No GPS data or same coordinates for all the pictures

Hi everyone,
I’m trying to get some help about a GPS issue with Sequoia+ and Sunshine. Most of the time, there is no GPS data acquired by the sunshine. The DEL stays yellow… Some times the GPS works and I can see it in the status page of the html interface but after taking pictures, all the pictures have the same coordinates (coordinates of the first gps fix). I tried to reset the Sequoia and then update the firmware but the problem is still here, since the the first use of the camera.
Would you have any advice to solve this issue ?
Thank you very much for your help !

Hello,
I has a similar problem with my sunshine sensor. I found that the error occurs when the sensor is exposed to direct sunlight. I covered the sides of the case with black tape, only the red part - the black cover seems to be dark enough. For me this totally solved the problem.

Hi, Hubertus,
Thank you very much for your suggestion, unfortunately, that doesn’t work for me… Still not GPS data…

Damien,
what is the situation when you totally cover the sensor with something dark? And what does the status page in the web-interface show when there is no GPS-data? In my case the IMU (roll/pitch/yaw) of the sunshine sensor also freezes.

Hi Hubertus,
The sunshine’s IMU and incident light sensor work well, even when GPS is “frozen”.
I tried your suggestion and started the Sequoia with the sunshine fully covered with black tape and a miracle happened ! The GPS data were acquired and streamed correctly. Then I tried to restart normally the Sequoia without black cover on the sunshine and again, the GPS has worked normally. I can’t understand why, but it seems that a first GPS fix in the dark can debug the sunshine. I will do, next days, trials on the field to confirm that. But this is already a giant step that has been made thanks to you !
Thank you very much, Hubertus, you really help us !
