The use of the US Navy Navigation Satellite System (NNSS) for the determination of the ionospheric ectron content up to the height of the satellite (36 000 km) with an accuracy 5 % . If by means of actual simultaneous measurements, e.g. using beacons of low orbiting satellites, one can determine the total electron content up to 1100 km height with roughly the same accuracy, one ca

Summary,orbiting US-NNSS satellites provide a good possibility to determine the ionospheric electron content up to 1100 km fairly accurately by evaluating the Dispersive Doppler recordings obtained at 150 MHz and 400 MHz.

69. Now the five orbiting FS-NNSS satellites provide a good possibility to determine the ionospheric electron content up to 1100 km fairly accurately by evaluating the Dispersive Doppler recordings obtained at 150 MHz and 400 MHz. The amplitude recordings of the 40 MHz and 41 MHz signals of Explorer 22 were f978-3-540-05893-9978-3-642-65425-1
