Hm. I’m not quite sure I follow you.
It sounds like you have a sensor package that you deploy at one spot for a while, then you stop it, pack it up, and move it somewhere else. After some time, you move the sensor package back to the original site. Is there ever data being collected while it’s moving, or is the GPS data only being collected to help the technician remember where they were on any given day? If the data is only being collected in discrete chunks while the sensors are stationary, you could create multiple stations for each stopping point and then manually chop your data up by location and upload the chunks. It’s kind-of a pain in the bottom, but if the stations are unrelated except for the equipment you’re using to make the measurements, I think that is the appropriate way to handle the data.
