In order to save storage space and improve transport efficiency from huge of dynamic data of TTC ship-borne trajectory measurement equipment,the ship-borne central computer must reprocess and compress the data.An algorithm based on polynomial fitting for real-time trajectory data compression is proposed in this paper.A series of orthogonal polynomial basis are presented and the smoother formula of output point with the least square filtering is applied.When the truncation error and random error are considered simultaneously,the best filter is obtained.Computational results show the novel algorithm is a promised compression and noise filtering method.
