YH836 8-Channel CRPA for High-Threat NAVWAR Environments

In an era of escalating electronic threats and coordinated multi-source attacks, standard GNSS protection is no longer sufficient. The YH836 is an unmatched defensive fortress for your navigation system, engineered to provide dominant Assured PNT performance in the most hostile and saturated NAVWAR environments.

Product Overview

The YH836 is an elite, 8-channel Controlled Reception Pattern Antenna (CRPA) system designed for platforms that require the absolute highest level of navigational resilience. Its 8-element antenna array enables the advanced spatial filtering and nullification of up to seven independent jamming sources simultaneously. By processing signals from BeiDou B1, GPS L1, and GALILEO E1, and offering SWaP-optimized configurations (including a lightweight magnesium alloy option), the YH836 ensures that high-value assets maintain precise positioning and timing to achieve mission dominance under any conditions.

Key Features & Benefits

• Overwhelming Jammer Suppression: With the ability to identify, track, and nullify up to 7 simultaneous jammers, the YH836 provides an unprecedented level of protection against sophisticated, coordinated electronic attacks.
• Superior Jamming-to-Signal (J/S) Ratio (≥105dB): The system's advanced algorithms carve deep, precise nulls in the direction of interference, maintaining a lock on satellite signals even when faced with powerful jamming.
• SWaP-Optimized for Mission Versatility: Available in a rugged aluminum alloy (≤980g) or an ultra-lightweight magnesium alloy (≤750g), providing critical weight savings for UAVs and other SWaP-constrained platforms.
• Multi-Constellation Signal Processing: Ensures robust satellite tracking by utilizing signals from BDS, GPS, and Galileo, maximizing availability for a continuous and reliable PNT solution.
• Engineered for the Edge: Built to withstand the rigors of modern warfare with a wide -40°C to +75°C operating temperature range and integrated anti-spoofing capabilities.

Primary Applications

• Strategic & High-Value Unmanned Systems (HALE/MALE UAVs): The ultimate PNT protection for critical ISR, strike, and communications relay platforms operating in highly contested airspace.
• Naval Surface Combatants & USVs: Ensures the navigational integrity of destroyers, frigates, and autonomous vessels during complex maritime operations.
• Armored Brigade Combat Teams (BCTs): Provides mission-critical navigation for command vehicles, main battle tanks, and artillery systems in a dense EW environment.
• Airborne C4ISR & Electronic Attack Platforms: Delivers a trusted PNT source for aircraft responsible for command, control, and electronic warfare.

Frequently Asked Questions (FAQ)

What is the key advantage of an 8-channel CRPA like the YH836?

The primary advantage is the ability to nullify more simultaneous threats. With 8 antenna elements, the YH836 can defeat up to 7 jammers, whereas 4-channel systems can only handle 3. This makes it the superior solution for high-value assets that are likely to face complex, multi-source electronic attacks.

Which version should I choose: aluminum or magnesium alloy?

The magnesium alloy version offers a significant weight reduction of nearly 25%, making it the ideal choice for SWaP-sensitive platforms like large UAVs where reducing weight directly translates to increased flight endurance and payload capacity. The aluminum version provides maximum durability for ground vehicles and naval applications.

Can this system be customized to include GLONASS or other bands?

Yes. While the standard configuration supports BDS B1, GPS L1, and Galileo E1, our engineering team can customize the YH836 to process signals from other constellations like GLONASS or different frequency bands (e.g., L2/L5) to meet specific mission requirements.
