Sonardyne Lodestar Firmware 3.07.00 Release Notes
3.07.00.2139
Summary
This firmware release is based on the v3.04.00.1080 release and supports the following hardware/Systems:
- Lodestar / SPRINT
- Lodestar-Nav / SPRINT-Nav
- Gyro USBL (Optimised USBL)
This firmware is NOT supported on the following Hardware/Systems:
- DP INS
- Gyro Compatt 6(+)
The focus of this release is to support the following improvements in the LNav/LNavUTC output messages, Ethernet and to support latent USBL Observations.
34338 – LNav & LNavUTC output message improvements
LNav/LNavUTC supports two modes of operation; Sensor Mode that populates the message with AHRS and sensor data, and Hybrid Mode that populates the message with aided INS solution. This includes new commands that control the quality level for transition between the two modes. See appendix for details.
34290 – Latent USBL Observations:
SPRINT now supports USBL position latency of 29 seconds. This is particularly useful when position aiding an AUV via a slow acoustic communication link. See user manual for details.

Installation Notes:
To update to 3.07.00.2139 firmware, connect using CP+E1 Serial port connected to Lodestar PC Utility software, Reset the unit to the default configuration (Reset to factory configuration), then update firmware. Please see user manual for detailed instructions.
Note: To upgrade hardware operating firmware versions 3.03.01 or below, an additional configuration file is required specific to the unit for successful update, please contact support for instructions.
Appendix A – LNav/ LNavUTC Output message
The LNav / LNavUTC messages in the v3.07 firmware support two output modes
(Sensor and Hybrid) that populate message fields as shown in the data format
table below.
Sensor Mode: Data populated from AHRS and raw sensors.
Hybrid Mode: Data populated by aided INS solution

Note:
Transition from sensor mode to hybrid mode is dependant on the depth standard deviation and the velocity standard deviation, default below:
- Depth standard deviation default threshold set to 0.25
- Velocity standard deviation threshold set to 0.15
These thresholds can be custom configured using the following command: OP INSTHRESH E.g. OP INSTHRESH 0.25 0.15 For full description of the LNav / LNavUTC message, please refer to the latest user manual.
