From the View menu, you can select pages to view real-time data from the INS.
Map
[INS Manager - Desktop only]
View > Map takes the user back to the home which features the map display.
Device Information
The Device Information page is useful when requesting technical support. It displays the unit's:
- Serial number.
- Device ID.
- Firmware version.
- Hardware version.
Status
The Status dialogue shows the current system status, filter status, and GNSS status flags, as reported by System State Packet (ID#20) and Raw GNSS Packet. (ID#29)
INS Manager Desktop Status Dialogue
Satellites
The Satellites page shows detailed information on the satellites visible to the INS GNSS receiver. The display includes a satellite skyplot, a table, and an SNR (Signal-to-Noise Ratio) graph.
The plot shows the SNR of each satellite or each satellite at the primary and secondary antenna. As a guideline, SNRs should be within 5-10 dB of each other in the absence of cable or antenna faults. Elevation and azimuth are displayed in units of degrees.
INS Manager Web Satellites Table
Raw Sensors
The Raw Sensors page displays the raw IMU sensor values.
The plots include accelerometer, gyroscope, and magnetometer readings. Temperature readings are provided for a range of sensors, including T(Ax), T(Ay), T(Az) for the accelerometer axes; T(Gx), T(Gy), T(Gz) for the gyroscope axes; T(M) for the magnetometer; and T(P) for the pressure sensor.
The lower plot visualizes air pressure. Internal temperature sensors are also reported but do not reflect the general environmental temperature.

Orientation
The Orientation page shows the INS orientation, angular velocity, and orientation error.
Courseis the path determined by measuring sequential positions.
INS Manager Desktop Orientation Outputs
Position
The Position page shows the INS position and position error (standard deviation). Latitude and longitude are converted to North and East metres from a reference point.
The position reference point can be reset in INS Manager - Desktop or by refreshing the web page in your browser with INS Manager - Web.
INS Manager Desktop Position Outputs
Velocity and Acceleration
The Velocity and Acceleration page shows the INS velocity, acceleration, and g-force over time.

Time
[INS Manager - Desktop only]
The Time page displays the time for the connected device in Unix, UTC, or Local time formats, ensuring accurate timekeeping and synchronisation across systems.
INS Manager Desktop Time Dialogue
Communications
[INS Manager - Desktop only]
The Communications page shows statistics on the data packets received from the INS (e.g., packets decoded, bytes discarded, LRC/CRC errors and is useful for diagnosing any signal quality problems on the connection, such as signal strength or connectivity.

Subcomponent and GNSS Receiver Information
The INS Manager Web > View > Subcomponent Information and INS Manager Desktop > View > GNSSS Receiver Information displays detailed information about the GNSS receiver fitted to the INS.
INS Manager Desktop GNSS Receiver Information Dialogue
If your device is fitted with a Trimble GNSS receiver, the Desktop dialogue features a License Update text field. To upgrade your licence, copy and paste the license key into the License Update field and click Send.
Vessel Motion
This page displays the vessel motion (heave, surge, sway) at up to 4 reference points. For data to display, the Vessel Motion Packet (ID 89) must be configured in the Configuration Menu dialogue. Reference point offsets are configured in the Configuration Menu dialogue.
INS Manager Web UI Vessel Motion Page
Heave
This page displays the heave at up to 4 reference points. For data to display, the Heave Packet (ID 58) is configured in the Configuration Menu dialogue. Reference point offsets are configured in the Configuration Menu dialogue.

North Seeking Status
Coarse Alignment is used to derive the heading based on a gyrocompass’ estimation of True North. Coarse alignment is necessary to establish an approximate heading when an alternative heading source (e.g., dual antenna or velocity) is unavailable. Once coarse alignment is complete, the gyrocompass is used for fine alignment.
The Coarse Heading Alignment Status page displays the current status and initialization messages:
| Status Messages | Description |
|---|---|
| Awaiting position via GNSS or manual initialisation | An approximate position is required. Initialisation commences once position is available (via GNSS or the Manual Initialisation page). |
| Initialising, please wait | The process of determining the coarse heading has started. This takes approximately 2 minutes, unless motion is excessive or latitude changes significantly. |
| Alignment initialised via alternate source | Coarse alignment is bypassed because heading has been successfully established via an alternate source (e.g., dual antenna, velocity, or external input). |
| Heading coarse alignment complete | The system has successfully determined an approximate heading. |
Coarse Heading Alignment - Status Messages
| Warning Messages | Description |
|---|---|
| Initialisation restarted - excessive motion detected | The initialization has restarted due to excessive motion (linear acceleration limit of 2 g and angular rate limit of 50 deg/s). |
|
Initialisation restarted - change in latitude detected |
The initialization has restarted due to a significant change in latitude. |
| Initialisation restarted - Change in COG lever arm detected | The initialization has restarted due to a change in the Centre of Gravity (COG) lever arm configuration. |
| Warning - Check latitude, value out of range | A discrepancy between the current latitude and the coarse alignment algorithm was detected. Verify the current latitude is correct. |

External Data Selection
[INS Manager - Web only]
This page acts as a jump page to open time-based data graphs for each supported external source. External sources must be connected and configured appropriately for the corresponding packet to report valid data.
