NASA has repurposed the processor from the Ingenuity Mars Helicopter to help the Perseverance rover navigate autonomously on the Red Planet. The aerospace agency used the Helicopter Base Station's Qualcomm Snapdragon 801 chip, which runs 100 times faster than the rover's other systems, to create a new autonomous navigation system called 'Mars Global Localization.'

This system allows Perseverance to determine its position without phoning home to Earth, potentially enabling unlimited autonomous driving distances. The algorithm compares panoramic images from the rover's navigation cameras with onboard orbital terrain maps, pinpointing the rover's location within 10 inches in about two minutes. NASA has already deployed this technology in production, using it on February 2nd and 16th.

The upgrade represents a substantial improvement over the rover's current navigation tools, which can be off by up to 35 meters and sometimes force Perseverance to stop driving prematurely. The project overcame challenges including damaged memory bits in the repurposed processor, requiring NASA to develop solutions to isolate affected areas. This work demonstrates how commercial silicon can be effectively used in space applications, with NASA already looking toward applying similar technology for lunar missions.
