  • communication satellite - Why 53º orbits for Starlink? - Space . . .
    The idea is that inclined orbits spend most of their time above latitudes that are near their inclination Let's say you can talk with a Starlink satellite as long as it's 30° above the horizon A 60° degree half-angle cone from a satellite 400 km above the Earth has a radius of 700 km, which is about + - 6° in latitude
  • Orbital inclination - Wikipedia
    An inclination of 0° means the orbiting body has a prograde orbit in the planet's equatorial plane An inclination greater than 0° and less than 90° also describes a prograde orbit An inclination of 63 4° is often called a critical inclination, when describing artificial satellites orbiting the Earth, because they have zero apogee drift [3]
  • The Nuances of the 53-Degree Starlink Shells - rfi. colem. co. uk
    Starlink satellites orbiting with ~53 degrees of inclination are of prime importance to SpaceX for several reasons: • It is where it all started (first shell uses 550 km of altitude and 53 degrees of inclination) • Currently, around 60% of all Starlink satellites orbit with an inclination of 53 to 53 25 degrees
  • Starlink has a lot of (most?) satellites at an orbital inclination of . . .
    Starlink has a lot of (most?) satellites at an orbital inclination of 53 degrees to avoid "wasting" time over the poles where few people live while still providing coverage at most other latitudes This means that at any time there's a higher density of satellites above that latitude than at the equator
  • Section 4. 3 - The Six Orbital Elements - Astronomical Returns
    Inclination ($i$) Inclination is the angle between the orbital plane of the satellite and the equatorial plane I'll go ahead and introduce the concept of nodes, since we'll need them for the next orbital element anyway
  • Orbital inclination | National Aeronautics and Space Administration . . .
    Orbital inclination is the minimum [Clarification needed] angle between a reference plane and the orbital plane or axis of direction of an object in orbit around another object The inclination is one of the six orbital parameters describing the shape and orientation of a celestial orbit
  • Inclined orbit satellite operation - satsig. net
    If left alone, a satellite that has initial zero inclination will have its inclination increase at the rate of 0 8 deg per year It is usual not to let the maximum north-south movements exceed + - 0 15 degree to allow the use of large numbers of fixed pointing moderate sized and VSAT antennas
  • Lecture 2: Satellite Orbits - University of Arizona
    define a satellite orbit (essentially 3D velocity and 3D position at a specified time), from our perspective, the main features of an orbit are its radius or altitude, orbital period, orbital velocity, inclination, times of day crossing the equator (“longitude of the ascending node”) and precession rate These are not independent of one
  • Flight Dynamics - NASA
    "A satellite in an orbit with a zero-degree inclination flies directly above the earth's equator at all times These orbits are called "equatorial orbits" " Single satellite orbiting the earth with a 51 6 deg inclination (viewpoint: moving toward the side of the ascending node and then the descending node);
  • SPECIFYING SATELLITE ORBITS - Space Academy
    However, in specifying the orbital elements of a satellite it is more usual to specify the time at which the satellite passes the perigee (t p or t 0), and then to use orbital mechanics (based on Newton's law of gravitation) to compute the actual position around the orbit
