What is the distribution of Earth orbiting satellites by inclination? In other words, what inclinations are more or less popular? I work with Earth observation myself, where many satellites are Sun-synchronous with an inclination of around 98°, or Geostationary with an inclination of near 0°. Other orbits exist but are uncommon. Communication satellites also exist as either equatorial (such as satellite TV) or with a high inclination (such as the Iridium constellation). Are there any published statistics on satellite inclination popularity, such as a histogram/PDF of current Earth orbiting satellites by inclination?
It should be trivial to produce such statistics from published TLE files, but I couldn't find any for artificial Earth-orbiting satellites.
Question inspired by some of the discussion around: Are there any known reasons why there are no spaceports in the European Union?
