By 2020, the BeiDou orbital constellation will include 35 satellites:

• 5 BeiDou-G satellites in the geostationary orbit (GEO) (58.75° E, 80° E, 110.5° E, 140° E and 160° E);
• 27 BeiDou-M satellites in medium Earth orbit (MEO) (in three planes with the nominal altitude of 21 528 km and nominal period of 12 hours 53 min inclined at 55° relative to the equator);
• 3 BeiDou-I satellites in inclined geosynchronous orbits (IGSO) with the altitude of 35 786 kilometers and an inclination of 55° to the equatorial plane. The sub-satellite tracks for those satellites coincide while the longitude of the intersection point is at 118°E.
