Further control elements implement loops which repeat sequences for a number of
repetitions ("for"-loop) or while there is enough data left ("while"-loop).
Control elements can also contain references to previous elements, that is: to results
obtained in previous instruction steps. References are defined using the element's
unique identifier, which is a mandatory part of each element.
Using links and loops, the parser can navigate through the entire bitstream.
Parser results
The result of the interpreted bitstream is a comma-separated list of values which is dis-
played in the "Message" view (see
Recording GBAS data
When you record and export the results of a GBAS measurement, all measured values
and the bitstream for each record are stored as a comma-separated list. This basic
CSV file contains a data link for each record in the list. The link points to a further CSV
file which contains all human-readable texts for that record. All data files for the current
recording are stored in a sub-directory that is exported together with the basic CSV file.
The file with the human-readable text values contains the data that is displayed in the
"Message" view.
Example:
One row of data from the basic CSV file for list number 20 (
