Abstract

Предлагается летательный аппарат (10), который выполнен с возможностью проведения авиационных гравиметрических разведок, содержащий гравиметр (14), приемник (18) глобальной навигационной спутниковой системы (ГНСС), поддерживающий сигнальную связь с гравиметром (14), а также систему (20) доплеровского лидара, поддерживающую сигнальную связь с гравиметром (14). Система (20) лидара выполнена с возможностью определения вертикальной скорости летательного аппарата (10) в предварительно определенное время, при этом сигнал времени от ГНСС-приемника (18) используется для оперативной синхронизации результатов измерений как гравиметра (14), так и системы (20) лидара. Таким образом, результат измерения гравитационного ускорения гравиметра (14) может быть отделен от кинематического ускорения, выводимого из результата синхронного измерения лидара.
