Multi-Constellation GNSS Antennas With Anti-Jamming Technology

Pasternack is expanding its GNSS portfolio with a new generation of ruggedized (MIL-STD-810) antennas engineered for positioning, navigation, and timing applications operating in increasingly congested RF environments.

These upcoming single- and multi-band solutions support GPS, Galileo, GLONASS, BeiDou, QZSS, NavIC, and regional augmentation systems across L1/E1/B1, L2, and L5/E5 frequency bands while incorporating advanced interference mitigation technologies designed to improve GNSS performance in the presence of jamming and adjacent-band RF activity.

Key capabilities include:

• Low-elevation signal suppression technology provides 20 dB attenuation for signals arriving near the horizon, helping reduce susceptibility to many ground-based jamming sources.
• Enhanced out-of-band rejection that mitigates interference from adjacent wireless, satellite communications, and terrestrial transmission services that can desensitize conventional GNSS receivers.
• High-linearity front-end architecture designed to reduce amplifier saturation and maintain receiver performance in challenging RF environments.
• Multi-frequency operation supporting modern GNSS constellations and correction services for improved positioning accuracy and signal availability.
• Excellent axial ratio performance and strong multipath rejection characteristics.
• High-gain, low-noise amplification with strong signal-to-noise performance maintaining precise timing and positioning capability.

Applications include:

• Autonomous and unmanned platforms
• Mission-critical positioning and navigation
• Precision timing and synchronization
• Public safety and law enforcement systems
• Transportation and fleet management
• Critical infrastructure monitoring
• Survey, mapping, and geospatial systems

Designed for demanding outdoor deployments, these antennas feature weather-resistant construction, broad operating temperature ranges, and support for installation in fixed, mobile, and infrastructure-based GNSS systems.
