This video shows how to create parallel index lines and set it to radar. It shows how to determine the PI lines including the Not More Than (NLT) and Not Less Than (NMT) PI lines when making a passage plan. Parallel indexing is a navigation technique used by mariners to maintain a safe distance from a navigational hazard or to ensure that the vessel stays on a desired track. This method involves using radar and electronic navigational charts, or paper charts to create reference lines, known as index lines," parallel to the ship's course, to continuously monitor a vessel’s track, to a pre-determined passage plan.#PI #Radar #Navigation #Ecdis

This video is intended for maritime students taking a navigation course about ship's position-fixing technique by radar range and bearing. It shows how to determine range and bearing on the radar and plot manually on the paper chart.#Radar #Navigation #FixPosition

This video is intended for maritime students taking a navigation course about ship's position-fixing technique by Crossbearing. It shows how to determine ship's position using 2 or 3 navigational aids.#Radar #FixPosition #Technique #Navigation

This video covers Radar motion displays. It shows the difference between True & Relation Motion with the ship's trails and vectors.
In True Motion, own ship moves across the radar screen in its true direction of movement, and targets move according to their actual paths. It displays the actual movement of both own ship and all targets relative to a fixed reference, usually the ground or earth. All stationary targets, such as landmasses, buoys, or anchored vessels remain fixed in position on the radar screen.
In Relative Motion display, all other targets appear to move relative to our ship. Even stationary targets, such as buoys, landmasses, or anchored vessels, appear to move relative to own ship's position.#Radar #RM #TM #Training

This video is intended for maritime students and those taking a Radar Plotting Course. Part 1 of 2 covers how to determine CPA, TCPA, RCPA, BCPA, BCR, BCT, DRM, and Target Relative Speed, along with a brief explanation of the 6-minute rule.#Radar #Plotting #Training

This video is designed for maritime students and those taking a Radar Plotting Course. Part 2 of 2 focuses on Collision Avoidance, covering how to determine own ship’s new course and speed. It also includes Mx, NRML, ARML, NDRM, along with a brief explanation of the 6-minute rule.#Radar #Plotting #Training

This video shows the difference between the Closest Point of Approach (CPA) and the Bow Crossing Range (BCR). These terms are essential for collision avoidance and safe navigation.
CPA represents the closest point at which two vessels will approach each other if both maintain their present courses and speeds. It is a point along the target’s relative motion line at which the shortest distance will occur between own ship and the target if both continue on their present courses and speeds.
BCR is the distance at which a target vessel will cross ahead of own ship’s bow or astern if both maintain their present courses and speeds.#Radar #CPA #BCR

⚓️ Балтика: официально предупреждают о помехах GNSS, AIS, RADAR и DGPS

🛰 Шведская морская администрация Sjöfartsverket распространила навигационное предупреждение BALTIC SEA NAV WARN 030/26 от 12 октября 2026 года (09:12 UTC).

📡 Помехи отмечены сразу в четырёх системах:
• GNSS — спутниковое определение координат;
• AIS — идентификация и отображение судов;
• RADAR — радиолокационное наблюдение;
• DGPS — дифференциальные поправки GPS.

🌍 География: южная, юго-восточная, центральная и северная Балтика, Финский и Рижский заливы, Аландское море.

⚠️ Чем это опасно? В дополнительных разъяснениях Sjöfartsverket описаны реальные последствия навигационных помех:
🔴 Неверные координаты судна на ECDIS. Даже небольшая ошибка опасна в узкостях.
🔴 Ложные данные AIS могут создавать видимость опасного сближения или искажать оценку движения других судов.
🔴 Помехи могут возникать внезапно и продолжаться от коротких эпизодов до длительных периодов.

🛡 Рекомендации судоводителям:
• Иметь два независимых способа определения места;
• Проверять координаты по береговым ориентирам;
• Использовать RADAR для контроля дистанций, если его показания достоверны;
• Проверить зависимость судовых систем от GNSS;
• Отслеживать NAVTEX и предупреждения для мореплавателей.

⚠️ Важно: механизм помех не установлен. Нельзя утверждать, что все случаи вызваны jamming или spoofing. Число затронутых судов не опубликовано.
