Functional service at your service!
STM is built on message format that can be combined into different services. The sevices might be used as they are or elaborated into something new depending on what the service provider offers.https://stm-stmvalidation.s3.eu-west-1.amazonaws.com/uploads/20190212142308/User-guide-STM-validation1.4.pdf
Which service is where and for whom?
A service can be restricted in terms of area or time. The services available in the testbed on your ECDIS onboard will be added here below as they go live.
