Meet Dr. Gladys West
Most people use GPS without knowing that some of its accuracy rests on the work of a brilliant Black mathematician named Dr. Gladys West. Her calculations helped scientists develop a more precise model of Earth, laying essential groundwork for the satellite technology that guides phones, airplanes, ships and emergency responders today. She did not invent GPS alone, but the system millions depend on would not be the same without her contribution.
Many of us rely on GPS technology every day without realizing the immense mathematical genius behind its accuracy. Dr. Gladys West, a pioneering Black mathematician, played a key role in refining the Earth’s mathematical model, crucial for the precision of satellite navigation systems. Her work involved complex calculations to account for Earth's shape and gravitational variations, which are essential to how GPS satellites provide location data. From my own experience, understanding the history behind technologies we take for granted deepens my appreciation for the people who contributed to their development. Dr. West’s story highlights not only her intellectual contributions but also the challenges faced by Black women in STEM fields during her time. Her dedication exemplifies how perseverance and brilliance can create lasting impact, influencing the safety and efficiency of air travel, maritime navigation, and emergency response efforts worldwide. Learning about Dr. West’s role reminds us that GPS is far more than a convenience—it is the result of intricate scientific collaboration and innovation. This knowledge inspires me to value and support diversity in science and technology, recognizing the hidden figures whose work shapes our modern world.
