1. Number of Epochs per Day 100% expected => many gaps in the data

2. Number of GPS Observations per Day Blue: > 10 deg Red: all

3. Number of GPS Satellites in View Blue: > 10 deg Red: all Average number of satellites as expected for the location

4. Blue: 0 deg cutoff Red: 10 deg cutoff Percentage of Expected GPS Observations Percentage of observations as expected for the location; data gaps during the day are not included

5. GPS Pseudo Range Noise on L1 and L2 Pseudo range noise is as expected

6. Blue: > 10 deg and with L1&L2 Red: all Number of GLONASS Satellites in View After 15 Sep no GLONASS L2 observations

7. Blue: > 10 deg and with L1&L2 Red: all After 15 Sep no GLONASS L2 observations Number of GLONASS Observations

8. GLONASS L1&L2 Pseudo Range Noise After 15 Sep no GLONASS L2 observations; No computation of Mp1 and Mp2 possible
