← ScienceWhich phenomenon limits GPS accuracy at high orbital speeds?
A)Relativistic time dilation✓
B)Signal multipath interference
C)Atmospheric signal degradation
D)Hardware clock limitations
💡 Explanation
The high speeds cause relativistic time dilation, where time passes slower on faster objects per mass-energy equivalence; therefore GPS signals are delayed because satellite time lags compared to ground time, rather than errors in the clock itself.
