Scintillation limitations on the 2nd-phase-difference range measurement
Abstract
The 2nd-phase difference range-measurement technique allows a real-time correction to be made for the excess propagation time delay introduced by the ionosphere in the overall transit time between the earth station and the spacecraft. The value of the second phase difference is partly random, due largely to ionospheric phase scintillations. The effect of ionospheric phase scintillations on the rms range imprecision is investigated.
