GENERAL WARNINGS
All marine Automatic Identification System (AIS) units utilise a satellite based system such as the Global Positioning Satellite
(GPS) network or the Global Navigation Satellite System (GLONASS) network to determine position. The accuracy of these
networks is variable and is affected by factors such as the antenna positioning, how many satellites are used to determine a
position and how long satellite information has been received for. It is desirable wherever possible therefore to verify both your
vessels AIS derived position data and other vessels AIS derived position data with visual or radar based observations.
The proAIS application is intended for use as an installation and configuration tool. The application is not a navigation tool
and should not be used as such.
LICENSING
IMPORTANT: In most countries the operation of an AIS unit is included under the vessels marine VHF licence provisions. The
vessel on to which the AIS unit is to installed must therefore possess a current VHF radiotelephone licence which lists the AIS
system and the vessel Call Sign and MMSI number. Please contact the relevant authority in your country for more information.
In accordance with a policy of continual development and product improvement the SRT-MTB hardware and software may be
upgraded from time to time and future versions of the SRT-MTB may therefore not correspond exactly with this manual. When
necessary upgrades to the product will be accompanied by updates or addenda to this manual. Please take time to read this
manual carefully and to understand its contents fully so that you can install and operate your AIS system correctly.
