GRIFFIN  –  GNSS RF Interference Finder

Is your mission critical GNSS RF signal environment vulnerable?

Unintended and/or malicious RFI Jamming and/or Spoofing (J&S) in the GNSS frequency band is a very real threat to the modern world’s GPS/GNSS dependant societies. When present, these RFI events may cripple regional mission critical GNSS reliant operations, potentially initiating disastrous flow-on consequences to any unsuspecting GNSS signal users.  Therefore, any technology that very rapidly detects and accurately geo-locates theses RFI sources as they occur, should be considered essential infrastructure protection for these mission critical GNSS applications.

GRIFFIN an acronym for “Gnss Rf InterFerence FINder, is a family of technology products specifically designed to quickly detect and geo-locate both regional J&S sources within the GNSS frequency bands quickly and easily.

The GRIFFIN family of products are uniquely designed to protect small areas, a few square kilometres such as regional airports, OR, out to many hundreds of square kilometres protection for larger aviation city terminal approach flight paths. GRIFFIN technology delivers pinpoint geo-location accuracies of only a few metres for the smaller coverage areas, while increasing to tens of metres for the very long distances across the larger coverage areas.

With GRIFFIN technology all significant jamming and spoofing threats are quickly detected and accurately geo-located instantly completely protecting mission critical GNSS applications..! Without GRIFFIN, your GNSS systems are vulnerable.


Technical Overview

The GRIFFIN system comprises of multiple sets of RF signal reception nodes, referred to as Sensor Nodes (SNs), typically deployed surrounding the secure facilities (e.g. airbases, airports, ports etc..) that need to be protected.  In addition, these SNs are then networked with, one or more Central Nodes (CNs)  that coordinate and control the entire GRIFFIN system.

GRIFFIN 1000

GRIFFIN 1000 is designed for providing affordable 24/7 RFI monitoring/ protection for the GNSS – L1 frequency band (30MHz bandwidth), that includes GPS-L1, GAL-E1 and BEU-B1 using our standardised Qty 8 x element antenna array configuration. The 1000 product is predominantly designed for civilian GNSS users seeking protection for aviation airport GBAS / ADSB operations, marine harbour pilot DGPS systems, and/or, critical suburban network communications / power grid timing applications.


GRIFFIN 2000 (Multi Frequency / Multi Constellation)

GRIFFIN 2000 further extends our standardised multi element antenna array monitoring across two GNSS Frequency Bands (FBs) simultaneously, each 30MHz wide covering FB1 = GPS-L1 + GAL-E1 + BEU-B1, while, FB2 covering GPS-L2, or, retuned for GPS-L5 + GAL-E5a coverage. The 2000 product is designed to provide wider GNSS spectrum protection for multi-frequency / multi-constellation users typically using GNSS for either security, and/or, precision RTK applications used for industrial machine automation projects.
