A series of solution with quantum metrology technique and calculation metrology standard technique have been proposed to solve the problems in space vehicle measurement, such as the aerospace standard stability, linearity of multiform sensor output signal and time delay of electro pulse measurement. The electro quantum measurement accuracy can reach to 10E^-9 magnitude degree of uncertainty. The application of quantum standard can be used to measure resistance standard on space vehicle in short-term, then reckoning long term behavior, which is important for space vehicle stability controlling. The quantum standard can be used for calibrating sensors in mV level linearity and measuring time delay of pulse measurement in 10^-9s magnitude, which is important for space vehicle electronic propulsion system controlling.
