[Termes IGN] station virtuelleRésumé : (Auteur) Over the past few years, a significant amount of research has been conducted on the information of carrier phase correction in order to enhance ambiguity resolution and to increase the distances over wich precise positioning can be achieved. Recently the use of a network of multiple GPS reference stations for generating carrier phase-based corrections has emerged with great promise for use in real-time environments. However, little research has been conducted on the distribution of these correction to potential GPS users located within, and surrounding, the network coverage area. This is an integrated part of real-time kinematic DGPS, and it must be adequately adressed before a pratical realization of the multi-reference station concept is implemented. The focus of this paper is to present a comprehensive summary of some of the multiple reference station methods, with specific attention directed toward the correction generation and dissemination processes. More specifically, the various multi-reference station methodologies have been categorized according to their underlying correction generation framework, but will be discusse in terms of the correction dissemination options presented by various authors. The four main categories of methods investigated in this paper are : (a) partial derivative algorithms, (b) linear interpolation algorithms, (c) condition adjustement algorithms and (d) virtual reference station methodologies.

The main focus is laid on the analysis of the accuracy potential of a commercially available integrated GPS/INS module using the "standard" approach for direct georeferencing : the integration of continuously recorded GPS and INS data in a Kalman filter approach. This method, originally developed for navigation purposes, is compared to a more straightforward strip-wise approach, which allows, in combination with an imaging sensor, the direct orientation determination even for short time intervals and data segments during photogrammetric strips. Beforehand, the basic principles of GPS/INS integration and the different system-characteristics of GPS and INS are summarized.
The two different approaches for GPS/INS integration mentioned before are investigated on their accuracy performance. For the accuracy analysis the GPS/INS module was combined with a standard analogue aerial camera and flown over a well controlled photogrammetric test site. Utilizing the standard approach of indirect image orientation applying the method of aerial triangulation independent exterior orientations for the discrete camera air stations are obtained and can be used for the estimation of the accuracy potential from GPS/INS. For tile tested commercial GPS/INS module the obtained quality of directly measured orientation elements in an operational airborne environment was about ~10cm for the positioning and ~15” for the attitude. Using the GPS/INS exterior orientations for direct georeferencing without ground control an accuracy of about 8-11µm and 15-23µm in image space is obtained for horizontal and vertical components, respectively. Transferring the accuracy on medium scale photo flight from an altitude of about 2000m above ground, object points are determined with an accuracy of 10-20cm for the horizontal and 20-30cm for the vertical coordinates. This accuracy even holds for the photogrammetrically problematic case of single flight lines. The use of stronger image overlap is of positive influence on the quality of object point determination. Using the second approach of strip-wise GPS/INS evaluation in a combined AT approach similar accuracy is obtained from the same data set. Therefore, this approach offers an alternative orientation method for imaging sensors in case of non-continuously recorded INS data.
The accuracy potential of GPS/INS integration is dependent on the quality of the used sensors and the quality of the GPS update information. The influence of the remaining errors in GPS/INS positions and attitudes on the object point determination is related on the actual flying height. For large scale imagery recorded from lower altitudes positioning errors are of major influence, whereas for higher altitudes remaining attitude errors are the main part of the error budget. Additionally, the overall system quality including the GPS/INS orientation components and the imaging sensor is strongly dependent on the correct overall system calibration. Within this context system calibration is not only restricted on the correct determination of the time and spatial eccentricities between the different sensor components but the calibration of the imaging sensor itself is of major importance. Since there is no possibility of subsequent self-calibration in direct georeferencing, every difference between the assumed mathematical model and the true physical environment during data recording will cause errors in object space. Within the analyzed data set scale dependent errors in the vertical coordinate are present. which could be modelled by slightly modifying the camera focal length used for data evaluation.
The obtained empirical accuracy is of major interest for the subsequent operational use of direct georeferencing in a standard photogrammetric environment. Due to this, the GPS/INS orientation accuracy is calculated using different baseline lengths between aircraft and reference station and varying image overlap and block geometry. Additionally, the influence of interpolation errors on varying data rates used for GPS/INS trajectory computations is estimated. Against the background of direct georeferencing using GPS/INS in photogrammetric practice - without ground control in the ideal case - the overall system requirements are discussed. In the final part of this thesis the possible future use of direct GPS/INS orientation measurements in photogrammetric practice is pointed out.Numéro de notice : 27826 Affiliation des auteurs : non IGN Thématique : IMAGERIE Nature : Thèse étrangère DOI : sans En ligne : https://www.ifp.uni-stuttgart.de/dokumente/Dissertationen/Cramer_Diss.pdf Format de la ressource électronique : URL Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=56450 Réservation

Written by recognized authorities in the field, this book provides engineers, computer scientists, and others with a working familiarity with the theory and contemporary applications of Global Positioning Systems (GPS). Inertial Navigational Systems, and Kalman filters.
Throughout, the focus is on solving real-work problems, with an emphasis on the effective use of state-of-the-art integration techniques for those systems, especially the application of Kalman filtering, To that end, the authors explore the various subtleties, common failures, and inherent limitations of the theory as it applies to real-world situations, and provide numerous detailed application examples and practice problems, including GPS-aided INS, modeling of gyros and accelerometers, and WAAS and LAAS. Drawing upon their many years of experience with GPS, INS and the Kalman filter, the authors present numerous design and implementation techniques not found in other professional references, including original techniques for :
- Representing the problem in a mathematical model
- Analysing the performance of the GPS sensor as a function of model parameters
- Implementing the mechanization equations in numerically stable algorithms
- Assessing computation requirements
- Testing the validity of results
- Monitoring GPS, INS, and Kalman filter performance in operationNote de contenu : 1 INTRODUCTION
