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.
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]
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.
Aura (EOS CH-1) is a multi-national NASA scientific research satellite in orbit around the Earth, studying the Earth's ozone layer, air quality and climate. [2] It is the third major component of the Earth Observing System (EOS) following on Terra (launched 1999) and Aqua (launched 2002).
The Sun follows this type of orbit about the Galactic Center of the Milky Way. Heliocentric orbit: An orbit around the Sun. In the Solar System, all planets, comets, and asteroids are in such orbits, as are many artificial satellites and pieces of space debris. Moons by contrast are not in a heliocentric orbit but rather orbit their parent object.
The value of a solar beta angle for a satellite in Earth orbit can be found using the equation = [ + ()] where is the ecliptic true solar longitude, is the right ascension of ascending node (RAAN), is the orbit's inclination, and is the obliquity of the ecliptic (approximately 23.45 degrees for Earth at present).
Five small satellites, including one from the Taiwan Space Agency, were on board the rocket, which was headed into sun-synchronous orbit roughly 500 km (311 miles) above the Earth's surface.
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]
