Abstract (sommario):

Abstract Global Positioning System (GPS) technology is ideally suited for inshore and offshore positioning because of its high accuracy and the short observation time required for a position fix. Precise point positioning (PPP) is a technique used for position computation with a high accuracy using a single GNSS receiver. It relies on highly accurate satellite position and clock data that can be acquired from different sources such as the International GNSS Service (IGS). PPP precision varies based on positioning technique (static or kinematic), observations type (single or dual frequency) and

Abstract (sommario):

The orbital inclination angle of the GLONASS constellation is about 10° larger than that of GPS, Galileo, and BDS. Theoretically, the higher orbital inclination angle could provide better observation geometry in high latitude regions. A wealth of research has investigated the positioning accuracy of GLONASS and its impact on multi-GNSS, but rarely considered the contribution of the GLONASS constellation’s large orbit inclination angle. The performance of GLONASS in different latitude regions is evaluated in both stand-alone mode and integration with GPS in this paper. The performance of GPS is

Abstract (sommario):

International time transfer based on Global Navigation Satellite System (GLONASS) precise point positioning (PPP) is influenced by inter-frequency code biases (IFCBs) because of the application of frequency division multiple access technique. This work seeks to gain insight into the influence of GLONASS IFCBs on international time transfer based on GLONASS-only PPP. With a re-parameterization process, three IFCB handling schemes are proposed: neglecting IFCBs, estimating IFCB for each GLONASS frequency number, and estimating IFCB for each GLONASS satellite.

Abstract (sommario):

Because GLONASS and GPS are different in system, data processing of GLONASS carrier phase difference is quite different from that of GPS, requiring special methods. Based on eliminating the impact of the relative deviation of receiver clock, a new mathematical model of GLONASS phase difference is introduced in this article. This new model can make full use of existing GPS data processing technology to complete GLONASS data processing work conveniently.

AbstractGLONASS, successfully operating during 1990s became unusable by early 2000s. Following a revitalization and modernization plan since 2004, GLONASS constellation has been completed again by the end of 2011 and the use of GLONASS is gaining popularity. Because of the previous experience, some scepticism exists among the stakeholders in using GLONASS for reliable solution and application development. This paper critically reviews the operational lifespan of GLONASS satellites launched between 2004 and 2016, as this is an important contributor towards reliability and sustained operation of

Ground displacements due to ocean tide loading have previously been successfully observed using Global Positioning System (GPS) data, and such estimates for the principal lunar M2 constituent have been used to infer the rheology and structure of the asthenosphere. The GPS orbital repeat period is close to that of several other major tidal constituents (K1, K2, S2); thus, GPS estimates of ground displacement at these frequencies are subject to GPS systematic errors.

Abstract (sommario):

En los últimos años, ha habido un incremento en el número de satélites disponibles para posicionamiento mediante técnicas espaciales, donde se destacan los sistemas GPS y GLONASS. Se realizó el análisis comparativo de los resultados obtenidos tras el cálculo de una red de estaciones GNSS en Europa, a partir del procesamiento de los datos usando el programa Bernese 5.2 que, entre otras cosas, destaca por presentar una mejora en el tratamiento conjunto de datos GPS y GLONNAS, con respecto a la versión anterior del programa. El fin primario que motivó la investigación es la necesidad de determina

Abstract (sommario):

Abstract Precise point positioning (PPP) is a GNSS positioning technique that saves cost and has an acceptable accuracy for enormous applications. PPP proved its efficiency through two decades comparing with traditional differential positioning technique. PPP uses one receiver collecting observations at an unknown station without the need for a reference station with known coordinates. PPP-collected observations must undergo extensive mitigation of different GNSS errors. Static-PPP accuracy depends mainly on the observations type (dual or single frequency), used systems (GPS or GLONASS or mixe

Abstract (sommario):

O GLONASS (GLObal NAvigation Satellite System) e o GPS (Global Positioning System) são os sistemas pioneiros de navegação global por satélite. A utilização combinada de dados GPS e GLONASS despertou interesse inicialmente, mas as pesquisas com investigação de ambos os sinais diminuíram muito no final da década de noventa devido à rápida degradação que o GLONASS sofreu. Porém, após um plano de restabelecimento do sistema, em 2011 o GLONASS voltou a contar com constelação completa e cobertura global. Além do restabelecimento, o sistema passou ainda por um processo de modernização, com novas gera

The principal characteristics of the GLONASS system, its current status and deployment outlook are considered. Comparison of the main characteristics of the GPS/GLONASS systems from the user's viewpoint is made. Proposals focused on the operations to be carried out to improve navigation determination accuracy for the users, provided with the combined equipment, are given. The data presented, received simultaneously on the user&s GLONASS equipment and a GP–500 GPS system, indicate that navigational determination accuracies of both systems are approximately equal.

This analysis gives a clear picture of the evolution of methods for shaping navigation radio signals and provides insights into their advantages and disadvantages. Special attention is paid to group navigation signals of the GLONASS system, which appear in the next generation of GLONASS navigation spacecraft to optimize the antenna assembly. The peculiarities of shaping them are considered, taking account of ensuring code measurement accuracy and effect

Abstract (sommario):

Global Positioning System (GPS), Global Navigation Satellite System (GLONASS), and GPS-GLONASS receivers are commonly used for navigation. However, there are some applications where a single antenna interface to a GPS or GPS-GLONASS receiver will not suffice. For example, an airborne platform such as an Unmanned Aerial Vehicles ( UAV ) will need multiple antennae during maneuvering. Also, some applications will need redundancy of antenna connectivity to prevent loss of positioning if a link to satellite fails. The scope of this work is to design a dual antenna GPS-GLONASS navigation receiver a

Apesar de os dois sistemas terem obtido constelações completas em períodos próximos, o GLONASS passou por um longo período de degradação, causada principalmente pela falta de investimentos e lançamentos para substituição de satélites mais antigos. Com isso o uso de dados combinados GPS/GLONASS acabou se tornando inviável já no

Abstract (sommario):

Precise Point Positioning (PPP) with Global Positioning Systems (GPS) has attracted the attention of many researchers over the past decade. Recently, the Russian global navigation satellite system (GLONASS) has been modernized and restored to near full constellation status, which has made it more attractive for positioning and navigation. Having two healthy systems, namely GPS and GLONASS provides a combination of both constellations, which in turn promises to improve the availability, positioning accuracy, and reliability of PPP solutions.
