How LC29HBA temperature compensation feature should be used properly? Should I perform all actions specified in section 2.5 of Application Note before enabling temperature compensation every time I switch module on, or is it one-time procedure?
Blockquote
2.5. Temperature Compensation
Since the IMU is a temperature-sensitive sensor, the temperature compensation feature should be enabled
when the operating environment deviates by more than 25 degrees from the normal temperature.
Requirements to be met before using this feature: Run the LC29H (BA, CA) in open air for approximately 30 minutes, either stationary or moving. Ensure LC29H (BA, CA) experience a complete temperature cycle exceeding a 25-degree change,
such as transitioning from a low to a high temperature, or vice versa.
Did I understand correctly that I should run the module for 30 minutes at constant temperature, then heat it up by 25 degrees or more, and only after that perform steps 1 - 3? And I don’t need to repeat this procedure again after next cold start?
Should the module be calibrated and get GNSS fix during this procedure?
Hi @drauger
Q: Did I understand correctly that I should run the module for 30 minutes at constant temperature, then heat it up by 25 degrees or more, and only after that perform steps 1 - 3? And I don’t need to repeat this procedure again after next cold start?
A: Yes, you don’t need to repeat calibration for temperature compensation function.
Q:Should the module be calibrated and get GNSS fix during this procedure?
A: In open air, which means the module could get GNSS fix.
Run the LC29H (BA, CA) in open air for approximately 30 minutes, either stationary or moving.
