description: The given work is devoted to the creation of a portable global navigation satellite systems (GNSS) signal simulator. GNSS signal simulators are used for organizing local navigation systems (LNS), as well as for testing navigation equipment. Existing solutions do not provide a portable device, however, tasks arise that require small-sized simulators, for example, a quick reorganization of an LNS or testing navigation equipment when a simulator is installed on an unmanned aerial vehicle with a small carrying capacity. Therefore, the goal of the work is to create a portable simulator of the signals of global navigation satellite systems.
A model for simulating GNSS signals in Matlab was created, and a simu-lator was implemented on a chip Zynq 7020. A measurement error of an object coordinates is investigated based on signals generated by a simulation model or simulator using a GNSS-SDR software-defined receiver.
The error of an object coordinates was measured in static and dynamic modes based on the simulation, and as a result, it was found that the refresh rate of the signal parameters should be 10 Hz and higher for simulation of static and moving objects (with velocities of the order of 10 m/s - 50 m/s). The cre-ated simulator on Zynq provides accuracy in static mode within 1 m, and in dynamic mode within 3 m (refresh rate is 10 Hz). Its processor part has a typical power consumption of 1 W and a chip size of 17x17 mm, these values can satisfy the given portability restrictions. The results of the work could be required in developing portable simulators and pseudolites. As a result of the work, the goal was achieved, and all tasks were completed.
