Introduction,space vehicles (20–100?km in altitude), and spacecrafts (greater than 100?km in altitude). Those flying at an altitude of more than 2?×?10.?km are also known as deep-space vehicles. Specifically, the flight vehicles include missiles, satellites, spaceships, space stations, deep-space probes, near-sp

Spread Spectrum TT&C,n 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 info

Special Issues on Radio Transmission Channel in C&T,tromagnetic signals in free space (in a broad sense, it may include related components and links). Radio transmission channel may bring in many adverse impacts on C&T signals, such as orbit-determining error and signal attenuation caused by radio wave transmission characteristics, multipath interfer

Book 2015nd information transmission. Combining TT&C and information transmission, the book presents several technologies for continuous wave radar including measurements for range, range rate and angle, analog and digital information transmissions, telecommand, telemetry, remote sensing and spread spectrum

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.
