“…As to interference sources, now there are two methods to achieve anti-interference. One of them is to cut off the interference source to achieve the purpose of antiinterference [6], while the second method is to adjust the technology of emission control and improve the overall safety of the control system. As for the receiver, the purpose of anti-interference is usually achieved by improving the function of the receiver [7].…”

“…"It is expected that the GNSS receiver will be the primary source of position information for the autonomous ship" (Felski & Zwolak, 2020). "Being such widely used and essential tool GPS is becoming an attractive target for criminals and hackers" (Ahmad et al, 2019). Therefore, this system will be fully responsible for keeping the vessel in position, so resilience to threats for this system is essential.…”

The increasing expansion of Operational Technology (OT) and the digitalization of Information Technology (IT) in maritime transportation, as well as the equipping of ships with more automation, despite many benefits, introduces numerous cyber risks, especially with unauthorized access to data and ship systems. Due to the above, it becomes important to raise awareness and take measures to ensure adequate security; this is also important at the level of the virtual securing of ships. This article consists of an introduction to the topic. It presents the current trends and directions of development of maritime transportation and the risks related to them. It contains an overview of the current safety systems on ships and the present safety resolutions. Then, it describes issues related to modern piracy and the weaknesses of ship systems most vulnerable to cyber-attacks.

“…Celestial navigation is an important way to realize automated navigation by detecting the celestial bodies with known accurate spatial positions [5]. It does not rely on any external man-made facilities, and therefore is not susceptible to spoofing attacks and signal blockage and jamming [6]- [8]. In addition, since the positions of celestial bodies are absolute at a given moment, celestial navigation has no cumulative error so that it is of high value in long-timeduration missions [1], [9].…”

For celestial measurement, it is difficult to enable a single optical system to image and measure both stars and the sun due to vastly different light intensity of targets and limited response capability of the image sensor pixel. Here, we develop an all-day optical attitude sensor integrating stars and the sun measurement based on extended pixel response model of the CMOS APS (Active-pixel sensor) imager. For extremely large light intensity, we extend the conventional pixel response model to the oversaturated stage where the pixel values reverse and drop below the saturation value. Based on this, the integration of the star sensor and the sun sensor is realized. The pixels image the starry sky with linear response, and make use of the oversaturation response to image the sun and obtain a black spot on the bright background. This principle enables the capability of all-day high-precision attitude measurement using a single miniaturized sensor. An integrated optical attitude sensor is designed and manufactured. Ground-based observation results show that the orientation accuracy from sun measurement is better than 9" (3σ), and the attitude accuracy from star measurement is better than 5" (3σ) for pointing and 11" (3σ) for rolling. The sensor can be applied to high-precision all-day navigation systems for miniaturized spacecrafts and aircrafts.
