NavCore Changelog

All notable changes to NavCore are documented here.

[3.2.0] - 2026-02-06​

🎯 Quantum GPS Release​

Major release introducing full GPS resilience with quantum-secured positioning.

Added​

  • Quantum GPS Module: Full positioning, navigation, timing (PNT) system
  • QRNG Holdover: <50ns/hour drift using quantum entropy
  • Spoofing Detection: Real-time detection in <50ms
  • Position Evidence Bundles: Cryptographic proof of position
  • Timing Bounds API: Guaranteed precision limits
  • Multi-constellation support: GPS, Galileo, GLONASS, BeiDou

Performance​

  • Position accuracy: <1m CEP95
  • Timing accuracy: <100ns
  • Holdover accuracy: <50ns/hour (20x better than industry)
  • API response time: <10ms

Migration Guides​

From 3.1.x to 3.2.x​

The 3.2 release is backward compatible. New features are additive.

# Old (still works)
from qcos.navcore import get_position
position = get_position()

# New (recommended)
from qcos.navcore import QuantumGPS
gps = QuantumGPS()
position = gps.get_position(
    authenticate=True,
    spoofing_check=True
)

From 3.0.x to 3.1.x​

Update import paths:

# Old
from qcos.navigation import NavCore

# New
from qcos.navcore import QuantumGPS
