Download ISTA rinex data and sp3 precise ephemeris files for relevant days for every student according to the dates on Table 1. For epochs of 00.00, 06:00, 12:00, 18:00 from rinex data of that day: Only the GPS satellite observations will be used to calculate the receiver's coordinate by using the C code and P code measurements for each epoch separately.

In addition, 4 different epochs will be adjusted together for the C code and the P code observations. The 3D positioning error, the standard error of the unit-weighted measure and PDOP value should be calculated.

DATE OF RINEX (ISTA): 02.01.2021

Mathematical Presentation. X= The calculation part included in the matrices used in adjustment, the coordinate of the receiver with the control of adjustment, v corrections, correcteddistances, positioning error and PDOP value should be given. Graphical Presentation. A graph including 3D position standard deviations and PDOP values for P code and C code should be submitted. (Graph will contain the solution of the 00:00:00, 06:00:00,12:00:00,18:00:00 values.) Mathematical Presentation.
