More Information
Summary:The invention relates to a method and an apparatus for taking readings of gravity by an airborne vehicle, in which the airborne vehicle is stabilised as far as speed, trajectory direction and altitude are concerned, and in which is provided a gravity measuring device which possesses appropriate sensitivity and which produces signals which are recorded at a high sampling frequency on a magnetic tape, the position of the airborne vehicle being calculated by using a multiple-range navigation system which is geodisically localised. L'INVENTION CONCERNE UN PROCEDE ET UN APPAREIL POUR L'EXECUTION DE RELEVES DE GRAVITE PAR VEHICULE AEROPORTE, OU LE VEHICULE AEROPORTE EST STABILISE EN CE QUI CONCERNE LA VITESSE, LA DIRECTION DE TRAJECTOIRE ET L'ALTITUDE ET OU IL EST PREVU UN DISPOSITIF DE MESURE DE GRAVITE QUI POSSEDE UNE SENSIBILITE APPROPRIEE ET QUI PRODUIT DES SIGNAUX QUI SONT ENREGISTRES A UNE GRANDE FREQUENCE D'ECHANTILLONNAGE SUR UNE BANDE MAGNETIQUE, LA POSITION DU VEHICULE AEROPORTE ETANT CALCULEE EN UTILISANT UN SYSTEME DE NAVIGATION A GAMMES MULTIPLES QUI EST LOCALISE GEODESIQUEMENT.
