IONOSPHERE PROPAGATION DELAY MEASUREMENT TECHNIQUES USING DUAL PHASE COHERENT DOPPLER FREQUENCIES AND A THIN SHELL MODEL.
Abstract
A theoretical approach was made to developing a technique for approximating the time error of a signal from a satellite caused by free electrons reducing the electromagnetic propagation speed. The development involved the use of the Transit satellites' dual frequency transmissions at 400 and 150 MHz, the AN/SRN-9 receiver, and a knowledge of the orbital location of the satellite. The technique gives a reasonably close delay measurement for a given satellite at a given time under a given ionospheric condition. (Author)
