Compiled by electronic enthusiasts: the reliability of the sensor is very high, especially for high-performance products for aerospace applications. However, human error is sometimes fatal. It seems that the reason for the explosion of the Russian Proton-M unmanned rocket is the wrong installation of the angular velocity sensor. On July 2, the Russian Proton-M unmanned rocket exploded after being lifted off. All three navigation satellites (used in Russia's Glonass GPS system) on the rocket were destroyed. Fortunately, no casualties occurred. In the end what happened? An Interfax news agency report on the accident investigation committee revealed that the angular velocity sensor was "wrongly connected" and sent erroneous data to the guidance system. The Russian Federal Space Agency has not confirmed the cause. A person in the investigation committee told Interfax that the committee is investigating various possibilities, including navigation system problems, engine failures, and rocket launch control errors. According to Interfax, regardless of the cause of the explosion, all three navigation satellites and instruments worth $ 1.3 billion have been destroyed. 17 seconds after launching, the rocket quickly deviated from the orbit. During the process, the rocket tried to correct it, but it suddenly fell and eventually exploded 2.5 kilometers from the launch site. (Author Carolyn Mathas, compilation: electronic enthusiast Jessieliu) Comments from foreign netizens: CMathas: A huge failure. It is generally believed that there are some tests and proper confirmation before the official launch. This huge loss could have been easily avoided. DrQuine: The key connector can only be assembled in one direction to prevent reverse connection. Of course, it doesn't help if the connector is reversed. The second key is to collect benchmark data and confirm correct operation. If the sensor is upside down, the instrument should report the upside down data when launching the platform. Before a huge failure occurs, exhaustive testing will be of value if it can catch a small error.

_hm: The quality control of avionics is very important. Such errors occur from time to time. A common mistake is to reverse the polarity when installing polarized capacitors. Another element is testing. Testing is very important, it should try to include all possibilities. Of course, there are also error-proof system problems that must be avoided.
