The Thumba Equatorial Rocket Launching Station (TERLS) is an Indian spaceport operated by the Indian Space Research Organisation. It is located in Thumba, Thiruvananthapuram which is near the southern tip of mainland India, very close to earth's magnetic equator. It is currently used by ISRO for launching sounding rockets.
Thumba is located very close to the magnetic equator of the Earth (located just north of Thumba), making it the ideal location for scientists to conduct atmospheric research. In fact, Thumba's location at 8°32'34" N and 76°51'32" E is ideal for low-altitude, upper atmosphere and ionosphere studies. Thumba is a small fishing village situated close to the Thiruvananthapuram airport in Kerala. Thumba is also one of the farthest points from Pakistan, China and Bangladesh
