Precision Analysis of CNAV Broadcast Ephemeris and Its Impact on the User Positioning
2017GPS broadcast ephemeris error is an important factor affecting the real-time positioning accuracy. Since April 2014, the IGS provided two new broadcast ephemeris products, namely LNAV (Legacy Navigation Message) and CNAV (Civil Navigation Message). Compared with LNAV, CNAV was broadcasted only on Block IIR-M and IIF satellites.
