[Termes IGN] positionnement par GNSSRésumé : (auteur) This chapter is organized into three parts. The first part is an introduction to space geodesy, the principles of global navigation satellite system (GNSS) geodesy, and the International Association of Geodesy (IAG). The IAG is the scientific association that organizes the space geodetic services that support high‐accuracy GNSS positioning for scientific and societal applications. The most important of the IAG services is the International GNSS Service (IGS), and the second part of the chapter provides a short description of the IGS and its role in providing the geodetic infrastructure and services that underpin precision GNSS positioning. The third part describes one of the most important products of modern geodesy, the Terrestrial Reference Frame (TRF). The chapter also provides a brief explanation of how the International TRF is realized, including some information on the current ITRF2014.

[Termes IGN] traitement de données GNSSRésumé : (auteur) High-precision single-receiver positioning requires the provision of reliable network-derived corrections. Care must therefore be exercised to continuously check the quality of the corrections and to detect the possible presence of mis-modeled biases in the network data. In network-RTK or its state-space implementation, PPP-RTK, quality control of the solutions is executed in two separate phases: the network component and the user component. Once confidence in the network-derived solutions is declared, a subset of the solutions is sent as corrections to a single-receiver user, thereby allowing the user to separately check the integrity of his network-aided model. In such a two-step integrity monitoring procedure, an intermediate step is missing, the integrity monitoring of the corrections themselves. It is the goal of this contribution to provide a quality control procedure for GNSS parameter solutions at the correction level, and to measure the impact a missed detection bias has on the (ambiguity-resolved) user position. New detection test statistics are derived with which the single-receiver user can check the overall validity of the corrections even before applying them to his data. A small-scale network of receivers is utilized to provide numerical insights into the detectability of mis-modeled biases using the proposed detectors and to analyze the impact of such biases on the user positioning performance.
