DOP level setting (estimated precision)
Fig.18. NAVIA G GPS application 1PPS signal level window tab.
This tab defines DOP (estimated Dilution of Precision caused by satellite position
interference) start and current operation levels threshold.
If the satellite position geometry weakens and the DOP value (PDOP, VDOP, HDOP,
GDOP) exceeds the threshold, the navigation solution is treated incorrect (invalid).
ST-AGPS mode
Fig.19. NAVIA G GPS application 1PPS signal level window tab.
This tab allows to switch on and off satellite layout prediction functionality (Self Predicted
ST-AGPS). This tab also indicates calculations status (either prediction calculation completed or
not) and predicted data time for each of the satellites used in estimation. In case of actual current
prediction all satellites would have data time equal to 0 days and would not be shown on the
graph.
