Title: All in motion: Satellite geodesy its past and future
Biography: Yuksel Altiner
The era of satellite geodesy began with the reception of the signal from the Russian satellite Sputnik on the earth's surface on October 4, 1957. That was the first satellite ever in space. On July 21, 1969, the American astronaut Armstrong became the first human to walk on the Moon. Between these two important events lies a time difference of only about 10 years. Today, there are so many satellites in space that pose a serious threat even to the world. This presentation focuses on the accuracy of navigation and positioning obtained using different satellite constellations and asks if we need so many satellites in space for our everyday personal and professional use or is this a fierce competition between the so-called great powers?
