NORTH STAR
Navigate Without GPS
Multi-modal sensor fusion combining celestial observation, magnetic anomaly detection, inertial measurement, and terrain correlation delivers 10-meter accuracy with 99% availability, even when GPS is jammed, spoofed, or denied.
GPS Is Civilization's Largest Single Point of Failure
A $30 jammer can deny GPS across a 50km radius. Nation-states routinely jam theater-level areas.
The GPS Vulnerability Crisis
GPS signals arrive at Earth's surface at -160 dBW, weaker than cosmic microwave background radiation. Russia routinely jams GPS across the Eastern Mediterranean, Black Sea, and Baltic. Sophisticated spoofing can gradually shift a platform's perceived position without detection.
Every autonomous system, military or commercial, requires continuous, reliable positioning. From the 35,000+ military drones to 33 million projected autonomous vehicles by 2040, the demand for GPS-independent navigation is universal.
Battlefield Necessity
In contested urban environments, GPS availability drops below 40%. Precision-guided munitions, autonomous ISR platforms, and ground vehicles all require navigation that cannot be denied by a $30 device.
Multi-Modal Navigation Fusion
Four complementary sensor modalities fused through a federated Extended Kalman Filter.
Celestial Navigation (Star Tracker)
Miniaturized CMOS star tracker matches observed patterns against 58,000-star catalog. Provides absolute attitude (1 arcsecond) and position. Immune to jamming, no emissions, works at any location. ML-enhanced for daytime and thin-cloud operation.
Magnetic Anomaly Navigation (MagNav)
Vector magnetometer array with sub-nanotesla precision correlates against high-resolution magnetic anomaly maps. Passive, works underground/underwater, cannot be spoofed. Maps stable over decades. 50-100m accuracy in surveyed areas.
Inertial Navigation (IMU)
Navigation-grade MEMS IMU with fiber-optic gyroscope augmentation. 400Hz 6-DOF motion tracking provides the continuous "backbone" between absolute fixes. Completely self-contained, no external signals required.
Terrain-Relative Navigation (TRN)
Dual-mode radar altimeter + SAR imaging. Correlates observed terrain against DTED databases. All-weather operation. 5-10m accuracy in varied terrain. Complemented by celestial/magnetic over flat terrain.
GPS Alternatives: A Multi-Billion Dollar Infrastructure Need
Integrated Multi-Modal vs. Single-Sensor Approaches
vs. Enhanced INS (Honeywell, Northrop)
Pure inertial systems drift unbounded without aiding. NORTH STAR's four modalities continuously bound drift, keeping error below 10m indefinitely.
vs. Vision-Based Navigation (BAE, L3Harris)
Camera-based systems fail in darkness, fog, and smoke. NORTH STAR operates in all weather through radar-based TRN and passive magnetic/celestial sensing.
vs. eLoran / Pseudolite Systems
These require infrastructure deployment (transmitters). NORTH STAR is fully self-contained, no infrastructure, no external signals, no dependencies.
Federated Fault Tolerance
If any sensor fails, the system automatically detects and excludes it. Graceful degradation across all environmental conditions, no single point of failure.
