In the article below, Tualcom outlines the benefits of Controlled Reception Pattern Antennas (CRPA) for countering GPS/GNSS interference, detailing the technology behind CRPA Antennas, their suitability for defense and aviation applications, and how they are able to boost connection reliability. 

In today’s world where GPS/GNSS technology is used in everything from navigation systems to fitness trackers, having a reliable and accurate GPS/GNSS signal is crucial.

Benefits of CRPA Antennas for Reliable Signal ProcessingHowever, intentional and unintentional interference is a big threat to sustaining GPS/GNSS’s availability in certain environments.

This is where CRPA antennas come in. In this article, we will discuss what CRPA antennas are and how they can boost the reliability of GPS/GNSS signals.

What are CRPA Antennas?

CRPA stands for Controlled Reception Pattern Antennas. These antennas are designed to receive and process GPS/GNSS signals in a way that minimizes interference and maximizes accuracy. They use multiple antenna elements and advanced signal processing techniques to achieve this.

CRPA Antenna Design

The design and control of CRPA antennas is crucial in their ability to boost reliability. These antennas typically consist of multiple antenna elements that are electronically controlled to create a controlled reception pattern.

This pattern allows the antenna to receive and process signals from multiple satellites simultaneously while mitigating the effects of interference.

Advanced Signal Processing
In addition to the antenna design, CRPA antennas also use advanced signal processing techniques to further improve reliability.

These techniques include adaptive beamforming, which allows the antenna to focus on specific directions and reject others, and null steering, which helps to cancel out interference from unwanted directions.

Benefits of CRPA Antennas

CRPA antennas offer several benefits that make them a popular choice for applications where sustained GPS/GNSS signals are crucial.

Improved Availability
By using multiple antenna elements and advanced signal processing techniques, CRPA antennas can significantly improve the availability of GPS/GNSS signals. This is especially important in environments where GPS/GNSS signals may be jammed or spoofed.

CRPA antennas can be used in a variety of applications, from military and defense to commercial and consumer use. They are also compatible with different GPS/GNSS bands, making them a versatile choice.

Applications of CRPA Antennas

CRPA antennas have a wide range of applications, including:

  • Military and defense: CRPA antennas are commonly used in military and defense applications, where reliable GPS/GNSS signals are crucial for navigation, communication, and targeting.
  • Aviation: These antennas are used in aircraft for navigation and communication purposes.
  • Automotive: CRPA antennas are becoming increasingly popular in the automotive industry, where they are used for navigation and driver assistance systems.
  • Agriculture: In precision agriculture, CRPA antennas are used to improve the accuracy of GPS/GNSS-guided equipment.
  • Personal devices: CRPA antennas are also used in personal devices such as fitness trackers and smartwatches to improve the accuracy of GPS/GNSS tracking.


CRPA antennas are a crucial component in improving the availability of GPS/GNSS signals. With their advanced design and signal processing techniques, they offer improved accuracy and reliability in a variety of applications. As technology continues to advance, CRPA antennas will play an increasingly important role in ensuring the availability and reliability of GPS/GNSS signals.
