Gladys West

Gladys West is a smart lady who invented something called GPS. GPS is like a map that helps people find their way by using signals from space. It's like magic, but it's really just technology. Gladys worked really hard to make GPS work better and be more accurate. She spent a lot of time doing math and making sure all the information was correct. Thanks to Gladys and her hard work, we can use GPS to find our way when we get lost.
