Note: OnCourse is not AIS, OnCourse simulates the data transmitted by AIS transponders; however, it only transmits data through the Internet and not over AIS radio-frequencies. The information transmitted by OnCourse is not visible by the AIS receivers of other vessels. It will only be displayed on the MarineTraffic website and apps. As such, OnCourse is a self-reporting tool that does not substitute AIS transmissions and it is not, by any means, related to the safety and navigation equipment of a vessel.

Intended use
Provided that Internet connectivity is available, the vessel's positions will start being reported once the OnCourse application is launched on your mobile device. Note that the positions will continue being reported even if the app is running in the background! It is important to be used only when the device is on board a vessel and it must be turned off whenever the device leaves the vessel!

How to use OnCourse - Registration Required
Registration for a MarineTraffic account is required in order to start reporting your position through the application. The details of the vessel (such as vessel's name, call-sign, dimensions, destination, ETA, etc) must be also configured when using the app.

Email notifications
In order to avoid unwanted position reporting, MarineTraffic will send e-mail notifications at your registered email address, whenever your app is active. This serves as a reminder that position reporting should only be active when you are at sea and must be turned off when on land.

Disclaimer
This application is to be used for informational reasons and as navigation assistance. This is not a substitute for the good seamanship practices, the onboard navigation and safety instruments required by applicable regulations.

Continued use of GPS running in the background can decrease battery life.
