Robust Response of BA-FLS-NX5 to Severe Cold

Blue Aspirations deployed the BA-FLS-NX5 floating LiDAR System in the north of China. It has gone through the entire harsh winter with extreme experiences of rain, snow, and freeze, especially from December 2023 to February 2024. During the inspection, it was found that although the system was covered with thick ice and snow, all components were in good condition.

According to the site temperature recorded by the system from December 1, 2023, to February 29, 2024:

The minimum temperature in the sea area of the project site reaches -14 ℃, the maximum temperature is 12 ℃, and the daily average temperature is about 0 ℃.

The sea area of the project site is cold in winter and lacks sunlight. BA-FLS-NX5 is not only designed with solar panels and wind turbines for power supply but also with a remotely controllable large-capacity fuel cell to ensure the voltage stability of the system under extreme cold conditions.

Figure 3 shows that from December 2023 to February 2024, the system was mostly covered with ice and snow, which seriously affected the power supply of solar panels and decreased voltage. Thanks to the system's redundant power supply design, the fuel cell took effect under this condition to ensure the system voltage remained stable above the safety voltage of 23.5V.

During this campaign, the system availability was 100%, and the data availability exceeded 97.8%, with the mean value reaching 98.9%. It far exceeds the requirements of relevant standards.

Under extreme conditions such as severe cold, ice, rain, and snow in the northern cold sea, the floating LiDAR system BA-FLS-NX5 has again fully demonstrated its high reliability and survival ability.
