LINUSS 1 is quietly practicing for a GPS system that doesn't orbit Earth — it orbits the Moon. Part of a two-satellite pair, LINUSS tests the navigation and positioning technology NASA will need for its planned lunar GPS network, LunaNet, meant to give future Artemis astronauts and robotic landers the same kind of reliable positioning on the Moon that GPS provides on Earth today. Right now there is no such system; a lunar lander has to navigate largely blind, using onboard cameras and pre-mapped terrain. LINUSS is a small, unglamorous first step toward fixing that.
