nRF9160: Position accuracy, navigation update rate and few more queries

[Dinesh]

Hi,

Greetings!

We are exploring nRF9160 SIP DK and Thingy91.

Here we have understood that it has GPA and LTE-M.

We wish to use it for India region in moving objects e.g. vehicles.

We wish to understand or receives inputs on below.

Can anyone help us out?

1. What is position accuracy (in meters) and navigation update rate (samples per second or Hz) for nRF91?

2. Is LTE-M supported in India? If No what can be the alternative?

3. Can I receive position/location details from GPS and send these details to cloud at a rate of twice a second?

Thanks in advance.

Regards,

Dinesh

Hi,

 

1. What is position accuracy (in meters) and navigation update rate (samples per second or Hz) for nRF91?

Position accuracy can be read from the GPS data, and the best position accuracy can be found in our el specs:

https://infocenter.nordicsemi.com/topic/ps_nrf9160/gps.html?cp=2_0_0_7_0#gps_elspec

Data is pushed out once per second when tracking. 

2. Is LTE-M supported in India? If No what can be the alternative?

I am not aware of the current status. I would recommend that you contact your local carriers and ask.

I know that NB-IoT (ipv6 only) is available with some carriers in India.

  

3. Can I receive position/location details from GPS and send these details to cloud at a rate of twice a second?

No. When you are in a LTE Link, you can access the GPS only when in eDRX or PSM mode.

You cannot use the LTE connection simultaneously as the GPS is running, therefore the GPS is slotted into sleep periods of the LTE link. This means that the LTE link must be idle before you start the GPS.

 

Kind regards,
