Inquire MEASURING RADIAL SPEED AND LOCATION SATELLITE global navigation system GLONASS AND SYSTEM FOR CARRYING OUT

摘要

1. The query method for measuring the radial velocity and the GLONASS satellite navigation system location that requires the use of two objects, the first object to an interrogation signal at a frequency ωmanipuliruyut in phase by 180 ° followed by a pseudorandom maximum length, thus forming a complex signal with phase shift keying, is converted its frequency using a local oscillator frequency ωpervogo, isolated voltage of the first intermediate frequency ω = ω + ω = ω, increase its power emit broadcast at the frequency ω = ω, y avlivayut repeater second object, increase in power is converted in frequency by using frequency ωtretego LO isolated voltage of the second intermediate frequency ω = ω-ω = ω, increase power emit broadcast at the frequency ω = ω, capture request unit of the first object, increase in power, it is converted in frequency by using frequency ωvtorogo LO isolated first voltage third intermediate chastotyω ± 'Ω = ω-ω, multiply and divide it into two phase, is isolated harmonic oscillation at frequency ω ±' Ω, Cf. NIWA its frequency interrogating signal at ω frequency isolated Doppler frequency ± 'Ωi magnitude and sign of the Doppler frequency determined magnitude and direction of the radial velocity, while the composite signal with a phase shift keying in the frequency ωpropuskayut through the first flow adjustable delay, multiply it with the first voltage a third intermediate frequency, allocate a low-frequency voltage, thereby forming a first correlation function R (τ), where τ - current time delay, delay variation τ first support
