SeaStateAid

Real-time display of sea state, compass and artificial horizon.

Real-time display of sea state, compass and artificial horizon on phones and tablets.

This application uses the device's internal 3-axis sensors to compute:

1) Sea State (swell height and period)

2) Compass (heading)

3) Artificial Horizon (roll and pitch)

Several display formats are available to monitor this information.

Note: The swell height and period are determined by estimating the vertical movement of the device. The estimate is affected by errors and drift associated with the accelerator sensor. The program reports the swell height and period of the device, which, depending on the size of your vessel, are not necessarily the same as the swell height and period of the waves.
