The Bharatiya Antariksh Station (BAS), India's planned space station, is proposed to orbit at what approximate altitude above the Earth's surface?
400-450 km
The Bharatiya Antariksh Station (BAS) is ISRO's planned space station; its first module (BAS-1) is targeted for 2028 and the full station by 2035.
Like the International Space Station, it is planned for low Earth orbit, at an altitude of about 400–450 km above the Earth's surface.
200–250 km is too low for a long-lived station because of atmospheric drag, while 600–900 km is beyond the planned range.
Hence, 400-450 km.
