Anti-Spoofing GNSS Signal Monitoring System

Time Synchronization Protection Equipment

• Automatically switch between synchronization hold mode and denial sustain mode based on the status of input signals.

• Real-time monitoring of satellite navigation signals at the installation location of the timing equipment, with the capability to detect interference, trigger alarms when interference is present, and promptly alarms once the interference ceases.

• Automatically isolate non-secure GPS L1 and BDS B1 signals to ensure the normal operation of the timing equipment. Features static and dynamic user trajectory generation.

• Equipped with data reporting functionality, log storage, and the ability to record alarm statuses, disciplining statuses, operational statuses, and the health of input signals.

• Monitor output signal status and log alerts for abnormal output signals. Equipment operation inspection requires monitoring the health of input signals and logging accordingly.

• Capable of remotely receiving command and control instructions to configure output signals and report operational status in real-time.

• Resistant to meaconing and spoofing signals, maintaining output of signals that meet time synchronization precision requirements.

• Under full-band jamming interference conditions, sustain signal output to meet holdover accuracy requirements.

Improve the security, stability and anti-attack capability of the timing system. In the case of full frequency suppression interference, the signal output can be maintained to meet the requirements of punctuality and accuracy, and it is compatible with the time timing equipment of the existing power system. It can be installed between the time timing equipment and the navigation satellite signal receiving antenna without replacing the original time equipment, real-time monitoring of the health and safety status of the received navigation satellite signals, and identification and isolation of interference signals and deception signals. Improve the security, stability and anti-attack capability of the timing system.

Automatic isolation of unsafe GPS and BDS signals to ensure the normal operation of the timing equipment, the product uses a standard 1U chassis, easy to mount.

Automatic switching between synchronous hold mode and deny hold mode according to the state of the input signal.

Real-time monitoring of timing equipment installation location satellite navigation signal, determine whether there is interference, and alarm when there is interference; When the interference disappears, clear the alarm in time.

Automatically isolate unsafe GPS L1 and BDS B1 signals to ensure proper operation of the timing device. It has static and dynamic user trajectory generation function.

It has the function of data reporting and log storage, and can record the alarm status, tame status, running status, and input signal health status.

Monitor the output signal status, log alarm when the output signal is abnormal. Monitor the health status of input signals and record them in logs.

It can receive command and dispatch commands remotely, configure output signals, and report working status in real time.

It is not affected by the forwarded and generated spoofing signals, and continuously outputs the signals that meet the requirements of time synchronization accuracy.

Under the condition of full frequency suppression interference, the signal output is maintained to meet the requirements of punctuality and accuracy.
