The best choice in the field of PNT testing, with a complete set of real-time modeling and complex environment simulation capabilities, and a real-time performance of up to 1ms for semi physical simulation.
The NSS9000 series GNSS constellation simulator is a new generation positioning, navigation, and timing (PNT) simulation system that supports full constellation and multi frequency GNSS signal simulation. The constellation, signal, and carrier models are configured through NavSim software, which can simulate and generate high-precision and high dynamic RF signals. At the same time, it has strong user on-site upgrade and flexible configurable ability, and can flexibly configure any GNSS constellation frequency point signal output according to user requirements.
The NSS9000 adopts a high-performance large-scale real-time parallel computing software and hardware architecture, supporting up to 512 hardware channels. The channel capacity can meet the simultaneous generation of GNSS full frequency signals, with a data update rate of 1000Hz and real-time performance better than 1ms. It can fully meet the high-precision positioning, high dynamics, navigation and timing testing needs of aerospace, aviation, and other fields.
