A non-Sun-synchronous orbit (magenta) is also shown for reference. Dates are shown in white: day/month. A Sun-synchronous orbit (SSO), also called a heliosynchronous orbit, [1] is a nearly polar orbit around a planet, in which the satellite passes over any given point of the planet's surface at the same local mean solar time.
Each Sentinel-3 satellite is designed to operate for seven years in a sun-synchronous low-Earth orbit. The satellites use multiple sensors to measure topography, temperature, marine ecosystems, water quality, pollution, and other features for ocean forecasting and environmental monitoring.
The SMAP observatory includes a dedicated spacecraft and instrument suite in a near-polar, Sun-synchronous orbit. The SMAP measurement system consists of a radiometer (passive) instrument and a synthetic-aperture radar (active) instrument operating with multiple polarizations in the L-band range. The combined active and passive measurement ...
The orbit will be a sun-synchronous, dawn-to-dusk type. The planned mission life is three years. [ 1 ] The satellite was fully integrated in January 2024 and was performing its final testing and analysis in preparation for launch. [ 17 ]
Terra (EOS AM-1) is a multi-national scientific research satellite operated by NASA in a Sun-synchronous orbit around the Earth.It takes simultaneous measurements of Earth's atmosphere, land, and water to understand how Earth is changing and to identify the consequences for life on Earth. [1]
DMSP satellites operated in a Sun-synchronous orbit; passing over the north and south poles, the satellite would see different strips of the Earth at the same local time each day. The DMSP satellites had periods of roughly 101.0 minutes, so they would orbit the Earth 14.3
Low Earth orbit satellites take advantage of the fact that certain polar orbits set near the terminator do not suffer from eclipse, therefore their solar cells are continuously lit by sunlight. Such orbits are called dawn-dusk orbits, a type of Sun-synchronous orbit. This prolongs the operational life of a LEO satellite, as onboard battery life ...
The four satellites of the Fengyun 1 (or FY-1) class were China's first meteorological satellites placed in polar, Sun-synchronous orbit. [6] In this orbit, FY-1 satellites orbited the Earth at both a low altitude (approximate 900 km above the Earth's surface), and at a high inclination between 98.8° and 99.2° traversing the North Pole every 14 minutes, giving FY-1-class satellites global ...
