Core Introduction

On November 23, 2020, the 11th China Satellite Navigation Annual Conference (CSNC2020) was held at the Chengdu Century City International Conference Center. The theme of this annual conference was "Satellite Navigation, Global New Era", and it comprehensively focused on the new opportunities, challenges, and demands faced by the Beidou system in entering the new era of global service. Hunan Weidao Information Technology Co., Ltd., as a leading domestic manufacturer of satellite navigation simulation and testing instruments, standard and customized solutions, and system integration services provider, has brought multiple new products and made a dazzling appearance at this year's Satellite Navigation Achievement Expo.

The NIF2000S is a multifunctional outdoor portable navigation suppression and deception anti-interference device, characterized by simple portability, ultra long standby, and adaptability to various extreme working environments. It can achieve simulation of GNSS full frequency band dual channel interference suppression signal, including the S-band. It supports B1/L1 frequency points for further deception, adopts a stable clock, and can be fully synchronized with satellite systems to achieve slot deception.

Nav3D simulation software for satellite occlusion and multipath effects in complex environments can interact satellite navigation signals with real 3D environments, simulate real signal paths, and control the simulator to output realistic RF signals. The signal includes the obstruction of direct satellite signals by surrounding environments such as streets, bridges, and gorges; The actual multipath signals (power attenuation, time delay, Doppler) are fully simulated by taking into account various factors such as object material, reflection coefficient, carrier motion, antenna installation position, and directional map, including one or more reflections and diffraction of satellites by ground, trees, buildings, bridges, and canyons. The relevant signals can better meet the requirements for signal occlusion and multipath effects in testing such as accuracy and anti-interference.

Core products

In addition to its debut products, the well-known NSS8900 navigation signal simulation source, RTS9000 Beidou-3 RDSS closed-loop testing system, and RPS2000 portable satellite navigation signal acquisition and playback instrument have gained the trust of users in the industry due to their excellent performance, good stability, and reliability since entering the market.
