Abstract :
In the rocket launching site, there would be extremely harsh electromagnetic environment, and the test signal, reaching to the control center via long-distance transmission, will stack a lot of noise signal so that it will impact on test accuracy. The design is Committed itself to improving the temperature measurement system anti-jamming capability.
