Challenges: Technical, Regulatory, and Cost Barriers

Jamming mitigation in Global Navigation Satellite System (GNSS) technologies faces a complex array of challenges as the threat landscape evolves rapidly in 2025 and beyond. The proliferation of low-cost jamming devices, often referred to as “personal privacy devices,” has made intentional and unintentional interference a persistent concern for critical infrastructure, transportation, and defense sectors. Technical, regulatory, and cost barriers continue to shape the pace and effectiveness of mitigation strategies.

On the technical front, GNSS receivers must contend with increasingly sophisticated jamming and spoofing techniques. Modern jammers can sweep across multiple frequencies and employ adaptive power levels, making traditional filtering and signal processing less effective. Advanced mitigation approaches, such as adaptive antenna arrays and digital beamforming, are being integrated into high-end receivers, but these solutions require significant processing power and are not yet widely available in cost-sensitive applications. Companies like Trimble Inc. and u-blox AG are actively developing multi-constellation, multi-frequency receivers with enhanced interference detection and mitigation capabilities, but the adoption of such technologies is often limited by size, weight, and power (SWaP) constraints, especially in automotive and IoT sectors.

Regulatory challenges further complicate the landscape. While the use and sale of jamming devices are illegal in many jurisdictions, enforcement remains inconsistent. The International Telecommunication Union (ITU) and national spectrum regulators are working to harmonize standards and enforcement, but the global nature of GNSS signals and the ease of acquiring jammers online undermine these efforts. In 2024, several European countries reported a surge in GNSS jamming incidents affecting aviation and maritime operations, prompting calls for stricter cross-border cooperation and real-time interference monitoring.

Cost remains a significant barrier to widespread deployment of advanced jamming mitigation. High-performance anti-jam antennas, such as controlled reception pattern antennas (CRPAs), are primarily used in military and high-value commercial applications due to their expense and integration complexity. For mass-market devices, manufacturers must balance the need for robust interference protection with the imperative to keep unit costs low.
