Description of log files content
Below are the specifications of the contents stored inside the ADR file, that is a .txt file but can easily
be opened in other formats for the necessary calculations.
The file consists of a string for every second, containing different values, comma separated , in
which are the recorded data supplied by the onboard instrumentation connected to GAMP.
Below Is an example of the structure of the strings:
$ESA,Ts,ax,ay,az,Time,Date,AWA,AWS,AWS1,TWA,TWS,TWS1,BS,HDGt,HDGm,Lat,Lon,Lon1,Fix
,Depth,MagDev,MagDev1,MagVar,MagVar1,Temp,SOG,TrackT,TrackM,checksum
Below is the code of the recorded data and the relative position within the string. It starts with $ESA,
note that not necessarily within the various fields appearing all data, for example if the GAMP is not
connected with some instrument measuring the accellerations, the corrispondent fields will be empty
(comma separated)
