Pihulka™ 60D
GNSS Anti-Jamming CRPA Antenna
Active GNSS protection against electronic warfare jamming. Designed for equipment that must operate at all times, even in heavy interference environments.
GNSS signal protection when conventional antennas fail
Problem: Modern electronic warfare (EW) systems can easily jam conventional GNSS receivers. Drones lose navigation, anti-theft trackers stop working, and precision agriculture equipment becomes unreliable.
Solution: Pihulka™ 60D is a Ukrainian adaptive 4-element CRPA antenna with digital interference suppression. It automatically forms spatial nulls toward jamming sources while preserving clean satellite signals.
Key Features of Pihulka™ 60D
- Adaptive spatial filtering — dynamically creates nulls in the direction of jamming sources
- High interference suppression — up to 50+ dB (5 MHz), over 30 dB (20 MHz)
- Multipath mitigation — improved positioning accuracy in complex environments
- 4-element antenna array with digital signal processing
- Supported signals: GPS L1, SBAS L1, Galileo E1, QZSS L1
- Interfaces: Ethernet + UART for easy system integration
Development Status
A working prototype of the Pihulka™ 60D already demonstrates effective interference suppression in real-world tests. The system is currently undergoing extended field trials and preparation for small-scale production.
