[Termes IGN] orbitographieRésumé : (auteur) DORIS is a French precise orbit determination system. However, in the past four years, through the creation of the International DORIS Service, a larger international cooperation was involved. Furthermore, the precision of its scientific applications (geodesy, geophysics) gradually improved and expanded to new fields (atmospheric sciences), leading, for example, to the publication of a special issue of the Journal of Geodesy. The goal of this manuscript is to present and explain these changes and to put them in perspective with current results obtained with other space geodetic techniques, such as GPS or Satellite Laser Ranging.

[Termes IGN] stéréoscopieRésumé : (Auteur) We formulate and present a new geopositioning method for SPOT-5 High-Resolution Geometric (HRG) stereo images, named the line-of-sight (LOS) vector adjustment model. It is applicable to satellites that move along a well-defined close-to-circular elliptical orbit with a predicted orbit close to true. SPOT-5 satisfies these requirements because it has the improved capability of providing accurate satellite attitude and a look angle for each detector. The method’s core idea is that only the LOS vector was adjusted when correcting the geometric distortion of SPOT-5 imagery. One advantage of this method is that it achieves high geopositioning accuracy with a limited number of ground control points (GCPs). Although a minimum of three GCPs is needed for processing, a test result satisfied the accuracy requirement within one pixel of a SPOT-5 panchromatic image even with only three GCPs. The performance in terms of root mean square error (RMSE) improved as the number of GCPs increased. Five GCPs were found to be the optimal number in the practical application of the LOS vector adjustment model. Using five GCPs, the RMSEs were 0.48 m and 0.64 m in planimetry and height, respectively. The test results indicate that the proposed method is superior to the bundle adjustment method for the geopositioning of SPOT-5 HRG stereo images.

[Termes IGN] orbitographieRésumé : (auteur) Three currently operational radar altimeter satellites are equipped with the Doppler orbitography and radiopositioning integrated by satellite (DORIS) tracking system for precise orbit determination and two more are already foreseen. Any systematic errors in their computed orbits could possibly adversely affect scientific products used in climate change studies, such as sea level and ice sheet heights. DORIS residuals, which can be interpreted as a measure of orbit determination performance, often show systematic errors. We have therefore analyzed long time series of DORIS range-rate residuals in order to investigate possible systematic errors common to all DORIS analysis strategies and software packages, either on a satellite or on a station basis. In particular, the investigation has focused on global DORIS data of six satellites (TOPEX, Jason, Envisat and SPOT-2, -4 and -5) and station-specific data for Fairbanks, Easter Island and Syowa Base. Large measurement errors when crossing the South Atlantic Anomaly are easily detected in the DORIS residuals of Jason, while Envisat residuals show the most prominent evidence of multipath interference and the effect of a flight software update. Particularly, large errors were also found in low-elevation data.
