Tutorial Nequick

  1. 1. TutorialExercise 1. Read the text and tell the picture about ionosphericcorrection algorithm. NeQuick is a semi-empirical model that describes spatial and temporalvariations of the ionospheric electron density. NeQuick (Fortran 77) source code is only available in its 1994 version. All of the modelsare able to createelectron densityprofiles, but amongthem NeQuick is aflexible quick-runmodel that has beenproposed for single-frequency operation inthe Galileo project tocompute the slant totalelectron content alongarbitrary ground-to-satellite ray paths.Exercise 2. Select the correct statements. Use the text ex. 1. 1. NeQuick model is a empirical model. 2. In real-time application of NeQuick for the future Galileo navigation system. 3. NeQuick model developed in FORTRAN 77. 4. In real-time application of NeQuick for the future GLONASS- K navigation system. 5. NeQuick model is a semi-empirical model. 6. NeQuick model developed in C++.
