It is a multi-use, space-based radio-navigation system, embracing defense and security, civil, commercial, and scientific research needs. Taking into account the importance of the system, it has been suggested to present current advances of GPS with attention focused on vital aspects of technology. This book provides a general description of GPS, GNSS, and GLONASS with reference to the improvement of characteristics of the segments, including software applications and the equipment itself containing GPS. The book also provides information on application areas. Equally, a number of common shortcomings and errors are described, and elimination and mnimization of such consequences are demonstrated.

J’ai travaillé dans les locaux de la direction de la recherche et de l’innovation sous la tutelle de M. José DEVERS. L’objectif du projet est d’esquisser la mise en place d’une communauté d’acteurs et d’utilisateurs d’applications satellitaires. Pour ce faire, en plus d’assister mon tuteur lors de réunions, de déplacements, d’appels téléphoniques et de conférences, j’ai été chargé plus particulièrement :
- de me familiariser avec l’organisation et les missions du MTES puis avec les Plans d’applications satellitaires des MTES et MCT (Ministère de la Cohésion des Territoires). J’ai en effet effectué un état de l’art à partir des différents rapports et bilans des PAS précédents et des volontés exprimées de mises en oeuvre du nouveau ;
- de me pencher sur les différentes actions qui ressortaient et qui ont été retenues par les directions générales pour bien comprendre les intérêts des politiques publiques du ministère ;
- de recenser les besoins utilisateurs en rencontrant différents acteurs et utilisateurs des domaines spatial et satellitaire. Je me suis rendu compte de nombreux problèmes de communication et de partage des données et de services qui subsistent encore et toujours entre les acteurs. Il m’a fallu organiser les nombreux besoins qui ont émané des rencontres, les analyser puis chercher à apporter des solutions existantes aux problématiques de chacun ;
- d’étudier des communautés existantes pour comprendre au mieux leur fonctionnement, leurs avantages et leurs inconvénients et chercher celui ou ceux qui seraient le(s) plus adapté(s) à notre future communauté ;
- de préparer un atelier rassemblant des acteurs, des utilisateurs et des non-initiés au domaine satellitaire pour discuter autour de l’aspect purement fonctionnel de la communauté.
Finalement, je suis parvenu à démontrer l’intérêt d’une telle communauté et élaborer deux scénarios possibles de réseau qui pourraient répondre au mieux aux besoins.Note de contenu : Introduction

[Termes IGN] teneur verticale totale en électronsRésumé : (Auteur) GPS Differential Code Biases (DCBs) computation is usually based on ground networks of permanent stations. The drawback of the classical methods is the need for the ionospheric delay so that any error in this quantity will map into the solution. Nowadays, many low-orbiting satellites are equipped with GPS receivers which are initially used for precise orbitography. Considering spacecrafts at an altitude above the ionosphere, the ionized contribution comes from the plasmasphere, which is less variable in time and space. Based on GPS data collected onboard JASON-2 spacecraft, we present a methodology which computes in the same adjustment the satellite and receiver DCBs in addition to the plasmaspheric vertical total electron content (VTEC) above the satellite, the average satellite bias being set to zero. Results show that GPS satellite DCB solutions are very close to those of the IGS analysis centers using ground measurements. However, the receiver DCB and VTEC are closely correlated, and their value remains sensitive to the choice of the plasmaspheric parametrization.

[Termes IGN] teneur totale en électronsRésumé : (Auteur) Ionospheric delay is a dominant factor that affects the accuracy of single-frequency positioning. Thus, an empirical ionospheric model with high accuracy is very important for single-frequency users. This study proposes a modified empirical broadcast ionospheric model, called MNTCM-BC, based on the Neustrelitz Total Electron Content (TEC) broadcast model NTCM-BC. Nine daily ionospheric coefficients of these models are estimated using datasets of the previous day from 30 globally distributed Global Navigation Satellite System monitor stations, and the prediction performance of the MNTCM-BC is evaluated with the datasets of the current day from all 300 verification stations. The results show that the complex behavior of the ionosphere is well described by the MNTCM-BC, including the visibility of two ionization crests on both sides of the geomagnetic equator and the TEC variations that depend on the local time and geomagnetic latitude. In terms of the prediction accuracy, compared with the NTCM-BC, the main improvement in the MNTCM-BC is achieved in summer, whereas the accuracy is comparable in other seasons. Hence, the following analyses are focused on summer. In the low-solar activity year of 2009, the prediction accuracy of the MNTCM-BC is improved by 0.11 TECU compared with that of the NTCM-BC. As to the high-solar activity year of 2014, the corresponding improvement is 0.35 TECU. In addition, when the number of monitor stations is increased from 30 to 300, the prediction accuracy of two models can be slightly improved by 0.06 TECU in 2009 and 0.13 TECU in 2014, respectively, while reliability enhances. Furthermore, the average three-dimensional positioning accuracy of 160 globally distributed stations for single-frequency point positioning using the Klobuchar model, the NTCM-BC and the MNTCM-BC is 1.83, 1.21 and 1.20 m during quiet day and 3.15, 2.31 and 2.21 m during perturbed day, respectively. Relative to the Klobuchar model and the NTCM-BC, the average accuracy improvements in the MNTCM-BC are about 30 and 3%, respectively.

[Termes IGN] teneur totale en électronsRésumé : (Auteur) Global Navigation Satellite Systems (GNSS) require mitigation of ionospheric propagation errors because the ionospheric range errors might be larger than tens of meters at the zenith direction. Taking advantage of the frequency-dispersive property of ionospheric refractivity, the ionospheric range errors can be mitigated in dual-frequency applications to a great extent by a linear combination of carrier phases or pseudoranges. However, single-frequency GNSS operations require additional ionospheric information to apply signal delay or range error corrections. To aid single-frequency operations, the global positioning system (GPS) broadcasts 8 coefficients as part of the navigation message to drive the ionospheric correction algorithm (ICA) also known as Klobuchar model. We presented here an ionospheric correction algorithm called Neustrelitz TEC model (NTCM) which can be used as complementary to the GPS ICA. Our investigation shows that the NTCM can be driven by Klobuchar model parameters to achieve a significantly better performance than obtained by the mother ICA algorithm. Our research, using post-processed reference total electron content (TEC) data from more than one solar cycle, shows that on average the RMS modeled TEC errors are up to 40% less for the proposed NTCM model compared to the Klobuchar model during high solar activity period, and about 10% less during low solar activity period. Such an approach does not require major technology changes for GPS users rather requires only introducing the NTCM approach a complement to the existing ICA algorithm while maintaining the simplicity of ionospheric range error mitigation with an improved model performance.
