Powered by Kaelus CRPA Technology
GNSS interference and jamming are growing threats to the timing, synchronization, and positioning services that modern networks depend on.
The Kaelus Dual Band CRPA (Controlled Reception Pattern Antenna) is designed to protect GNSS reception against in-band interference by automatically forming spatial nulls toward detected jamming sources. Independent L1 and L5 processing maintains normal open-sky performance in standard operating conditions and activates interference mitigation when required.
Supporting GPS, Galileo, and BeiDou L1/L5 services, Kaelus CRPA technology helps safeguard critical timing and synchronization applications across telecommunications networks, critical infrastructure, transportation systems, utilities, public safety networks, and data infrastructure.
Purpose-built affordable technology for GNSS Jamming Mitigation
Unlike conventional GNSS antennas, Kaelus CRPA technology continuously monitors the RF environment and automatically mitigates in-band interference.
By dynamically forming spatial nulls toward detected jamming sources, the antenna removes the unwanted signals while maintaining reception of valid GNSS signals.
Independent processing of the L1 and L5 bands enables targeted interference mitigation without compromising normal antenna operation even in the presence of GNSS jamming.

Frequently Asked Questions
What is a CRPA antenna?
A Controlled Reception Pattern Antenna (CRPA) is a multi-element GNSS antenna that dynamically adjusts its reception pattern to mitigate interference and jamming.
By creating spatial nulls toward unwanted signals, a CRPA antenna helps maintain reception of desired GNSS satellite signals and protects timing and synchronization services from disruption.
How does the Kaelus CRPA antenna mitigate jamming?
The antenna automatically detects in-band interference and forms spatial nulls toward detected jamming sources. Independent L1 and L5 processing enables interference mitigation on each frequency band.
Which GNSS systems are supported?
The Kaelus CRPA antenna supports GPS, Galileo, and BeiDou L1/L5 services.
How is a CRPA antenna different from a conventional GNSS antenna?
Unlike a conventional GNSS antenna, a CRPA antenna can dynamically create spatial nulls toward interference sources. This reduces the impact of jamming while maintaining reception of valid GNSS satellite signals.
How many interference sources can the antenna mitigate?
The Kaelus CRPA antenna can generate up to three dynamic nulls per frequency band, with independent processing for L1 and L5.
Can the Kaelus CRPA antenna be integrated with existing systems?
The antenna provides an RF output and can be used in new installations or as a retrofit replacement for conventional GNSS antennas.
What applications is the CRPA antenna designed for?
Any applications that use GNSS and need to maintain reliable operation, like mobile network sites, synchronization hubs, private networks, transportation infrastructure, energy and utility facilities, public safety networks, data centers, and distributed edge sites.
Why is GNSS anti-jamming important?
Interference and jamming can affect GNSS-based timing, synchronization, positioning, and navigation. Anti-jamming technology helps improve GNSS resilience in demanding RF environments.
Why is GNSS timing important for telecommunications networks?
GNSS timing provides the synchronization required by modern mobile networks and critical infrastructure. Accurate timing supports network performance, synchronization, and operational continuity.
