Device Information

Device information is useful during technical support and for tracking your serial number, firmware and hardware version.

Manager Device Information

Status

The Status shows the current status of Certus as reported by sections System State Packet (ID#20) and Raw GNSS Packet. (ID#29).

Note: The following Status flags do not update for Certus units with a Trimble BD992 GNSS Receiver. These flags are only applicable to Aries GNSS Receivers: GNSS 2, Antenna 1 disconnected, Antenna 2 disconnected, Antenna 1 short, Antenna 2 short

Manager Status Dialogue

Satellites

The Satellites dialogue shows detailed information on the satellites that are visible to the Certus GNSS receiver.

The information is displayed as a satellite skyplot, a table and an SNR (Signal-to-Noise Ratio) graph. A maximum of 28 satellites will be displayed, even if more are accessible. This plot shows the SNR of each satellite at the primary and secondary antenna. As a guideline, these should be within 5-10 dB of each other in the absence of cable or antenna faults. Elevation and azimuth are in units of degrees.

Raw Sensors

Raw sensors shows the temperature calibrated raw sensor values.

Temperature readings are available for a range of sensors: T(Ax), T(Ay), and T(Az) correspond to the accelerometer's x, y, and z axes; T(Gx), T(Gy), and T(Gz) relate to the gyroscope's X, Y, and Z axes; T(M) is for the magnetometer; and T(P) indicates pressure.

Orientation

Orientation shows the Certus orientation, angular velocity and orientation error. To enhance the user's understanding of some of the less intuitive metrics, Course is defined as the path determined by measuring sequential positions, and Slip is the difference between the heading and the course.

Manager Orientation Outputs

Position

Position shows the Certus position and position error. Latitude and longitude are converted to North and East metres from a reference point that can be reset.

Manager Position Outputs

Velocity and Acceleration

Velocity and Acceleration shows the Certus velocity, acceleration and g-force.

Manager Velocity and Acceleration Outputs

Time

This dialogue box allows the to view the time for the connected device. Views are in Unix, UTC, or Local time formats to best suit user requirements to ensure accurate timekeeping and synchronisation across systems.

Time Dialogue

Communications

This dialogue shows statistics on the data packets received from Certus and can be useful in diagnosing signal integrity problems.

Manager Communications Dialogue

GNSS Receiver Information

This dialogue shows information about the GNSS receiver fitted to the Certus.

Manager GNSS Receiver Information Dialogue

Heave

For the Heave dialogue to function the heave packet (ID 58) must be set to output periodically using the Packet Rates dialogue.
