YH168 Multi-Constellation CRPA Anti-Jamming Antenna System for Assured PNT

In the era of advanced electronic and navigational warfare (NAVWAR), mission failure is not an option. The YH168 CRPA system provides an impenetrable shield for your GNSS signals, delivering continuous and trustworthy navigation data to dominate in the most severe GPS-denied and contested environments.

Product Overview

The YH168 is an elite, 4-channel Controlled Reception Pattern Antenna (CRPA) system engineered for platforms that demand the highest level of Assured Positioning, Navigation, and Timing (PNT). By simultaneously processing signals from four major constellations—GPS, GLONASS, Galileo, and BeiDou—it offers unparalleled redundancy and resilience. The system's advanced algorithms and robust hardware are designed to receive, filter, and perform deep nulling of up to three simultaneous interference sources, ensuring high-precision PNT data is maintained during sophisticated electronic attacks.

Key Features & Benefits

• Unrivaled Constellation Redundancy: True quad-band capability (GPS L1, GLONASS G1, Galileo E1, BDS B1) ensures maximum satellite visibility and robust positioning accuracy in any operational theater worldwide.
• Dominant Jamming Mitigation (≥110dB J/S Ratio): Industry-leading Jammer-to-Signal (J/S) suppression nullifies powerful broadband, sweep, and pulse jammers, guaranteeing the integrity of your navigation solution.
• Advanced Multi-Threat Defense: Employs sophisticated spatial filtering to simultaneously identify and neutralize up to 3 interference sources, providing comprehensive protection against coordinated electronic warfare tactics.
• SWaP-Optimized Design: Offered in two distinct configurations—a lightweight magnesium alloy (≤700g) for UAVs and a rugged aluminum alloy (≤900g) for ground vehicles—to meet stringent Size, Weight, and Power (SWaP) constraints.
• Built for the Modern Battlefield: With a wide operational temperature range (-40°C to +75°C) and built-in anti-spoofing capabilities, the YH168 is mission-ready for the most demanding environments.

Primary Applications

• Strategic & Tactical Unmanned Platforms (UAV/UGV): The definitive anti-jamming solution for ISR, combat, and logistics drones and ground robots operating in GPS-denied zones.
• Naval Surface Warfare & USVs: Delivers robust, multi-constellation PNT for warships, patrol craft, and unmanned surface vessels, enhancing situational awareness and weapon systems accuracy.
• Armored Vehicles & Manned Aircraft: Provides a critical layer of navigational resilience for ground combat vehicles, helicopters, and fixed-wing aircraft in high-threat EW scenarios.
• Critical Infrastructure Protection: Safeguards precise timing and synchronization for mobile command posts, communication nodes, and other vital assets.

Frequently Asked Questions (FAQ)

What is the advantage of a multi-constellation CRPA system?

A multi-constellation CRPA like the YH168 tracks more satellites simultaneously (GPS, GLONASS, etc.). This creates a more robust and accurate position solution that is significantly harder to disrupt than a GPS-only system, providing a critical advantage in contested environments.

How does the magnesium alloy option impact performance?

The magnesium alloy enclosure reduces total system weight by over 20% without compromising performance or durability. This is a critical advantage for SWaP-sensitive platforms like UAVs, as it allows for longer flight endurance or increased payload capacity.

Is this system ITAR-free?

Yes, the YH168 is a commercial, non-ITAR controlled item, which simplifies the procurement and deployment process for our global partners. Please contact us for specific exportability details regarding your region.
