By using data collected from multiple antennas on board a single flight vehicle, and by employing differential corrections supplied by a fixed ground receiver, this numerical method can produce Earth Centered Earth Fixed (ECEF) coordinates for a specified point on a vehicle, as well as the Euler angles (pitch, roll, yaw) expressing the angular orientation of the vehicle at that point. This analysis has applications for any mobile platform where position and orientation information is desired. The particular application we tested is in regards to aerial photogrammetry.

Local geoid determination using global positioning systems / K. Jeyapalan in Surveying and land information science, vol 64 n° 1 (01/03/2004)

Public [article]  inSurveying and land information science > vol 64 n° 1 (01/03/2004) . - pp 65 - 75 Titre : Local geoid determination using global positioning systems Type de document : Article/Communication Auteurs : K. Jeyapalan, Auteur Année de publication : 2004 Article en page(s) : pp 65 - 75 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géodésie physique [Termes IGN] altitude orthométrique [Termes IGN] contrôle altimétrique [Termes IGN] géoïde local [Termes IGN] Iowa (Etats-Unis) [Termes IGN] positionnement cinématique en temps réel [Termes IGN] positionnement par GPS [Termes IGN] prédiction Résumé : (Auteur) It is well established that elevations determined by global position systems are above reference ellipsoid heights and should be corrected for geoid undulation to determine the orthometric height or mean sea-level elevation. The paper describes research performed at Iowa State University in cooperation with Iowa Department of Transportation to determine the local geoid, N1 with + 2 cm accuracv for a countywide area, study its variation with time, and develop a method to predict the future local geoid with + 2 cm accuracy. This paper describes the data collection method, provides the results of three observations at six-month intervals for studying the variation of N with time; explains a method developed for predicting N1 and determining agreement with a fourth observation; and describes a procedure for establishing elevation control by global positioning systems for leveling and for establishing control in a real-time kinematic global positioning systems project.
