Dataset of MEO (Medium Earth Orbit) Satellites in Space
This dataset contains 139 entries.

  Overview

This is a dataset of MEO satellites, based on UCS Satellite Database compiled by the Union of Concerned Scientist (UCS).

Most MEO satellites are launched for military and commercial use (45.3%) and for the purpose of navigation and global positioning (83.5%).

  What is the most common type of satellite orbit?

Non-Polar Inclined orbit is the most common type of orbit (94 satellites - 67.6%).

  Apogee, Perigee & Period

The perigees (point of the orbit closest to the Earth's center of mass) of the satellites range from 1,885km to 23,551km, with the average perigee being 18,708.8km from the Earth, while the apogees (point of the orbit farthest from the Earth's center of mass) of the satellites range from 2,165km to 23,618km, with the average apogee being 18,864.5km from the Earth. The longest period a satellite takes to orbit around the Earth is 861 minutes.

  Satellite Mass

The launch masses (include fuel) of the satellites range from 600kg to 3,800kg, while the dry masses (excluding fuel) of the satellites range from 280kg to 980kg.


Highlights on some of the military and commercial satellites:

Galileo FOC FM19.

Galileo: the first ten years

  Heaviest satellite launched by Ariane 5 ES into space at 715 kg

Designed for navigation and global positioning, Galileo FOC FM19 is a commercial satellite operated by European Space Agency (ESA) (ESA).

Delivered via Ariane 5 ES (launch vehicle) from Guiana Space Center, it was launched into space on 25 July 2018 and orbits the Earth as a non-polar inclined MEO satellite. Galileo FOC FM19 was constructed by OHB-System GmbH, SSTL (Germany/UK).

Designed with an operational lifetime of 12 years, Galileo FOC FM19 has a launch mass of 715 kg and navigates with the COSPAR ID 2018-060C and NORAD ID 43566.

Taking 840 minutes to orbit the Earth, the satellite's perigee, which is the point of the orbit closest to the Earth's center of mass, is 23,233km while its apogee, which is the point of the orbit farthest from the Earth's center of mass, is 23,250km. The eccentricity of the orbit is 2.87E-04 and it orbits at an inclination of 56 degrees to the equatorial plane of the Earth.

O3b FM09.

O3b's 3rd Set of Satellites Successfully Launched

  Second heaviest equatorial satellite launched into space at 650 kg

A commercial satellite, O3b FM09 is operated by O3b Networks Ltd. of United Kingdom for the purpose of communications.

Constructed by Thales Alenia Space (France), it was launched into space using Soyuz-ST-B as the launch vehicle from Guiana Space Center on 18 December 2014. O3b FM09 orbits around the Earth as a equatorial MEO satellite.

O3b FM09 has a launch mass of 650 kg and navigates with the COSPAR ID 2014-083D and NORAD ID 40351.

With an orbital eccentricity of 1.73E-04, the satellite's perigee, which is the point of the orbit closest to the Earth's center of mass, is 8,063km while its apogee, which is the point of the orbit farthest from the Earth's center of mass, is 8,068km. O3b FM09 takes 288 minutes to orbit the Earth with its self-generated usable power of 1500 watts.
