NavCore — Quantum Navigation

NavCore is QCOS’s quantum-enhanced navigation and positioning module. It provides post-quantum secure GNSS authentication (OSNMA), quantum-assisted inertial navigation for GNSS-denied environments, NIS2-compliant positioning integrity monitoring, and RAIM (Receiver Autonomous Integrity Monitoring) analytics.

Key Capabilities

Feature	Description
OSNMA verification	Open Service Navigation Message Authentication — validate that GNSS signals have not been spoofed
QRNG-seeded timing	Use quantum random bits for timing unpredictability in secure navigation protocols
Quantum INS	Quantum-assisted inertial navigation system for underground / maritime / space use
RAIM analytics	Real-time satellite geometry analysis and fault detection
NIS2 positioning	Generate NIS2 Article 21-compliant positioning integrity certificates
Anti-spoofing	Detect GNSS spoofing and jamming using statistical quantum signatures

GNSS Signal Authentication (OSNMA)

POST /api/v1/navcore/compliance/osnma/verify

Verify that a received Galileo navigation message is authentic using OSNMA cryptographic authentication.

{
  "svid": 12,
  "message_type": "inav",
  "subframe_data": "base64-encoded-subframe...",
  "osnma_data": "base64-encoded-osnma-fields...",
  "tow": 345612,
  "wn": 1289
}

Check the live authentication picture with GET /api/v1/navcore/compliance/osnma/status and per-satellite state with GET /api/v1/navcore/compliance/osnma/satellites.

For environments without GNSS (tunnels, deep-sea, space), NavCore maintains a quantum-assisted Kalman filter that fuses inertial and quantum-sensor measurements:

POST /api/v1/navcore/quantum/kalman/predict   # propagate the state forward
POST /api/v1/navcore/quantum/kalman/update    # fuse a new measurement
GET  /api/v1/navcore/quantum/kalman/state     # read the current state estimate
POST /api/v1/navcore/quantum/kalman/reset     # reinitialise the filter

Configure the quantum sensing pipeline with POST /api/v1/navcore/quantum/configure, and characterise sensor noise with POST /api/v1/navcore/quantum/noise/characterize.

RAIM Analysis

POST /api/v1/navcore/raim/process

{
  "timestamp": "2025-01-15T12:00:00Z",
  "gnss_measurements": [
    {"prn": "G01", "el_deg": 45, "az_deg": 90, "snr_db": 42},
    {"prn": "G03", "el_deg": 32, "az_deg": 210, "snr_db": 38}
  ],
  "alert_limits": {"horizontal_m": 40}
}

Read the current protection levels with GET /api/v1/navcore/raim/protection, detected threats with GET /api/v1/navcore/raim/threats, and exclude a faulty satellite with POST /api/v1/navcore/raim/exclude.

NIS2 Compliance Reporting

GET /api/v1/navcore/compliance/nis2/status
GET /api/v1/navcore/compliance/summary
GET /api/v1/navcore/standards/conformance-report

curl -H "Authorization: Bearer $QCOS_API_KEY" \
  "https://api.softquantus.com/api/v1/navcore/standards/conformance-report"

Returns positioning-integrity conformance reporting aligned to NIS2 Article 21. Report NIS2 incidents with POST /api/v1/navcore/compliance/nis2/incident and review gaps with GET /api/v1/navcore/compliance/nis2/gaps.

Anti-Spoofing Detection

POST /api/v1/spoofing/detect

Submit GNSS observables and receive a statistical spoofing assessment. Live threat state is also surfaced at GET /api/v1/navcore/raim/threats.
