Widely known method of combining of different information instruments of design support is formation of a common information space. However the modern nomenclature of software for the organization of a common information space not always considers specifics of a radio-electronic equipment production. In article the task on development of a mathematical model for the electronic designer document and formalization of interaction between design tools at all stages of a project cycle of a radio-electronic equipment is researched. The mathematical model of the electronic designer document with using of the subject-oriented ontology apparatus and theory of sets is offered. Dynamics of the electronic designer document life cycle is described by using of the automata theory, graphically the model of dynamics is presented in the form of the oriented graph, simulation modeling of dynamics was carried out in the numerical computing environment MATLAB with using of an extension packet Stateflow. Application area of use of the developed mathematical model is design and tests of digital receivers of navigation satellite signals. The hardware-software automated bench and software of interaction with management system the engineering data “Lotsman: PLM” within a common information space are developed for implementation of tests of the designed digital receiver.
