Abstract

With the rapid development of UAV technology, UAV as a measurement carrier has been widely used. This paper introduces the basic principle of Strapdown airborne gravimetry. The vertical gravity disturbance is compensated by the error parameter estimation method. The experimental results show that UAV has the characteristics of no airport support and short preparation time before measurement. The internal coincidence accuracy is 0.50mGal under the condition of undulating flight, 1.26mGal under the condition of large maneuver, and 0.47mGal and 0.84mGal respectively after compensation. The internal coincidence accuracy shows that the gravity measurement accuracy is high and the instrument stability is good under the condition of undulating flight, which also shows the feasibility of UAV in airborne gravity measurement. The compensation results show that the error parameter estimation method is suitable for UAV airborne gravity measurement in undulating flight conditions.
