Impact on Positioning: Solar Flares

Please be advised that if you are using our GNSS-related products, you may experience the following issues.

- Missing loss of GNSS FIX,
- inaccurate positioning despite having a GNSS FIX.
- location information Machine devices.

A large solar flare event was confirmed on Tuesday, November 11, at 19:04 JST. (10:00AM UST)
This event resulted in multiple observations of large-scale coronal mass ejections (CMEs) directed toward Earth. Some of the ejected coronal gas has already reached the vicinity of Earth, and additional coronal gas is predicted to arrive and pass through Earth within the next 1 to 2 days. This event may cause disturbances in the near-Earth space environment, ionosphere, and geomagnetic field. Potential impacts include increased errors in high-precision positioning using GPS, interference with shortwave communications, and operational effects on satellites.
