I am working on a small satellite project which uses both of the MEMS IMU mentioned in the title in our hardware. I noticed that there is an huge difference in the temperature reading (around 11 degree Celsius) upon start up under room temperature condition. I understand from the datasheet that the temperature reading on the IMU not necessarily representing the external temperature, but I am still concern on the huge temperature difference as the tested hardware is our flight model that will be launced into space. This issue however is not present in our prototype model, showing only a 2 degree difference upon startup
Wonder is there any particular reason why is it so and is there any possible solution for the issue mentioned?
