5 Positioning Runs

Run 1: almanac satellite position, no corrections

Run 2: add satellite polynomial clock correction

Run 3: add broadcast ephemeris satellite position

Run 4: add Earth rotation

Run 5: add ionosphere correction

Run 6: add relativity clock correction

Run 7: add troposphere model
