[Lukáš]

Hello,

what is the update rate of the GPS in the nRF9160? This is something that I couldn't find in the provided data sheet.

Thanks!

 Hi Andreas,

thank you for the quick reply. I know that the GPS functionality isn't ready yet, I read the development status. However, I just wanted to know what could be the possible update rate of the GPS, to get the coordinates. Simply, if I would be able to obtain GPS position every two seconds etc.

I am asking because there are already some specs related to the GPS - time to fix, sensitivity, accuracy...

Thanks!

Hi.

Have you looked at the GPS receiver section in DocLib?

Or is this not what you are looking for?

Best regards,

Andreas

Yes, that's what I was talking about. There are some specs, but not related to the update rate if I understand them correctly.

There is something related in "Modes of operation" and "Performance" section:

• Position fix per fixed interval, e.g. 2 minutes (starts with cold start, sequential fixes with hot start)

So what is the minimum fixed interval that can be set? Does it have anything common with this?

• Acquisition time: 30 seconds for cold start, 5 seconds for hot start

Does it mean that I can only get GPS position every 5 seconds? It seems a little odd to me.
