A multi-dimensional cycle hop detection algorithm based on smartphone phase
Constrained by the performance of the built-in low-cost linear polarized antenna of smart phones,the original GNSS carrier phase observations have a very high proportion of cycle hop observations,which brings challenges to the precise positioning of smart phones.In order to make effective use of phase observations,based on the traditional TDCP cycle jump detection al-gorithm,this paper proposes a multi-dimensional cycle jump detection method for smart phone original phase observations with additional prior and post constraints.Experimental results show that this method can effectively mark the cycle hop information of phase observations,and the RMS of smart phone real-time PPP solution is less than 2.5m under urban comprehensive road conditions,which fully verifies the effectiveness of the cycle hop detection algorithm in this pa-per.
