The local position measurement system LPM is by now one of the most advanced systems in this field. In this contribution we discuss different techniques for estimating the object position for the LPM measurement principle. These techniques include the adaptation of nonlinear least squares techniques for position estimation, a closed analytical solution based on the Bancroft algorithm known from GPS...
Precise position estimation is of great importance for many applications. Unfortunately it is still an extreme technical challenge. Due to non idealities measurements are influenced by stochastic as well as deterministic errors. In this contribution a derivation on the error propagation for additive white Gaussian noise, for inaccurate coordinates for satellites and base stations respectively as well...
The local position measurement system LPM is a novel system for fast and accurate measurements of object positions with active transponders. With an accuracy of few centimeters and measurement rates of 1000 measurements per second LPM is by now one of the most advanced systems in this field. For sensor fusion purposes each transponder is equipped with a telemetry channel. In this contribution we discuss...
In this contribution we present the reduction of an existing 3-D local position measurement system to 1-D applications. Due to this limitation the hardware complexity and therefore also the costs are reduced dramatically. Besides the discussion of the 1-D measurement principle a description of potential error sources is given. The use of the proposed 1-D position measurement system is shown on real...
