AbstractA phase-coherent and frequency-hopped PN ranging system was developed, originally for the purpose of anti-jamming TT&C (tracking, telemetry and telecommand) of military satellites of China, including the Beidou-2 navigation satellites. The key innovation in the synchronization of this system is the unambiguous phase recovery of direct sequence and frequency hopping (DSFH) spread spectrum signal and the correction of frequency-dependent phase rotation caused by ionosphere. With synchronization achieved, a TEC monitoring algorithm based on maximum likelihood (ML) principle is proposed and its measuring precision is analyzed through ground simulation, onboard confirmation tests will be performed when transionosphere DSFH links are established in 2014. The measuring precision of TEC exceeds that obtained from GPS receiver data because the measurement is derived from unambiguous carrier phase estimates, not pseudorange estimates. The observation results from TT&C stations can provide real time regional ionosphere TEC estimation.

The features of using survey GNSS receivers for real-time ionosphere monitoring based on high orbital ionosphere tomography network are presented. The related problems and solutions methods are described. The algorithms for calculating total electron content and scintillation indices, that allow reducing errors and noise, are proposed. Special attention is given to the methods reducing data loss during processing. A model of the electron content peak height used for mapping ionospheric parameters is also introduced.
