Navigation timing equipment Combined navigation timing quote

PNT11 is a positioning, navigation, and timing (PNT) system device that meets the high reliability requirements of military applications. The system combines global satellite navigation systems (GNSS), inertial measurement units (IMU), and precision oscillators. With advanced GNSS anti-jamming and anti-spoofing algorithms, PNT11 provides reliable and accurate PNT information in environments with weakened GNSS signals, interference, or spoofing threats. Its compact 1U form factor, rugged design, and extensive time-frequency interfaces make it an ideal choice for military applications in dynamic environments.

The device features simultaneous reception of multiple GNSS signals, precise clock disciplining algorithms, and local clock combinations to provide flexible and outstanding performance in complex wartime scenarios. It supports various precision oscillators to maintain frequency and time accuracy during long GNSS signal interruptions. Built-in anti-jamming and anti-spoofing algorithm software packages are used to detect anomalous GNSS signals caused by unintentional interference or malicious attacks. If abnormal GNSS signals are detected, the system automatically switches to hold mode and issues automatic alerts. The unique embedded hardware design allows for flexible expansion of multiple signal outputs. It supports navigation, positioning information, NTP, PTP, TOD, 10MHz, 1PPS, IRIG-B, and other functions, making it suitable for applications such as blue force tracking, vehicle navigation, mobile satellite communication, cluster communication, robotics, airborne radar and electro-optical platforms, flight analysis, tactical drone navigation, and more.
