How rugged industrial camera technology supports image-based navigation beyond Earth

The Challenge

A crewed spacecraft operating beyond low Earth orbit must be able to determine its position and trajectory even when communication with Earth or ground-based navigation support is unavailable. For NASA’s Orion Multi-Purpose Crew Vehicle (MPCV), optical navigation uses images of celestial bodies—including Earth and the Moon—as inputs to the spacecraft’s navigation process. Camera hardware for this role must meet demanding performance requirements and remain functional in the severe environmental conditions associated with spaceflight.

The Imaging Solution

According to Navitar’s published case study, NASA selected Pixelink industrial camera technology for the Orion Optical Navigation System. The navigation camera system is positioned in three locations on the spacecraft and captures images of Earth and the Moon during launch and re-entry. These images support the spacecraft’s ability to calculate its position and velocity in cislunar space, including circumstances where communication or ground-based navigation is lost.

Navitar identifies the camera configuration as a 5-megapixel CMOS camera with a 1-inch optical format and USB 3.0 interface. Ruggedized packaging and housing were used to address the harsh conditions of spaceflight. The cameras were tested against vibration, temperature variations, radiation, shock and vacuum pressure.

How Image-Based Navigation Supports the Mission

1. Image acquisition: cameras capture views of Earth and the Moon at relevant mission phases.
2. Image-based estimation: optical navigation software uses the observed celestial-body imagery and its geometry as inputs to estimate spacecraft position and velocity.
3. Navigation resilience: the capability supports independent navigation and return-path decisions when ground communication or ground-based navigation information is unavailable.
4. Environmental qualification: camera hardware is evaluated against severe vibration, temperature, radiation, shock and vacuum conditions.

Operational Significance

The Orion example demonstrates how industrial imaging technology can be adapted for a mission-critical space application. Robust camera packaging, image capture capability and qualification for demanding environmental conditions are important when camera data contributes to navigation decisions. In this case, optical imaging is part of a broader navigation system; the camera alone does not calculate the spacecraft trajectory.

• Supports image-based position and velocity estimation using Earth and Moon imagery.
• Adds a navigation capability that can be valuable when communication or ground support is unavailable.
• Shows how commercial industrial camera technology can be integrated into specialized aerospace systems.
• Highlights the importance of environmental testing and ruggedized packaging for reliable operation.
