Equatorial orbit

Equatorial orbit is the orbit over the equator. The inclination of this orbit is 0°.

AstroSat satellite​

AstroSat is the first specialized Indian astronomy mission made for learning celestial source in x-ray, optical and UV ranges (picture 1). One of the unique features of AstroSat mission is that it could make multi-wavelength observations of different astronomical objects with the help of the one satellite. AstroSat with a weight 1515 kg was launched in 2015 year on the orbit 650 km with inclination 6° to equator – that is almost the equatorial orbit.

Agile satellite​

Agile satellite (in Italian «Astrorivelatore Gamma a Immagini Leggero») was launched in 2007 year and made for observation of the universe in Gamma-radiation (picture 2). The key scientific goals are including monitoring of active galactic nuclei, gamma-ray bursts, source of x-ray and gamma-rays in galaxy, unidentified sources of gamma-rays. The satellite’s orbit is almost equatorial – the inclination is 2°.

Add AstroSat satellite with the NORAD ID 40930 or add Agile satellite by the NORAD ID 31135.

Their orbits is almost going over the equator (picture 3):
