Science

Which risk increases when operating a GPS satellite near Earth and why does the principle matter?

A)Signal desynchronisation from relativistic time dilation
B)Excessive power drain affects transponders
C)Antenna misalignment causes data corruption
D)Atomic clock failure biases positioning accuracy

💡 Explanation

Accuracy degrades severely because relativistic time dilation means the satellite's clock runs faster than Earth's; General Relativity requires adjusting via the Einstein synchronisation mechanism; therefore, ignoring it increases positional errors sharply, rather than electrical load or component failures.
