To control the Sailbuoy access to a website is given. There you can update waypoints and download data from the Sailbuoy. Also here user friendliness has been a priority. Experience has shown that most of the time used, goes towards monitoring the progress of the Sailbuoy during the mission. The website is also adapted to mobile phone usage. Here the operator can log in to control and monitor the Sailbuoy's progress. The payload communication also uses the same interface for control and data retrieval.
