Specifically, it operates on the 500 kHz frequency in the MF band and the 4226 kHz frequency in the HF band, along with other maritime frequencies allocated for NAVDAT use. NAVDAT supports the transmission of various types of data, including text, images, and other digital files, providing a modern digital alternative to traditional systems like NAVTEX. The NAVDAT receiver equipment should comprise a radio receiver, an appropriate antenna, a signal processor with non-volatile memory, a human-machine interface, data interfaces and an integrated display; or a connection to external equipment with a display (e.g. an integrated navigation system).
