Description (
Characters: 3424 of 4000
)
Improve your experience at sea with OnCourse, the new boating and sailing navigation aid from MarineTraffic, the global leader in vessel tracking. OnCourse helps you stay aware of the traffic around you, plan your voyages, while sharing your position with your friends and loved ones through the MarineTraffic Live Map. Also, you can engage with the boaters’ community and have fun with the new exciting Virtual Reality feature. Increase your awareness while sailing - Plan and monitor your voyage* - Calculate the optimal route* - Add your own customisable waypoints to the map - Collision detection & avoidance while sailing, with AIS - Additional information during sailing (time to next waypoint, next ETA, final ETA, distance & bearing to waypoint) Share your position on MarineTraffic.com and engage with the boaters’ community - Report your own position even if your boat is not equipped with an AIS transponder, so that your friends and family can follow you in near real-time - Track a particular boat in a race or keep in touch with friends’ boats whilst cruising - Identify other vessels that are sailing in the area (provided that they transmit their positions) - Upload photos of your boat for all the community to see Have fun! - Recognise vessels by using the Augmented Reality tool* - Try out the new Virtual Reality feature and watch everything from a different perspective (requires a VR headset)* Very low data and battery consumption All standard units of measurement supported (*) Available only with OnCourse Plus subscriptions 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.}

The only app with virtual AIS transponder function. Its not just cool to be able to show a small boat that has no dedicated AIS transponder on AIS maps, but also add safety by making it more visible to other sailors.

die App ist sehr funktional für Sportbootfahrer. Gibt die Position aber nur auf Marinetraffic wieder.

Nutzlose App da Positionsmeldungen nicht übernommen werden. Ich habe den Fehler zurückgemeldet, Fehler wurde als bekannt bestätigt, jedoch wurde nun seit 4 Wochen nichts unternommen.

Updates to marine traffic are sporadic at best, it updated once taking 3 hrs + to update, but since then it has never updated my position on marine traffic. The principal is great but this app just doesn't work. What a poor effort. Others report the same experience. If you select help in the app it takes you to a broken link. Enough said. Don't waste your time installing unless they fix all the issues.

I was excited to discover this app, but it's not working for me. App claims it's successfully send my position but my location on the Marine Traffic site never appears.

I've enjoyed using this app for a year or so and have found it very handy for reporting my position. However, it's stopped sending my position data, which is very disappointing.

Very glitchy. Works much worse than it used to. When you start sailing, the signal only lasts for a couple minutes then turns off. Has now become useless.

De momento no lo he probado, pero si sirve para alguien el registro hay que hacerlo en Marine traffic y utilizar ese usuario y contraseña para logearse en Oncourse. (Un pequeño lio).

I don't find the app easy to understand and so far I don't see that it works. Have not seen an update on Marine traffic.
