Wave Static Mode is designed for specific conditions where the surface position is relatively predictable, and the user wishes to define a measurement window around this known surface, including the velocity cell positions. This mode can be beneficial if the surface position does not vary significantly and if you wish to constrain the detection range within set boundaries to reduce the likelihood of inaccurate measurements.

However, in practice, this mode is rarely recommended or utilized. The reasons include:

• Tidal elevation changes, which make it difficult to set precise measurement positions.
• Variable sea states, leading to unpredictable surface positions.
• Deployment depths that often differ from initial planning or intended locations.

In most cases, the standard mode, where the measurement volumes and Acoustic Surface Tracking (AST) window are automatically configured, is more effective. This mode works well because the AWAC profiles for 60 seconds just prior to each wave burst, providing a reliable estimate of the mean sea level and approximate sea state.

For the majority of deployments, we recommend using the standard mode and avoiding Wave Static Mode unless there are specific circumstances that require it.

Please note that this information applies to AWAC models released prior to 2024. For newer models, refer to the updated system documentation for further details.
