Specs
Technical specifications.
| Spec | NovAtel GRIT - GNSS Resilience and Integrity Technology | BroadShield GNSS Jamming & Spoofing Detection (SecureSync Interference Detection Suite) |
|---|---|---|
| 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 | GNSS simulator signatures, GPS data anomalies, data inconsistencies, position jumps, time jumps |
| 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) | — |
| Jamming detection | — | CW tone, swept CW, pulsed CW, AWGN, BPSK and more |
| Monitored signals | — | GPS L1 (1575.42 MHz) and L2 (1227.6 MHz) |
| Hardware requirements | — | Works with standard commercial GPS/GNSS receivers — no additional hardware required |
| SecureSync integration (SS-OPT-BSH) | — | event logging, alarms, SNMP/email notification, automatic disabling of GNSS sync with switch to backup reference or oscillator holdover |
| Embeddable software library | — | convertible to most major programming languages, runs on nearly any operating system |
| Integration requirements | — | GPS receiver providing raw GPS NAV data + processing unit + Safran integration support |
| Threat library updates | — | Detection algorithms regularly updated against new and emerging threats; field-proven 10+ years |
| Ordering / variants | — | SS-OPT-BSH — Interference Detection Suite option for SecureSync time servers (software option, also available as field upgrade); BroadShield SDK — embeddable software library for OEM hardware platforms via Safran Federal Systems; complemented by BroadSense interference detection sensors. |
