Spring 2010 CEE/GLE 291 – Problem Solving Computer Tools Homework 12 FOR DISCUSSION ONLY; NOT REQUIRED TO HAND IN 1. If the average distance of a satellite in its orbit above the earth is 20,200 km, estimate the travel time, τ , of the signal to a receiver on the earth. To measure τ with a precision of 1%, what resolution of the temporal device or method is required? 2. Maude is horizontal control point in Dane County, Wisconsin; its geocentric coordinates, measured with GPS, are: X Maude = 74819.572 m Y Maude = - 4680083.182 m Z Maude = 4318564.824 m a. Use MATLAB to transform the geocentric coordinates of Maude into latitude, longitude, and ellipsoid height on NAD 83, which uses the GRS 80 ellipsoid (a = 6378137m; b = 6356752.31414m). b. From the latitude and longitude of Maude, use GEOID03, on the National Geodetic Survey website ( http://www.ngs.noaa.gov/cgi-bin/GEOID_STUFF/geoid03_prompt1.prl ), to compute the geoid height at Maude and insert it in your MATLAB worksheet. c. Using the geoid height and ellipsoid height of Maude, compute its elevation on the MATLAB
