Orbital plane flips, a transition from prograde to retrograde motion or vice versa, is a phenomenon due to solar radiation pressure that is investigated. We consider initial near-circular orbits with different inclinations, including the vicinity of orbits of the GNSS satellites, GEO, geosynchronous orbits, and super-GEO region. Dynamical evolution of orbits is studied from a ...

The paper is devoted to a radical way to increase vibration resistance of global navigation satellite systems (GNSS) signal receivers (GLONASS, GPS, etc.). The method is based on the use of a common (quartz) loop in addition to individual loops– traditional for GNSS receivers phase locked loops (PLL), each of which monitors a separate radio ...

Modern global navigation satellite systems (GNSS) receivers use temperature-compensated crystal oscillators (TCXO) as generators of reference frequency. One of the parameters of quartz oscillators is its stability to output frequency when oscillators are subject to acceleration and vibrations. Such a stability is assessed by g-sensitivity value. Relatively high g-sensitivity of quartz oscillators can result in ...

Different dynamic and noise characteristics of hardware-software systems of phase lock loops (PLL) within global navigation satellite systems (GNSS) receivers capable of operating under strong dynamic external effects have been considered in the present paper. Most operations in hardware-software systems are performed in processor at relatively low rate of time discretization, the signals of many ...

This paper is a continuation of the author’s previous study on methods of velocity measurements of navigation receivers and devoted to their comparative analysis.
Each method of measuring velocity has a few parameters. Let us fix all parameters except for one (main) and vary this parameter. The value of each varied parameter corresponds to some noise error of velocity measurements which ...

Measurements of velocity in navigation receivers are performed in two stages. At the primary (after-satellite)
processing stage each of received signals is synchronized using a separate PLL, after that an estimation block (EB) estimates nonenergy (phase and frequency) and energy (SNR) parameters of the received signal. Doppler primary estimations can be subject to after-satellite filtration to obtain secondary frequency estimates. A ...

The present paper discusses different techniques of measuring Carrier-to-Noise density ratio (C/N0) in navigation and information-communication systems. C/N0 means the ratio of the received signal power to the noise spectral density N0 at receiver's input (at the output of an antenna with a low-noise amplifier (LNA)). Correlation processing is performed in the receiver to obtain in-phase (I) ...

Приемники глобальных навигационных спутниковых систем (ГНСС) принимают и обрабатывают множество сигналов от навигационных спутников систем GPS (США), ГЛОНАСС (РФ) и др. Каждый из N сигналов обрабатывается в отдельном канале, при этом в каждом канале на этапе первичной обработки производится фазовая синхронизация и оценка неэнергетических (фаз и частот) и энергетических параметров принимаемого сигнала. Совокупность этих оценок ...

A subject of the study are systems of synchronization and motion parameters estimation for global positioning satellite systems (GLONASS, GPS, Galileo and others) receivers. Two synchronization systems are considered in the paper: a traditionally used system with separate synchronization in each navigation channel and an alternative one – with joint synchronization of all the signals. ...
