Taoglas Introduces CRPA Reference Design for Resilient GNSS Development

San Diego, CA and Munich, Germany, 10 November 2026 – Taoglas®, a trusted provider of advanced RF and antenna solutions, today announced a Controlled Reception Pattern Antenna (CRPA) reference design to help OEMs and system integrators develop more resilient GNSS systems for applications affected by interference, jamming, spoofing and multipath.

Reliable positioning, navigation and timing (PNT) has become critical to a growing range of systems, including aerospace and defense, public safety, transportation, autonomous platforms, precision agriculture, maritime, communications, infrastructure, and other mission-critical connectivity applications. However, GNSS signals are received at very low power and can be disrupted by intentional or unintentional interference. This has led to many systems being affected by intentional and unintentional jamming, leading to many issues around airports, government structures and buildings, and surveillance drones.

The Taoglas CRPA reference design provides a practical foundation for evaluating anti-jam GNSS architectures. The complete reference design combines standard Taoglas multi-band GNSS patch antennas, including the Accura GVLB258.A for L1/L5 GNSS applications, the HP2258.A for L1/L2 applications, and the HP25258.A for L1/L2/L5 applications, with TFM.110A multi-band GNSS front-end modules and supporting circuitry. The antenna options support GPS, Galileo, GLONASS and BeiDou reception across different GNSS bands.

The design is based on commercial off-the-shelf (COTS) antennas and is supplied with design files, allowing customers to select and integrate the antenna configuration that best suits their requirements. CRPA technology uses multiple antenna elements and spatial signal processing to control the reception pattern electronically, reducing sensitivity in the direction of interference sources and reflected signals.

By identifying the direction from which signals arrive, CRPA architectures can suppress unwanted in-band interference while maintaining reception of GNSS satellite signals. This capability is difficult to achieve with conventional filtering approaches alone.

The reference design forms the passive antenna and active electronics part of a complete CRPA system, helping to suppress low-elevation multipath reflections, which can degrade positioning accuracy in urban, semi-urban and vehicle-based deployments. A four-element CRPA architecture can form up to three independent nulls, depending on the overall RF design, processing platform and operating environment.

“GNSS resilience cannot be treated as an afterthought when positioning and timing are central to system availability, safety or mission success,” said Baha Badran, Global Head of Engineering at Taoglas. “The value of this reference design is that it gives engineers a practical, adaptable starting point for developing anti-jam GNSS systems for the requirements of their specific application.”

Developing an effective CRPA is a complex RF engineering challenge involving antenna element design, isolation, calibration, beamforming and overall system optimisation. The Taoglas reference design is intended to help reduce development risk and accelerate evaluation for OEMs and system integrators assessing CRPA-based GNSS solutions. It is designed as a flexible foundation rather than a fixed, one-size-fits-all solution, since the appropriate array configuration and anti-jam performance depend on the operating environment, application and threat model.

CRPA performance is influenced by factors including element isolation, antenna efficiency, phase-center stability, calibration accuracy, array geometry and integration with modern GNSS receivers and anti-jam processing platforms. The design can provide a starting point for applications including mission-critical navigation, uncrewed aerial vehicles, autonomous systems, precision agriculture, surveying and geodesy, maritime navigation, public safety, critical infrastructure, critical communications and GNSS timing systems.

Taoglas is showcasing its CRPA reference design at electronica, running from 10–13 November 2026 at Messe München, where the company is exhibiting in Hall C2, Booth 516.
