Abstract
In order to improve navigation and communication technology, multi-source data mixing technology was applied. First, the background and domestic and foreign research status were summarized. The communication technology, positioning technology in navigation, and radio orientation technology were introduced. Then, based on the multi-source data of the ship communication, the embedded hybrid platform was built. According to the configuration of the hardware, the kernel source code was modified and ported to an embedded hybrid platform. Finally, according to the FHS standard, a root file system was established. The multi-source data hybrid communication system display interface and multi-source data fusion PRONAVI system were designed. The results showed that the platform could manage and store all types of collected data. Therefore, this technology can mix and transmit multi-source data.
Highlights
With the advent of the information age and the development of maritime communications and terrestrial navigation, civil and military communications and navigation require data transmission to ensure real-time, reliability, high-speed, and confidentiality
After receiving the signal sent by the directional module, the identification number ID can be determined through demodulation, the direction of the transmission source is determined by the directional antenna, and the search is completed
The communication facilities and information types between ship and ship shore are not uniform. This brings about various problems such as cumbersome operation, low terminal intelligence, and high communication costs
Summary
With the advent of the information age and the development of maritime communications and terrestrial navigation, civil and military communications and navigation require data transmission to ensure real-time, reliability, high-speed, and confidentiality. Under the communications environment of oceanic fisheries communications dispatch, military communications, and transportation of dangerous goods, multiple sources of data such as voice, pictures, and documents need to be transmitted at the same time. The advantages of shortwave's low cost and the special use of medium and long-distance communication bands in maritime communications and military communications should be utilized. In order to meet this requirement, embedded software and hardware platform and data hybrid communication and navigation technology are applied. The realized mixed data communication and navigation technology has high application value for maritime, military or special-purpose fields. It provides the necessary methods and technical guarantees for the development of maritime powers
