We have two remote SensorStations in James Bay that have been operational 24/7, but the SensorGnome data is really sparse, collecting for only a few hours a day, if at all.
We know it’s been operational because we get daily Iridium check-ins that tells us it’s been running for several days, plus we downloaded the CTT GPS logs and it shows there are hourly hits collected every day.
The deployment plots for the two stations are below. You can see the reboot odometer does not update each time it starts collecting data, which helps confirm there is no reboot occurring. My best guess is that it’s as if the SensorGnome Control process is breaking and then restarting sometimes. I have asked our partners to download the SG logs next time they visit either station, but it may not be for a while due to how remote they are.
There is no SensorGnome - I’m asking why the SGdata is so sparse when the SensorStation gps and iridium logs say it’s been running continuously. The iridium check-ins for CTT-V3023D363BD7 are in the attached csv. The file rotate.zip contains the gps hits logged by the SensorStation and SGdata(1).zip is the raw data from the same station.
Do you know if they have the SS image that includes the FunCube fix. If I recall, when those failed it often affected the sg service as well.
The GPS fixes all line up with SG pules data, which does look like as a more general failure… (The deployment timeline plot will almost certainly be using the GPS data from the SG files. The SS also records GPS data. They both use the same module, so normally there wouldn’t be a difference, but it would be interesting if there are SS GPS fixes during those “dark” periods on the timeline)
The gaps in the boot numbers are very strange… They often skip every other number, though then again they are sometimes in the correct sequence.
Lucas, what kind of power setup are you using, and specifically what type of battery? We have some stations that look exactly like the second screenshot you have here, where in the colder parts of the year (and in some cases year-round) the gps bar is choppy and the station is rebooting daily. We have seen some correlation with using LiPO4 batteries, and my theory is that the onboard battery management system is causing the battery to shut down overnight when it’s even colder. See screenshots you can see in the receiver timeline what time of the day the active gps hits are coming through.
