Format Description of GBAS and SCAT-I
Data
The Data Recorder records and manages the data captured during one or a series of
measurements. Up to 999 lists with a maximum of 1 000 000 data lines each can be
recorded. One line corresponds to the captured data at the receive frequency for the
GBAS/SCAT-I signal in one time slot.
Similarly, a data stream consists of lines of measurement results, where one line corre-
sponds to the captured data at the receive frequency for the GBAS/SCAT-I signal in
one time slot.
You can also query a single measurement result, which corresponds to one row in the
Data Recorder list.
In all three cases, the available parameters and their format are identical.
Which parameters are recorded is user-definable and can be defined individually for
each list. The following overview describes all available parameters (full list) in their
default order.
The format of the data for each slot is identical, regardless whether a parameter con-
tains data or not. Thus, you can create a table from the exported comma-separated
list. If a slot is empty, only the general data is stored in the list entry; the message-spe-
cific parameters are cropped.
When a list is stored to a file, a header line is automatically included that describes the
provided parameters.
General Information
The following general information is always included, regardless whether the slot con-
tains data or not, and whether the signal is GBAS or SCAT type.
