The marine Automatic Identification System (AIS) is a location and vessel information reporting system. It allows vessels equipped with AIS to automatically and dynamically share and regularly update their position, speed, course and other information such as vessel identity with similarly equipped vessels. Position is derived from the Global Positioning System (GPS) and communication between vessels is by Very High Frequency (VHF) digital transmissions. There are a number of types of AIS device, like Class A transceivers, Class B transceivers, AIS base stations, Aids to Navigation (AtoN) and AIS receivers.
QK-A024 is a compact dual channel, VHF AIS receiver and is able to receive information from both AIS frequencies simultaneously. It can also combine one external NMEA0813(4.8kbps) data source with GPS and AIS messages. This single data stream is then transmitted synchronously via WiFi, USB and RS422.
QK-A026 includes all of the features of the QK-A024 and includes an integrated GPS module. Both of them share the same capabilities for most other features; therefore they are covered together in this document.
