Workspace measurement and positioning system works at multi-station in a synergistic effect and how to deploy the stations has a significant impact on the measurement range, accuracy, and the use-cost. This paper explores the effect of the geometry of station distribution on position errors based on the relation between the wMPS network deployment and position errors. Firstly, a positioning error model was established, the station one-way communication constraints were analyzed, and the improvement of increasing the number of stations on measurement accuracy was analyzed. Then, typical deployments of two to four stations were designed and the error distribution characteristics were studied. Finally, the error characteristics of typical deployments were verified based on the latest prototype in a lab. Experiment results show that O_4 typical deployment has the highest accuracy, the measuring accuracy from the L_3 typical deployment is higher by 40% than that of the I_2 deployment. Moreover, O_4 typical deployment has 20% improvement on measuring accuracy than that of the L_3 typical deployment. The research work provides an effective theoretical support for global measurement network optimization.
