In order to promote metrology technology of geometric error based on GPS, a digital metrology system of geometric error based on Linux embedded platform was developed. Results show that the digitized estimation result of products＇ typical geometry characteristic （such as： roundness error, cylindricity error, surface roughness and so on） is accurate and reliable. Because of being carried easily, the system can promote greatly new GPS application in engineering practice.
