This sensor integrates an inertial measurement unit (IMU) and a dual-band, quad-constellation internal GNSS receiver, complemented by advanced sensor fusion algorithms, ensuring precise position and orientation even in the most challenging environments.\u003c\/p\u003e\n\u003ch3\u003ePositioning and orientation accuracy\u003c\/h3\u003e\u003cp\u003eThe Ellipse D Marine stands out for its accuracy. In horizontal position, it achieves 1.2 m in single point mode, and an RTK performance of 0.01 m + 1 ppm, comparable to larger systems. For applications requiring extreme precision, PPK post-processing delivers horizontal accuracy of 0.01 m + 0.5 ppm. Regarding orientation, roll and pitch are measured with an accuracy of 0.1° in single point mode, improving to 0.05° in RTK and 0.03° in PPK. Heading, thanks to its dual antenna, can reach 0.1° with PPK post-processing. Heave compensation is self-adjusting, ensuring an accuracy of 5 cm or 5% of the wave height (whichever is greater) for wave periods ranging from 0 to 20 seconds.\u003c\/p\u003e","brand":"SBG Systems","offers":[{"title":"Ellipse D \/ Standalone display unit","offer_id":53723746369876,"sku":"100-2422","price":7064.1,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/ellipse-d-ins-unit-right.png?v=1778229811","url":"https:\/\/skysat.fr\/en-ae\/products\/sbg-systems-ellipse-d-marine-inertial-navigation-system","provider":"Skysat","version":"1.0","type":"link"}
