A new technology from #NASA #JPL enables #Perseverance to figure out its whereabouts without calling humans for help.

Dubbed Mars Global Localization, it features an algorithm that compares panoramic images from the rover’s navigation cameras with onboard orbital terrain maps, and runs on the CPU originally used by Perseverance to communicate with #Ingenuity. Calc's a fix in 2min with 25cm accuracy.

NASA’s Perseverance Now Autonomously Pinpoints Its Location on Mars

Using the new Mars Global Localization algorithm, NASA’s Perseverance rover can now pinpoint its exact location without help from engineers on Earth.

Also worth mentioning is the fact that #Ingenuity's base station assembled out of COTS parts has suffered only the loss of 25 bits of memory out of 1 GB of RAM, which were isolated so that the new MGL algorithm could run.

The little #MarsHelicopter concept, including its innovative design both in aerodynamics and in electronics, proved to be much more useful than initially anticipated. No fanfare, big budget or hype, just very capable and passionate people doing their best.
