[Termes IGN] GPS-INSRésumé : (Auteur) The design of optimal inertial/GNSS integrated navigation systems begins with the calculation or the estimation of the lower bound of the system before its development. This article has looked at various ways of obtaining an approximation to the CRLB. It is hoped that online approximation of these lower bounds may soon be applied to modern non-linear filtering approaches.

[Termes IGN] orientation du capteur intégréeRésumé : (Auteur) Over the past two decades, the development of Global Navigation Satellite System (GNSS) technology, inertial navigation technology and Inertial Navigation Systems (INS) and their application to sensor orientation in photogrammetry and remote sensing has led to more precise, accurate, reliable and cost efficient orientation and calibration methods and procedures. Today, most airborne photogrammetric and remote sensing systems are equipped with GNSS receivers and inertial sensors. To a large extent and more or less independently from the imaging geometry and sensor type, orientation is performed with the “direct” and “integrated” methods. In this paper we introduce a new orientation method that we call “Fast AT” for frame images. The new method combines image measurements, ground control and aerial control observations in novel quantitative and qualitative ways. Depending on project specifications, Fast AT can be a robust alternative to direct orientation and, at the very least, a fast quality control tool for any orientation task. We analyze the performance of Fast AT with analogue and digital frame imagery and draw conclusions on its general properties.

[Termes IGN] traitement du signalRésumé : (Auteur) To reliably navigate with fewer than four satellites, GPS pseudoranges need to be augmented with measurements from other sensors, such as a reduced inertial sensor system or RISS. What is the best way to combine the RISS measurements with the GPS measurements? The classic approach is to integrate the measurements in a conventional tightly coupled Kalman filter. But in this month’s column, we look at how a mathematical procedure called parallel cascade identification can improve the Kalman filter’s job, when navigating with three, two, or even one GPS satellite.

[Termes IGN] test de performanceRésumé : (Auteur) Combining data from a Strapdown Inertial Navigation System and a Differential Global Positioning System (SINS/DGPS) has shown great promise in estimating gravity on moving platforms. Previous studies on a ground-vehicle system obtained 1–3 mGal precision with 2 km spatial resolution. High-accuracy Inertial Measurement Units (IMU) and cm-level positioning solutions are very important in obtaining mGal-level gravity disturbance estimates. However, these ideal configurations are not always available or achievable. Because the noise level in the SINS/DGPS gravimetric system generally decreases with an increase of speed and altitude of the platform, the stringent constraints on the IMU and GPS may be relieved in the airborne scenario. This paper presents an investigation of one navigation-grade and one tactical-grade IMU for the possibility of low-cost INS/GPS airborne gravimetry. We use the data collected during the Gravity-Lidar Study of 2006 (GLS06), which contains aerogravity, GPS, and INS along the northern coastline of the Gulf of Mexico. The gravity disturbance estimates from the navigation-grade IMU show 0.5–3.2 mGal precision compared with the onboard gravimeter’s measurements and better than 3 mGal precision compared with the upward continued surface control data. Due to relatively large (240 s) smoothing window, the results have about 34 km along-track resolution. But the gravity estimates from the tactical-grade IMU have much poorer precisions. Nonetheless, useful contributions from the tactical-grade IMU could be extracted for longer wavelengths.

[Termes IGN] traitement d'image radarRésumé : (Auteur) The objective of the research study is to use the synergy of 3D empirical (Rational Function Model (rfm) and physical (Toutin's) geometric models to develop a "new hybrid" model for the geometric processing of Radarsat-2 data without collecting ground control point (GCP). After independently evaluating the processing and the accuracy of each model using accurate differential GPS points, RFM was thus used to generate few "virtual" rfm points at the highest elevation of the study site. In addition to information of the metadata, these "virtual" points were input as GCPs in Toutin's model. This new hybrid model consistently achieved pixel accuracy, with better results for steep looking angles than the two other models. Its main advantage was, in addition, to be used without collecting GCP, increasing the applicability of Radarsat-2 data in remote areas.
