The first line of this output is described in the following table:
Data Field Description
$JLBEAM Message header.
Sent frequency This field provides the frequency sent to the digital signal processor.
Used frequency This field provides the frequency currently being used by the digital signal processor.
Baud xxxx This data field provides the currently used baud rate of the acquired signal.
Geo xxx This field provides the currently used satellite’s longitude, in degrees.
The second line, and those that follow, are described in the following table:
Data Field Description
$>JLBEAM Message Header.
frequency This data field provides the frequency of the spot beam
longitude This data field indicates the longitude of the center of the spot beam, in degrees.
latitude This data field indicates the latitude of the center of the spot beam, in degrees.
baud This field indicates the baud rate at which this spot beam is modulated.
satlongitude This data field provides the satellite’s longitude, in degrees.
An example of this response follows:
$>JLBEAM,Sent 1551.4890,Used 1551.4890,Baud 1200,Geo -101
$>JLBEAM,1556.8250,-88,45,1200,(-101)
