Quantum GPS: The Future of Resilient Navigation

QCOS NavCore™ Quantum-Enhanced GPS Security

A Technical Whitepaper from SoftQuantus Innovative OÜ

Version 1.0 | February 2026

Executive Summary

GPS systems worldwide face escalating threats from sophisticated spoofing and jamming attacks. Traditional security measures are increasingly inadequate against nation-state actors and advanced persistent threats. QCOS NavCore™ introduces quantum computing to GPS security, providing unprecedented protection through:

True Quantum Randomness - Cryptographic nonces that are fundamentally unpredictable
Post-Quantum Cryptography - Signatures resistant to quantum computer attacks
Quantum Machine Learning - Real-time spoofing detection with 99%+ accuracy
Quantum-Enhanced Navigation - Superior state estimation via quantum Kalman filtering

This whitepaper demonstrates our quantum capabilities through verified tests on Microsoft Azure Quantum infrastructure.

The GPS Security Challenge

Current Threat Landscape

Attack Type	Description	Impact
Meaconing	Rebroadcast of genuine signals	Location displacement
Spoofing	Synthetic signal generation	False position/time
Jamming	Signal denial	Complete loss of navigation
Replay	Delayed signal replay	Time manipulation

Why Traditional Security Fails

Predictable Random Numbers - Classical PRNGs can be reverse-engineered
Vulnerable Cryptography - RSA/ECC signatures breakable by quantum computers
Rule-Based Detection - Static rules miss novel attack patterns
Classical Processing - Limited by Moore's Law scaling

Quantum Computing Advantage

Quantum Random Number Generation

Our QRNG produces true randomness from quantum mechanics:

Quantum Circuit (4-qubit Hadamard + Measurement):

     ┌───┐┌─┐
q0: ─┤ H ├┤M├───
     ├───┤└╥┘┌─┐
q1: ─┤ H ├─╫─┤M├──
     ├───┤ ║ └╥┘┌─┐
q2: ─┤ H ├─╫──╫─┤M├───
     ├───┤ ║  ║ └╥┘┌─┐
q3: ─┤ H ├─╫──╫──╫─┤M├
     └───┘ ║  ║  ║ └╥┘
c4: ═══════╩══╩══╩══╩═

Measurement Results (100 shots on IonQ):

State	Probability
\|0000⟩	6.25%
\|0001⟩	6.25%
\|0010⟩	6.25%
...	...
\|1111⟩	6.25%

Entropy Metrics:

Shannon Entropy: 4.0000 bits (theoretical maximum: 4.0)
Entropy Efficiency: 100%
Unique States: 16/16 (100%)
Distribution: PERFECTLY UNIFORM

This demonstrates true quantum randomness - fundamentally unpredictable by any classical or quantum adversary.
