Abstract

Spread spectrum is an information transmission technology. The spread spectrum TT&C system is a system which realizes TT&C and information transmission using direct sequence (DS) spread spectrum, frequency hopping (FH) spread spectrum, time hopping (TH) spread spectrum or any combination of them. PN codes are the typical spread spectrum signals. For example, PN codes in a DS TT&C system are used for spread spectrum of telemetry & telecommand information and for integration of ranging signals and information. With respect to the orbit-measuring function, the system also uses PN codes for ranging and carriers for Doppler velocity-measuring, and then conducts angle tracking for the carrier signals after spread spectrum by PN codes.
