Alberding-QC (AQC) is a flexible configurable software designed for quality control of DGNSS, RTK
and PPP services. AQC consists of the Checkstream, RTK-Check and InspectRTCM modules,
which can be used individually or together to monitor GNSS services.
In order to determine data stream availability, Checkstream connects as a user from an external server
to the GNSS service at definable intervals. Current status information and the history over definable
time periods are clearly displayed in a colour-coded status table. During the analysis, a distinction
can be made between availability during normal working hours and complete availability (24/7).
In order to check the initialisation times and accuracies, RTK-Check connects as a user to the GNSS
service at definable intervals, forwards the correction data to a GNSS rover and determines the
initialisation time and the accuracy achieved with respect to the reference value. The data is presented
clearly in tabular form and in graphical time series. The use of external RTK and PPP algorithms is supported.
In order to detect data format problems, InspectRTCM converts binary RTCM correction data into an ASCII-readable
data format. The readable data format provides information about the message types contained in the correction
data stream and their repetition rate. InspectRTCM helps to solve incompatibilities between RTK sensors with
RTK services and to check the continuity of messages.
Configuration and monitoring via a single web interface.
