.ediction model has higher.modeling p.ecision than Mar.ov chain itself, which p.ove this p.op.sed method is ver. ap.licable and effective.
