GNSS Receiver Raw Data Analysis view

The Raw Data Analysis view numerically displays the results of the raw data analysis. Use it to view the current status of the last epoch and to easily detect data slips or high ionospheric scintillation values.

Above the list of satellites - see its contents in the table below -, the view displays the date and time of the last epoch and its current status. Possible states are:

Epoch ok
Epoch data bad
Too many satellites
Bad single point position *
Bad code carrier consistency

* If this status message occurs, consider checking the station's position information.

Available columns in the list of satellites:

Column header	Description
Sat	Satellite System and PRN number.
Cycle Slips	Occurrences of unresolved cycles slips during the tracking time.
Bad Data	Epochs that are marked "BAD" during the tracking time.
Tracked Since	Tracking date and time since this satellite was first tracked. *
OK Since	No error reported for this satellite since x seconds, since this satellite was first tracked. *
Scintillation Index	Index value of ionospheric scintillation. This is an indicator of the current ionospheric activity given at a station. Index values are between 0 (no activity) and 10 (highest scintillation activity).
Status	Status of error, according to the following list.

* If a satellite was not tracked anymore for more than 3600 seconds, these values are reset to zero.

The Status column may display one of these messages

Note - The update interval of the status messages depends on the bandwidth control setting you have selected when logging in to the Trimble 4D Control Server UI.
