Integrity monitoring of NavIC by parsing broadcast ephemeris

Journal of Applied Geodesy, 2023
Abstract Global navigation satellite systems (GNSS) are used to provide position estimation to the users. These navigation systems must meet the required navigation parameters (RNP) parameters. Among them integrity being the important parameter, defined as a navigation system’s honesty of the information provided to the user by ...

Performance Evaluation of the CNAV Broadcast Ephemeris

Journal of Navigation, 2019
The new Global Positioning System (GPS) Civil Navigation Message (CNAV) has been transmitted by Block IIR-M and Block IIF satellites since April 2014, both on the L2C and L5 signals. Compared to the Legacy Navigation Message (LNAV), the CNAV message provides six additional parameters (two orbit parameters and four Inter-Signal Correction (ISC ...

Computing satellite velocity using the broadcast ephemeris

GPS Solutions, 2004
GPS has been used for applications where satellite velocities are needed as well as satellite positions. Traditionally, the position was determined from noisy code pseudoranges while the velocity came from delta carrier phase measurements. This motivates the need to have a velocity model to accompany the velocity data.
