LEC # TOPICS 1 Overview of Class (PDF) 2 Coordinate Systems (PDF) 3 Gravitational Potential (PDF) We also used some MATLAB® scripts in this lecture. The two programs are Harmonics.m, which plots low order harmonics and Sectorials.m, which plots high order sectorial harmonics. 4 Coordinate Types (PDF) 5 Satellite Orbits (PDF) The MATLAB® program to compute eccentic and true anomalies is truea.m 6 GPS Observables (PDF) 7 Specifics of GPS Signal (PDF) 8 Pseudorange Measurements (PDF) The data file displayed in class is etab.plt.dat 9 Range and Phase Data (PDF) The data files displayed in class are ASCII tab delimited files: etab.02tab, etab.07tab, etab.11tab, etab.26tab, etab.28tab (Hint: If you want to check Homework #1, then compute the range to the satellite can compare with theoretical value in the etab.xxtab files.) The site coordinates are in the rinex header shown in Lecture 8. 10 Estimation: Introduction (PDF) 11 Statistical Approach to Estimation (PDF) 12 Estimation: Correlations (PDF) The MATLAB® program fogm.m generates first-order Gauss Markov processes. (Note since the random number generator is not initialized, your results will differ from those in the class notes. Signal processing tool box is needed for the PSD calculation). 13 Estimation (PDF) 14 Propagation Medium: Propagation (PDF) 15 Propagation Medium: Neutral Atmosphere (PDF) Links used in Lecture: The Height of the Tropopause MIT GPS and Geodynamics Group: GPS Tropospheric Delay Comparisons 16 Propagation: Ionospheric Delay (PDF) 17 Basic Antenna Operation (PDF) Links used in Lecture: GPS Antenna Calibration Index of /~tah/snrprog 18 Mathematical Models in GPS (PDF) Review of assignment due dates at beginning of class. The following Fortran source code was discussed in the lecture earth_tide.f and gst_jd.f. For a complete bibliography of tidal effects see: ICET Bibliography 19 GPS Models and Processing (PDF) Models: Rank Deficiencies, Ambiguity Resolution and Differencing Methods 20 Processing Software (PDF) Links for Lecture: GAMIT GLOBK Course 21 GPS Groups/IGS (PDF) 22 Kinematic GPS (PDF) Links for Lecture: track.016f.out d016f.NEU.rovr.LC d016f.NEU.rovr.L12 23 Application Areas and GPS results (PDF - 1.1 MB)
