Hello Thanks for using this app. This app is in fact in a very naive version and I am improving it..... But I haven‘t met your question.. One of the files collected by my Xiaomi MI 8 is like this: image I am very sorry for this bug... I will try to solve it.

First, I guess I made a mistake in setting the mi 8 and now it seems to be back to normal. I will continue to verify the accuracy of the data.However, it seems that Huawei mobile phones cannot accurately record data. I have attached the file.

In addition, I have added two other apps in the attachment, hoping to provide you with some comparative verification, so as to better improve the APP. What I want to know is how does the time synchronization between the camera and the gyroscope work?Because the other two apps seem to be synchronized to GNSS time or UNIX time.

Finally, if possible, I hope you will continue to add beidou B1I signal measurement functions,which will improve the positioning capability.

Anyway, this is a very commendable job and I will keep an eye on your work. Keep posted.

Best regards, Jiale Wang

Dear Jiale: Thanks for your advice and help. I am sorry I replied to you so late. I modified the app to collect the B1 signal and fix the bug that GPS L5 signals' LLI flag is always valid. You can turn to J.Z Huai‘s job to find how to synchronize the camera and imu. Now I am adding the function to collect magnetometer measurements.
Thank you very much. Best regards.

Thank you for all your work! I would like to know if you have now added the functoion to record magnetometer data and i really need it.

Jia-le-wang commented 2 years ago

@navlaw If you don't need a Camera, I'm guessing GnssLogger will do the job. (https://play.google.com/store/apps/details?id=com.google.android.apps.location.gps.gnsslogger&hl=en&gl=US)
