On occasion, we are asked to explain why a customers vessel might not be appearing on AIS websites as there may be some concern that the unit is not operating correctly. If you are concerned that this may be the case with an AIS transceiver then please consider the following before contacting us:
1 - Coverage. Not all AIS websites offer complete coverage, so there is a chance that you may be out of range of a receiving station for that site. In addition, the site may not be offering real-time information.
2 - Antenna setup. If a vessel is being seen by other vessels around it, but not by an AIS website, then the issue could be associated with the choice/installation of VHF antenna. If in doubt, refer to the user manual for advice or contact us for help.
3 - Unit configuration. Make sure that the AIS transceiver you are looking for is correctly setup with its complete vessel details and that it is connected to a GPS antenna (as per the user instructions)
