This paper considers the algorithm of receiving and processing corrections, that included inside the signal on L6 frequency band of navigation satellite system QZSS. This signal includes corrections that provides user a possibility to realize Precise Point Positioning (PPP) mode inside receiver in real-time and get precise enough navigation solution without using corrections from base station. In this paper we are considering functionality of Centimeter Level Augmentation Service – CLAS, that supported by Japan government. In addition to precise corrections processing and decoding algorithm from QZSS L6 signal, in this paper also presented positioning  results in PPP mode using precise correction data from QZSS CLAS service. The necessary conclusions are made.
