Recent Progress in and Utilization of Astrogeodetic-Inertial and Astrogeodetic-Gradiometric Gravity Vector Determination (Zu juengstem fortschritt in der und anwendung von astrogeodaetisch-inertialer und astrogeodaetisch-gradiometrischer schwerevektorbestimmung) (Progres recents et utilisation du calcul du vecteur pesanteur par astrogeodesie inertielle et astrogeodesie gradiometrique).

摘要

Following an introductory status review, the paper presents a new astrogeodetic-gradiometric-inertial method for vertical deflection determination under consideration of horizontal channel interactions and suitable for the utilization of single of multiple track data in conjunction with supporting astrogeodetic deflections. It then discusses the problem of optimal deflection area adjustments under consideration of other work. Subsequently, accuracy aspects of astrogeodetic-gradiometric gravity vector determination based on the Bell gravity gradiometer, the simultaneous utilization of gradiometric and inertial data in terrestrial surveys, and potential applications are addressed.
