When Were Geostationary Satellite Invented?

NASA launched the first geosynchronous satellite, Syncom I, on February 14, 1963 but it stopped sending signals due to some technical failures encountered seconds before reaching its final orbit.

When was the first geostationary satellite launched?

Syncom 2, the first satellite in a geosynchronous orbit (an orbit that has a period of 24 hours but is inclined to the Equator), was launched successfully on July 26, 1963, and Syncom 3, the first satellite in geostationary orbit, on August 19, 1964.

How long does a geostationary satellite stay in orbit?

A geostationary orbit can be achieved only at an altitude very close to 35,786 kilometres (22,236 miles) and directly above the equator. This equates to an orbital speed of 3.07 kilometres per second (1.91 miles per second) and an orbital period of 1,436 minutes, one sidereal day.
