| Antenna technology | Controlled Reception Pattern Antenna (CRPA), multi-element array | — |
| Navigation continuity | Protects RNP, LPV and GNSS-based navigation; supports predictive navigation integrity monitoring | — |
| Integration | Compatible with existing GNSS and FMS installations; no additional pilot training required | — |
| Delivery format | Complete modification kit including parts and engineering bulletins | — |
| Initial aircraft applicability | Boeing 737NG and Boeing 747; STC development available for additional Airbus, Boeing, Embraer and other types | — |
| Announced entry into service | January 2026 (unveiled November 2025, Dubai Airshow) | — |
| Platform | — | runs on NovAtel OEM7 receiver family - OEM719, OEM729, OEM7500, OEM7600, OEM7700, OEM7720, PwrPak7, CPT7, CPT7700, SMART7, SMART2 |
| Components | — | Interference Toolkit (ITK) + Spoofing Detection Toolkit (SK), surfaced in the GRIT Monitor app of NovAtel Application Suite |
| Interference detection | — | spectral-analysis detection of in-band, near-band and strong out-of-band interference, plus statistical-analysis detection of out-of-band interference distorting the analog passband |
| Spectrum monitoring | — | RF power spectral density across all GNSS bands with interactive spectrum and waterfall views (ITSPECTRALANALYSIS / ITPSDFINAL) |
| Spoofing detection | — | single-antenna, multi-frequency multi-constellation detection metrics; at JammerTest 2023 the SK unit monitored GPS L1/L5, Galileo E1/E5a/E5b and BeiDou B1C/B2a at a 0.5 Hz detection rate with a spoofing decision every 2 seconds |
| Authentication | — | Galileo Open Service Navigation Message Authentication (OSNMA) supported as a complementary protection layer |
| Mitigation (activatable options) | — | HDR mode signal processing, notch filters for narrowband interferers, bandpass filters for band-edge interference, programmable filters (ITBANDPASSCONFIG / ITFRONTENDMODE / ITPROGFILTCONFIG) |
| Jamming characterisation | — | time-tagged snapshots of analog-to-digital samples for characterising jamming signals and developing user interference-location algorithms |
| Receiver interface | — | ITDETECTCONFIG / ITSPECTRALANALYSIS / ITWARNINGCONFIG commands and ITDETECTSTATUS / ITPSDFINAL / ITFILTTABLE logs |
| GRIT Monitor dashboard | — | Mitigation Assistant, Spectrum Viewer (spectrum + waterfall), Signal Matrix by constellation and band, Position Overview map with interference points/areas of interest and event history |
| Export status | — | non-controlled, firmware-only solution - no specific export licensing required (per NovAtel) |
| Field validation | — | jamming and spoofing detection/classification performance published from Norwegian JammerTest 2023 (Bleik, Norway) |
