Spacecraft beta angle
WebBeta angle is defined as the angle between the orbital plane of the spacecraft and the vector to the sun (i.e., which direction the Sun is shining from). [2] The beta angle is the smaller … WebThe angles Ω, i, ω are the Euler angles (corresponding to α, β, γ in the notation used in that article) characterizing the orientation of the coordinate system x̂, ŷ, ẑ from the inertial coordinate frame Î, Ĵ, K̂ where: Î, Ĵ is in the equatorial plane of the central body. Î is in the direction of the vernal equinox.

Webβ ξ s r (b) Angles describing the influence of the solar zenith angle ξ. The solar noon angle θ describes the angle between the vector pointing to the spacecraft r and the solar noon, i.e. the vector pointing to the sun projected on the orbit plane (xOs)xO +(zOs)zO. The beta angle β is defined as the angle between the orbit WebAs can be expected, the overall temperature of the spacecraft becomes higher as the beta angle increases. The satellite spends less time in eclipse at higher beta angles, so heating …
