One message is displayed in 4 columns indicating the ZULU time at which data is received, the
source of the message (receiver on which data is received, connection type for NMEA), the type of
data and the content of the message.
Below are the types of messages that are displayed:
1 Heartbeat: Receiver inputs. Read to check if computer is correctly connected to the receiver.
2 Sensor Data: Inputs from PRP sensors. At each ping of the sensor, shows one message for
raw data and one message for filtered data. One message contains the type of data sent by
the sensor, the node number, the hydrophone receiving data (such as H1, H2) and the quality
of the reception. Read these messages to check if data is correctly received. Look at the
names of the receiving hydrophones to know on which hydrophone data are better received.
3 Sonar Data: Inputs from narrow band sensors (digital communication). At each ping of the
sensor, shows one message for raw data and one message for filtered data. One message
contains the type data sent by the sensor, the node number, the direction of the ping and the
hydrophone receiving data. Read theses messages to check if data is correctly received. Look
at the names of the receiving hydrophones to know on which hydrophone data are better
received.
4 Console: Used for development only. Not displayed by default.
5 NMEA: Displays full NMEA sentences that are received. Read these messages to check if
NMEA sentences from external devices (such as a GPS) are correctly decoded.
6 Filter: Filter messages. For example, type Temp to only display temperature data.
7 Devices: Receivers on the system.
