Abstract

The results of creation and research of the new effective method for processing of the double–frequency kinematics GNSS observations with the purpose of detection, estimation and repair of carrier phase cycle slips are presented. This method is based on the use of observations’ increases at times and the special procedure of the joint least–squares method estimation of aggregate of informative (increases of coordinates and divergences of clock) and uninformative parameters (carrier phase cycle slips). The estimation of carrier phase cycle slips is carried out by direct enumeration in a preliminary determined search area. Verification of the offered method is carried out with the use of simulation and the real GNSS observations. Shown that reliable determine and repair of carrier phase cycle slips in the consider case is achieve at the complete or partial loss of observations on the intervals up to 20 s.
