Simons

Ship Monitoring Suite

  • Print
General Information

Ship Monitoring System

Simons is a ship monitoring system used to detect and track ships using a combination of Earth observation imaging and cooperative streaming technologies. The suite is conceived as a background processing module that can be integrated in value-added systems at a higher level. This modular vision extends to the internal architecture of Simons, with interconnected, high-efficiency independent submodules. Simons can work with any type of Earth observation imaging and cooperative streaming system, and supports all standard data formats. Output is provided via layers of information published with web services or an advanced GMV viewer called Socrates.

5 to 10 min

Processing time based on image size.

> 95%

Probability of detection.

~ 70%

Probability of categorization (length at least 12 times the image resolution).

Milestones

Simons

Simons has been tested successfully in a wide range of operational campaigns under very diverse observation conditions and scopes of interest.

Características Simons 2

Localization of a small broken down vessel with migrants in quickly deteriorating health.

Características Simons 3

Localization of a ship suspected of conducting illegal fishing activities.

Características Simons 4

Localization of a group of ships traveling together to conduct illegal fishing activities.

Vertidos en el mar
