General Dynamics Mission Systems successfully tested its Multiple Orbit Navigation system on a hypersonic vehicle traveling at speeds above Mach 5 in GPS-denied environments. The trial with the Army Combat Capabilities Development Command's Aviation and Missile Center addresses a stated capability gap in alternative navigation for advanced platforms.
What's happening
- General Dynamics integrated its MO-Nav single-board navigation system into Stratolaunch's reusable Talon-A test vehicle for a flight trial at speeds exceeding Mach 5.
- MO-Nav combines multiple Global Navigation Satellite Systems, signals of opportunity, and position, navigation, and timing signals to enable navigation without GPS.
- The trial was conducted by General Dynamics Mission Systems with the Army Combat Capabilities Development Command's Aviation and Missile Center.
Why it matters
- GPS denial represents a critical capability gap across joint forces that programs face growing pressure to address through alternative navigation technologies.
- Demonstrating GPS-denied navigation on hypersonic platforms extends mission availability in contested environments and reduces dependence on satellite-based positioning.
- MO-Nav's software-upgrade model allows programs to update capabilities without new hardware insertions, reducing insertion timelines and lifecycle costs.
Going deeper
- Talon-A is a fully reusable hypersonic test vehicle with a launch weight of approximately 6,000 pounds, 27.9-foot length, and 11.2-foot wingspan, capable of autonomous landing on conventional runways.
- The vehicle can sustain flights at speeds up to Mach 6 and carries classified internal payloads to collect real-world mission data.
The intrigue
- The trial uses a reusable test platform, suggesting repeated demonstrations may follow to validate MO-Nav performance across different flight profiles and operational scenarios.
The fine print
- Program funding amount is undisclosed; capital type is program or policy investment from the U.S. Army.
