Full-band VOR SDR
Software-defined reception across the entire VOR band. Independent of GPS availability and designed to maintain bearing information when satellite signals are jammed, spoofed, or unavailable.
Experimental Aircraft Avionics
Navigation that keeps working when GPS doesn’t.
Voracious Avionics is building a high-integrity GA navigation system that combines dual-frequency GPS with full-band VOR SDR, inertial sensing, and air-data — designed from the ground up for real-world resilience.
Core capabilities
A tightly integrated sensor and RF suite focused on continuity of navigation under degraded or contested conditions.
L1 + L5 dual-frequency GPS
Multi-constellation GNSS with both L1 and L5 signals for improved accuracy, integrity monitoring, and better resistance to interference compared with single-frequency receivers.
Integrated IMU & air data
On-board inertial measurement and pitot-static sensing provide attitude, heading reference, and airspeed data that can be fused with RF navigation sources for continuous state estimation.
FPGA-centric architecture
High-performance processing on modern FPGA silicon enables real-time SDR, sensor fusion, and deterministic timing — without the opacity of closed commercial black boxes.
Modern aircraft interfaces
Ethernet, ARINC 429, and UART interfaces with clean electrical design for straightforward integration into experimental aircraft systems and glass cockpits.
Built for experimental GA
Sized and powered for the realities of experimental aircraft: owner-maintained systems, limited panel real estate, and the need for transparent, inspectable behavior.
Technical approach
Hardware and software choices driven by performance, observability, and long-term maintainability rather than marketing checkboxes.
-
01
Wideband VOR reception SDR architecture covering the full VOR frequency range so the system is not limited to a single tuned channel or proprietary demodulator.
-
02
Dual-frequency GNSS front-end L1 and L5 capable receivers (u-blox F9 class) for better multipath rejection and ionospheric error mitigation.
-
03
Sensor fusion foundation IMU + pitot-static data available for dead-reckoning and integrity cross-checks when RF sources disagree or degrade.
-
04
Deterministic processing FPGA-based signal processing and control paths to keep latency and timing behavior predictable under load.
-
05
Aircraft-native interfaces ARINC 429 and UART alongside Ethernet so the unit can talk directly to existing EFIS, autopilots, and experimental avionics without awkward adapters.
-
06
Owner-accessible design Intended for the experimental community that builds, maintains, and flies its own aircraft — not a sealed black box.
