Thingy91 GPS without AGPS never acquires lock?

Arnout

Hi,

I was testing the GPS performance of the the thingie91. The default application (asset_tracker) works perfectly, but uses AGPS from the nordic cloud.

The asset_tracker_v2 does not use AGPS, and does not seem to lock in my case (even after 10+ minutes), even when positioning outside. 

When enabling constant printing of status, I can see that it does see some satellites, yet does not get the lock. (I'd expect it to first get the eph. data and subseqently (like < 5 min) get the lock anyway)

Is this behavior to be expected? Is non-AGPS tested on the thingy91? I am aware that I could still try to use an active GPS antenna to boost the signal, but since with AGPS it gets a lock immediately I was hoping this wasn't required when just waiting long enough.

Thanks for your feedback.

    Thanks a lot for your feedback, Arnout! May I ask if your Thingy:91 is registered to the network with PSM?

    Regards,

    Hi Markus & Markus,

    I switched to asset_tracker(_v1), with nordic's AGPS, and a fresh thingy91 to restart some GPS tests. (I've been taking BLE UART logs of the thingy while riding to/from work. The logs combined with the nordic cloud map give me a dataset to work with for getting a feel on how "stable"/fast the GPS locking is. I've ran the vanilla asset tracker demo as well as some modified code that just tries to get a lock or give up in 2 mins, and reboot. (To test "clean" gps performance))

    In fully open sky, after boot, I often manage to get a lock after 30-80s. (Never sooner than 30s)
    Subsequent locks -can- be much faster (even within a few seconds), but sometimes also seem to just "hang". (e.g. I can be waiting for minutes on a lock. Just give up and make it reboot, and then after 30s it gets the lock). There's little consistency in the behavior, but my feeling is that, with an open sky, if it does not get a lock within +- 90s, its better to just give up and retry. (Note that the periodic LTE data actually also serves as a "reset" for this it seems. After being "unblocked" it sometimes locks very quickly, while there seemed to be no progress before)

    Regarding your PSM question: As far as I understand the code explicitly enables PSM before doing the GNSS measurement. An example log file:

    (This is for asset tracker v1. I haven't yet tried to look into the v2 again, but I recall it enabling PSM as well?)

    Is there more for me to check (e.g. network parameters) regarding the PSM?

    For now, I'm planning to work in a mode (new pcb design) where the entire nrf9160 is shut down externally for long periods of time, and woken up sporadicaly . It then has to fully reregister to the network, and also get the GPS lock, and send everything to the cloud. In that mode, getting the gps fix asap is key, and the possible "hang" is of course pretty undesirable. 

    Do you guys have some guideline/tutorial on best practices with using the GPS in such a usecase? I checked that the asset tracker v1 does use "full power" GPS. Somehow it does loose the info it had before a reboot (takes 30s VS 3s after a previous lock -- some state is not maintained. (Question is how relevant the state would be after like 1 day though)). PSM should be enabled. Other stuff to take into account?

    Will keep you posted,

    Arnout

    Hi,

    (Btw for some bizar reaon, I cant reply to your exact post (buttons are just not there), so the page chronology looks really weird, but ok)

    Just to make sure that I got this right. You requested this after the GPS operation was enabled, right? 

    Yes, that is true.

    Albrecht Markus Schellenberger said:
    What SIM card/network provider are you operating with?

    I have this with both:

    - roaming sim card from "whereby" => uses belgium orange network

    - roaming sim from "olivia wireless" => uses belgium proximus network

    Kind regards,

    Arnout
