- ck2 2y agotypically I'd link the NASA blog but it doesn't seem to be updating anymore! https://blogs.nasa.gov/artemis/2025/02/21/blue-ghost-prepares-for-landing-nasa-instrument-breaks-record/ https://blogs.nasa.gov/artemis/2025/02/21/blue-ghost-prepare... a little more insight in this article too https://www.floridatoday.com/story/tech/science/space/2025/01/15/nasa-science-ispace-firefly-blue-ghost-lander-spacex-launch-from-florida-kennedy-space-center-moon/77659308007/ https://www.floridatoday.com/story/tech/science/space/2025/0... Can anyone explain how the GPS signal is acquired if the sats are only pointing at earth? Is it because of sats on the edge that are broadcasting the radio wide 180 degrees and just a hole in the direct line-of-sight?

Details start at page 6 on the last link in this comment. I don't believe precise positioning on the Moon is occurring, only detection of where Earth is and consumption of the positioning signal the experiment can receive.
