Abstract:	This paper describes the possible use and potential benefits of redundant inertial configurations for geodetic applications. As INS/GPS integration is a widely used technology for geodetic surveying and, as this surveys usually rely on a precise, reliable, and accurate INS/GPS trajectories (position, velocity and altitude), it makes sense to look at this technology in a broader perspective. In this paper a theoretical review on the potential benefits of inertial redundancy to geomatics is presented. Then, the theory of combining more than three gyros and three accelerometers is exposed and the algorithmic approach, already discussed in a previous paper ([Colomina et al., 2004]), outlined for the sake of completeness. In addition to that and in order to assess the feasibility of the theory presented, new preliminary results on a test flight with a redundant configuration (already described in [Colomina et al., 2003, Colomina et al., 2004]) are discussed.
