Which mechanism causes lengthening signal delays across Earth-orbiting satellites?

💡 Explanation

Gravitational time dilation causes signal delays because general relativity dictates variations in spacetime near massive bodies; therefore, light traveling through stronger gravitational fields experiences Shapiro delay, rather than solely atmospheric effects or Doppler shifts because those are independent phenomena.
