Simple mathematical model We know examine as series of results based on the results you are generating for homework #f1 and the rinex data collected at the time How closely can the observed ranges and phases be matched with a simple calculation? Simplest calculation: At the time given in the rinex data files, compute the position of satellite and based on rinex header position compute the range. How accurate is this? 03/06/02 12.540Lec09
