Product Appearance
Product Overview
The GNSS-7000 Navigation Satellite Signal Simulator is a cost-effective, four-system satellite positioning, navigation, and timing (PNT) signal simulation system.
It supports full-constellation, full-frequency-band GNSS signal simulation. By configuring constellation, signal, and carrier models through the SimPNT software, it can generate high-precision, high-dynamic-range RF signals. It also features robust on-site upgrade capabilities and flexible configurability, allowing users to configure GNSS constellation and frequency signals for output according to their specific requirements.
It supports real-time ephemeris and external ephemeris parameter input, as well as the output of various trajectories of different durations. It meets the testing requirements for a wide range of satellite positioning and navigation receiver scenarios, including R&D and production.
Big Deal
Supports the four major navigation systems: BDS, GPS, Galileo, and GLONASS;
Supports complete L1, L5, and L2/L6 signals;
Includes the SimPNT software client for flexible configuration of parameters such as location, trajectory, and satellite settings;
Used for routine testing in GNSS R&D;
Navigation anti-jamming and anti-spoofing testing;
Sensitivity testing & CN0 testing;
Supports 24/7 long-term signal testing;
Supports remote control via LAN for flexible deployment.
Industry Applications
Widely used in all stages of the research, development, production, and testing of user devices for positioning and navigation. It can perform positioning tests, velocity tests, delay tests, and related accuracy tests.
It is suitable for the research, development, and testing of products that rely on satellite navigation and positioning functions, such as autonomous driving systems, navigation and positioning devices, and geofencing devices. It can significantly improve efficiency, eliminate the need for frequent on-site field testing, and greatly accelerate the speed of product development, testing, and deployment.
