A Method of High-precision Angle Measurement Using Carrier Aided by PRN Code

  • The problem of high-precision angle measurement based on short baseline is analyzed.In order to obtain high-precision angle measurement in real time under the condition of limited baseline length,high frequency carrier is used and the carrier-cycle needs to be accurately calculated.A method of high-precision angle measurement using carrier aided by PRN (pseudo-random noise) code is proposed to resolve this problem.With the help of the rough measurement results provided by PRN code,the high-precision angle measurement can be implemented by utilizing carrier.The condition of carrier-cycle un-ambiguity and the rule of carrier-cycle resolution are given.The proposed method can resolve the carrier-cycle in real time and the choice of the carrier frequency is not constrained by the length of the baseline.
