Nordic Cloud GPS

[KyeongTaek Jeong]

Why can't I see GPS?

but I can see LTE Link App

I wonder why these two are different.

[Martin Lesund]

Hi KyeongTaek,

Correct, the location shown in LTE Link Monitor is based of the eNB (basestations) location, and the one in nRF Cloud is gathered from the GPS. 
What application are you running on the nRF9160?
nrf Cloud A-GPS sample

or

Asset Tracker application

When using GPS it is recommended to go outside with the device. 
If you are using the nRF9160DK It is recommended to use an external GPS antenna such as the Molex:

Since the on-board GPS antenna on v0.9.0 and older is not the best performance.

best regards,

Martin L.

I used "asset Tracker application" now, but I have a question

What does the log shown below mean? And what is the solution?

Hi,
The log means that the application is constantly searching for GPS satellites, but because you are either using the on-board antenna and/or are located inside then the GPS is not able to get a FIX. (Position data)

Therefore it wont send GPS data to the cloud.
