Technical Support and Questions

Hi, I have a Multispec v1.0 (v 1.23, RIDES protocol). Recently, after android (v7.0) and photosynq software ( 2.03 - build 03) upgrade, I have a problem with GPS. On each sampling session, only geographical coordinates of the first measurement are correct. Then, the values of longitude and altitude not change till the end of sampling. My Samsung phone applications and sensors (google maps, etc) work well. Would be so kind to help me with this problem ?

Hi Wojciech,
I have asked the Help Desk about this problem, but it seems you are the first one reporting. I have a few questions: Do you have the project with data uploaded, so I could take a look? I assume you are making measurements in different locations that are far enough apart between? Is there any military base nearby?
Thank you. --Atsuko

Hi Atsuko, Thank You very much for a quick answer. I established a new project to show the problem: wojciech_misc. Please look also wojciech_test. The measurements have exaxtly the same longitude/latitude but in fact they are spread within ca 100 meters (my location sensor show the accuracy 13.5-30 m). I did measurements in this area Poland/Czech Republic border last year and I'm able to locate my plants with very high resolution. Even I this year's campaign in the first day all measurements were properly located. I think the problem starts after automatic upgrading of the android. I also tried the other cell phone, but this not improve results. As I work mainly in the field the location function is very important for me. I would be very grateful for help.
best regards Wojciech

Hi Wojciech,
Thank you for the detailed description. It sounds like the download of a new app was incomplete somehow. Would you report this to support@photosynq.org for a record? I will also contact the app developers. Thank you. --Atsuko

Hi Wojciech,
we have released a new version of the Android App, where the issue should be addressed. Please update the app through the Google Play Store.
