Abstract

The gravitational declination appears here as the analogue of the wellknown magnetic declination. The photographic recording theodolit in connection with a high frequency impulse transmitter allows, by a method of simultaneousness on two fieldstations, its direct and connected measurement and its elimination with regard to geodetic directions. The method has been based on linear equations, with the only request of horizontal angle measurements to a plain system of stars, abstracting from any transportable clocks. The method promises a higher accuracy and a multiple as great working velocity, comparatively to the state at present.
