How are measurements done in the Doppler Orbitography Radiopositioning integrated by satellite.Please tell in detail.Or books related to it.
The DOR system measures the position of objects by analyzing the Doppler shift in radio signals received from satellites. This shift is caused by the movement of the object in relation to the satellite, allowing for precise determination of the object's position.
DOR is primarily used for tracking satellites and other space debris, as well as for measuring the positions of planets and other celestial bodies. However, it can also be used to track aircraft, ships, and other moving objects on Earth.
The DOR system is highly accurate, with a margin of error of less than 10 meters for satellites in low Earth orbit. For objects in higher orbits, the margin of error may be slightly higher, but still within a few meters.
Yes, the DOR system relies on specialized ground-based antennas and receivers, as well as satellites equipped with precise atomic clocks. These components work together to accurately measure the Doppler shifts in radio signals and calculate the position of tracked objects.
Yes, DOR can be used for real-time tracking and navigation, as it provides continuous updates on the position of tracked objects. This makes it a valuable tool for applications such as satellite navigation and space situational awareness.
