1. Product Overview
This navigation signal simulation module adopts GNSS signal
simulation technology, covering BDS, GPS, GLONASS and Galileo. It
generates real-time satellite signals identical to genuine ones to
mislead drone positioning receivers.
It enables multiple low-altitude UAV safety management: heading
guidance, diversion, smooth forced landing and controlled crash.
With radar cooperation, it can guide drones to designated landing
spots.
Customizable in functions and performance, it serves petroleum,
power, public security and safety protection industry.
2. Main Functions
- Realize full-area, all-weather, long-distance autonomousfull-area
all-weather long-distance low-altitude UAV safety management.
- Spoof navigation-dependent UAVs to achieve diversion, heading
guidance, no-fly zone control, smooth forced landing and rapid
crash; precise fixed-point landing guidance with radar assistance.
- Customize flight trajectory of target UAVs, freely combine uniform
speed, acceleration and circular motion control modes.
- Manual & automatic transmit power adjustment modes for flexible
adaptation to different control distances.
- Automatically identify spoofing radius, dynamically optimize
spoofing performance and suppress co-frequency interference.
- Manual & automatic switching for spoofing location parameters and
flight guidance modes.
- Automatic start/stop of RF power amplifier; RF output can be
switched via external terminal level signal.
