چکیده

Future IGS receivers are considered against the backdrop of GNSS signal modernization and the IGS’s goal of further improving the accuracy of its products. The purpose of this paper is to provide IGS members with a guide to making decisions about GNSS receivers. Modernized GNSS signals are analyzed with a view toward IGS applications. A schedule for minimum IGS receiver requirements is proposed. Features of idealized conceptual receivers are discussed. The prospects for standard commercial receivers and for software-defined GNSS receivers are examined. Recommendations are given for how the IGS should proceed in order to maximally benefit from the transformation in GNSS that will occur over the next decade.

Iranian Permanent GPS Network Receivers Differential Code Biases Estimation Using Global Ionospheric Maps

Measurements of the dual frequency Global Positioning System (GPS) receivers can be used to calculate the electron density and the total electron content (TEC) of the ionosphere layer of the Earth atmosphere. TEC is a key parameter for investigating the ongoing spatial and temporal physical process of the ionosphere. For accurate estimation of TEC from GPS measurements, GPS satellites and GPS r...

Precise Point Positioning for timing

In recent years, many national timing laboratories have installed geodetic Global Positioning System receivers together with their traditional GPS/GLONASS Common View receivers and Two Way Satellite Time and Frequency Transfer equipments. Many of these geodetic receivers operate continuously within the International GNSS Service (IGS), and their data are regularly processed by IGS Analysis Cent...

Evaluation of Dual-Frequency GBAS Performance using Data from Public Receiver Networks

This paper examines the effectiveness of two proposed methods for dual-frequency smoothing in Ground Based Augmentation Systems (GBAS) based on data collected in 2010 by clusters of nearby receivers whose measurements are publically available. After an extensive search turned up no ionospheric anomalies, data from several clusters of CORS and IGS stations under nominal conditions was examined, ...

Comparing Long Baseline Results from GPS and GPS/GLONASS

Abstract: The availability of GLONASS would bring significant benefits to geodetic applications of global positioning systems. GPS and GLONASS observations could be combined directly in the data processing; as a result, the geometry of observed satellites could be enhanced by increasing the number of available satellites. Up to now, with the recent revitalization of GLONASS, more high precision...

Improved Modeling of Global Ionospheric Total Electron Content Using Prior Information

The Ionosphere Working Group of the International GNSS Service (IGS) has been a reliable source of global ionospheric maps (GIMs) since 1998. Modeling of the global ionospheric total electron content (TEC) is performed daily by several Ionosphere Associate Analysis Centers (IAACs). Four IAACs (CODE, ESA, CAS and WHU) use the spherical harmonic (SH) expansion as their primary method for modeling...
