Thanks you for the information Sigurd. I look forward to the next release 🙂

[quote userid="75438" url="~/f/nordic-q-a/48710/gps-current-drain-values-in-ops---nrf9160"]Are these measurements the accurate expectations of the current drain so long as AT%SYSTEMMODE is still set as GPS mode?[/quote]

They are accurate, but for continuous tracking with PSM, the GPS is active during LTE PSM/sleep intervals. Continous tracking will give you a GPS fix every ~1 sec. If you don't need a fix every 1 sec, you could set it to e.g. every 10 sec, and you will get lower current consumption. In the upcoming v1.0.0 release of the modem fw, GPS+LTE mode can be enabled concurrently.

[quote userid="75438" url="~/f/nordic-q-a/48710/gps-current-drain-values-in-ops---nrf9160"]Is it possible for this to work while using the nRF9160 to run the application and process the data[/quote]

Yes, this is fully possible. This is one of the benefits with the nRF9160, it has a dedicated CPU for the application, the modem is running on a separate CPU.

[quote userid="75438" url="~/f/nordic-q-a/48710/gps-current-drain-values-in-ops---nrf9160"]Are there any plans to demonstrate the PSM version of the GPS code in future releases of the SDK?[/quote]

Yes,but the feature will likely first be shown in the Thingy:91 SW example.

Thanks for the reply.

Will this be part of the release that will have the ability to run both NB-IoT and GPS at the same time or are they to be released seperately, with this being a new repo tag?

Would I be able to get an answer to the other question about the current drain values? 🙂

Hello, it will be supported in the asset tracker in a future release, it's scheduled for the end of the month.
