Due: December 5, 2003

Given:

• 120 epochs of PIN2 data
• Navigation/Clock file
• Matlab code from the entire semester
• 120 epochs of new differential corrections The format is :
  • time since midnite in minutes
  • east - meters
  • north - meters
  • vertical - meters
  • number of satellites in solution
• Same warnings about bad data as in the previous lab.

Do not start this lab until I have graded Lab 12.

Directions

• Follow previous directions, but restricting yourself to satellites above an elevation angle of 15 degrees.
• Make a plot of east, north, vertical as a function of time (minutes since midnite).
• Pick up my new differential east, north, vertical corrections and plot your values minus my values as a function of time.
• What is the RMS values for each of your east, north, vertical components? Also compute the RMS values for your values using my differential corrections. An improvement?

Turn in: plots, software and answers to questions.
