2.3 Additional Information 2.3.1 GNSS The TRENZ SIRIUS Portable Pilot Unit features an integrated GNSS receiver with a built-in antenna, enabling independent position determination. The receiver supports the following L1 GNSS standards: GPS + QZSS/SBAS, GLONASS, Galileo, and Beidou. Operational Considerations While the device offers GNSS functionality, certain conditions must be met for accurate position acquisition:
· Sky Visibility: Ensure an unobstructed view of the sky. Weather conditions can also affect signal reception.
· Interference: Avoid coated windows and proximity to excessive metal above the device, which can interfere with signal accuracy.
Please note that due to the common challenges posed by these conditions on a ship's bridge, this GNSS feature should primarily be reserved for emergency use. Its accuracy is highly dependent on external factors and cannot be consistently guaranteed.
2.3.2 ROT Calibration Understanding the calibration of the TRENZ SIRIUS Portable Pilot Unit is crucial to ensure reliable and optimal performance. Two critical calibration steps are carried out for each pilot unit before shipping:
· Temperature calibration: Each device undergoes testing to measure how its output responds to temperature variations. Using this data, a characteristic mathematical model that describes how temperature affects the gyroscope's output is calculated. This model helps establishing a correction factor to minimize errors caused by temperature, ensuring precise gyroscope readings.
· Zero-rate calibration: MEMS gyroscopes can experience drift in their bias values over time due to aging of internal components, mechanical stresses and so on. To mitigate effects of drift, a zero-rate calibration is performed every time the TRENZ SIRIUS Portable Pilot Unit is started to compensate for an offset (bias) in the gyroscope's output when it should be stationary. The user can also perform this calibration manually.
12

Autonomous Calibration at Startup During startup, the TRENZ SIRIUS Portable Pilot Unit initiates an autonomous calibration procedure. The gyroscope readings are sampled continuously for approximately 20 seconds. The average of these readings is then compared with the calibrated bias value stored in the device's memory.
· If the newly calculated average deviates from the stored bias value by more than 5 degrees per minute, it indicates that the device experienced movement during the startup phase, and the calculated average is discarded.
· If the deviation is within the tolerance of 5 degrees per minute, the stored bias value is updated with the newly calculated average, ensuring optimal calibration for subsequent operations.
Manual Bias Calibration The bias calibration process can also be initiated manually by pressing the `CALIBRATE' button. This process differs from the autonomous calibration at startup, as it does not compare the current bias value with the stored one. Instead, the stored bias value is always overwritten with the newly calculated average during manual calibration. Optimal Conditions for Manual Calibration:
· Level Surface: Perform calibration on a level surface for best results. · Minimize Vibrations: Ensure minimal vibrations during calibration. Avoid calibrating on
board a ship due to environmental motion affecting precision. · Stationary Vessel: Calibration on board is feasible if the vessel is stationary, but it may
yield less precise results compared to calibration on land. When to Perform a Manual Calibration Recalibrating the bias before each trip is generally not necessary, but it should be performed periodically. This is especially necessary if the unit exhibits a constant drift, even when stationary. Additionally, if the unit is to be operated in stand-alone mode (i.e., not connected to the ship's pilot plug), it is recommended to calibrate the device beforehand.
13

2.3.3 Continuous ROT Correction via Vessel Heading When the TRENZ SIRIUS Portable Pilot Unit is connected to a ship via the pilot plug and receives heading information from the vessel, it periodically adjusts its calculated rotational speed in recurring cycles. The correction cycle intervals are timed as follows:
· The first correction occurs after one minute. · The second correction occurs after two minutes. · The third correction occurs after three minutes. · Subsequent corrections occur every four minutes from the fourth cycle onwards. Conditions for Completing a Correction Cycle · The rotational speed (ROT) determined by the gyroscope in the pilot unit must not exceed
an absolute value of 30°per minute. · The average correction value determined in a cycle must not exceed 25°per minute. Correction Process The TRENZ SIRIUS Portable Pilot Unit compares the ROT measured by the gyroscope with the change in the ship's heading over time. If a deviation is detected, half of the difference is integrated into the ROT output by the pilot unit.

4.1 FAQ & Troubleshooting 4.1.1 Device Related The device does not start. If the device does not start, this may be due to an empty battery. Please charge the device (see `Charging'). If charging does not work, please first try an alternative power supply and/or cable to be able to rule them out as a source of error.
4.1.2 GNSS Related The SIRIUS Pilot Unit does not receive any GNSS satellite position data If the unit does not receive any GNSS positioning data please make sure that the GNSS feature has been activated (see `PPU Configuration'). Also please refer to the `GNSS' paragraph in the user guide chapter for more information about the reception of GNSS signals.
4.1.3 ROT Related ROT keeps drifting with a constant value. To compensate for a constant drift, please start the manual ROT calibration routine of the device. To do this, press and hold the `CALIBRATE' button for at least 3 seconds. The calibration process is indicated by four yellow LEDs and will take about 20 seconds. The device should lie on a flat surface and must not be moved (see `ROT Calibration').
4.1.4 AIS Related No AIS data is received and the yellow AIS LED is not blinking. If no AIS data can be received, please make sure that the connection between the vessel and the TRENZ SIRIUS Portable Pilot Unit has been established correctly. To do this, please follow the steps described under `Connecting to a Vessel'. When the connection with the vessel is successfully established, the yellow AIS LED will flash on incoming AIS sentences. If this is not the case, check (if available) if an alternative AIS cable can solve the issue.
No AIS data is received but the yellow AIS LED is blinking. If the yellow AIS LED is flashing but you are not receiving any data, this can have two causes. First, you should make sure that you have connected to the device correctly (WiFi, USB, etc.). Second, the navigation/charting software may need to be configured. Please refer to `Connecting to the Pilot Unit'.
The AIS cable seems to be not working. If you have previously purchased a TRENZ product, make sure that you use the AIS cable supplied with the Sirius PPU (see figure 1c), as the cables of the previous models are not compatible with the new generation of the TRENZ SIRIUS Portable Pilot Unit devices.

4.1.5 PPU Manager Related The TRENZ PPU Manager does not connect to the pilot unit on iOS. If the TRENZ PPU Manager does not connect to the pilot unit on Apple's iOS, please check whether the authorizations for accessing the local network have been assigned correctly. To do this, search for "Trenz Manager" in the iPhone settings and check if the access to the local network is active. The firmware update has failed. In case a firmware update failed and/or the device is without function after an update, the update process can be restarted as often as required. To do this, the device must be switched to bootloader mode by holding down the `CALIBRATE' button during power-up. In this mode, the TRENZ PPU Manager will be able to find the device and upload firmware again. If the update is done via WiFi (not recommended), it may be necessary to manually connect to the unit's wireless network beforehand.
4.1.6 Error Codes If an error condition occurs during the SIRIUS Pilot Unit startup, it will be indicated by a specific combination of red LEDs. The meaning of each error code is as follows:
Battery Error This error code indicates that there is a problem with the battery and/or the charging electronics.
GNSS Error This error code indicates that there is a problem communicating with the GNSS module.
IMU Error This error code indicates that there is a problem communicating with either one or both of the inertial measurement units.
WiFi Error This error code indicates that there is a problem communicating with the WiFi module.
