Description
The Cassens & Plath Artificial Navigation Horizon 47100 is a professional sextant artificial horizon designed for use in astronomical navigation when the natural horizon is not visible. The instrument enables precise observations of the sun, stars or planets even in conditions where traditional navigation with a visible horizon is not possible.
An artificial horizon acts as a stable reference when the navigator uses a sextant to measure elevation angles of celestial bodies. The Cassens & Plath Artificial Navigation Horizon utilizes a precise bubble level that establishes a stable reference horizon, allowing navigational observations to be made with high accuracy even when observing on land or in areas where the natural horizon is obscured.
This makes an artificial horizon an important aid in classical astronomical navigation, especially in connection with navigation training, celestial navigation courses or sextant training. The instrument is often used by maritime schools, navigation students and experienced navigators who want to practice astronomical observations without being dependent on a visible sea horizon.
Developed and manufactured by Cassens & Plath in Germany, the Artificial Navigation Horizon 47100 is BSH type-approved, which means that the instrument meets the requirements for navigation equipment for maritime use. Cassens & Plath is one of the world’s most recognized manufacturers of navigation instruments, and their sextants and navigation equipment are used by maritime educational institutions, research vessels and professional navigators around the world.
The artificial horizon is typically used in situations where observations need to be made on land, during navigation courses or in areas where weather conditions, terrain or ice make it difficult to observe a natural horizon. Together with a sextant, the instrument allows the navigator to perform complete astronomical navigation calculations based on observations of the sun or stars.
The Cassens & Plath Artificial Navigation Horizon is a precision instrument designed for long life and stable use in demanding maritime environments, and is an essential accessory for anyone working with sextant and astronomical navigation.
