What Does GCO Stand For?
GCO stands for Ground Checkout
GCO, or Ground Checkout, refers to a systematic process used to verify and validate the functionality of spacecraft systems and components before launch. This critical phase ensures that all equipment operates correctly and meets safety and performance standards, providing confidence in the readiness of the mission. Ground Checkout typically includes a series of tests, inspections, and evaluations conducted on the ground, allowing any issues to be identified and addressed prior to liftoff.
