I am trying to use third party apps like Nuwa, Survey Master and Surpad, in some cases I have been successful in connecting via NMEA and/or bluetooth. However, I have been able to notice that the number of satellites shown in the app is much less (I see 8 sat) than what can be seen in the reach panel (I see 33 sat).
What I can be doing wrong? Is there a setting I’m missing?
In SURPAD 4.2
Thanks for answering.
At some point I thought it was something from Talker ID, however I am seeing that when selecting GN or GP in the Talker ID I have no variation in the third-party app, regardless of the selection I do not see the GPS constellation in the third-party app .
Do I get it right that you use Lefebure to get Reach coordinates in third-party apps via NMEA? If so, please check what satellites’ number Lefebure shows. Most likely, Lefebure displays fewer satellites than you see in Reach Panel. Hence, fewer satellites you see in third-party apps.
I understand that when the third-party app does not have a direct connection to NMEA and only access to the internal GPS of the mobile, then I must use Lefebure to make a mock location. In any case, Lefebure also reads me a smaller number of satellites than I can see in the reach panel.
So, that’s the reason you see less satellites in third-party app. Most likely, Lefebure shows the number of satellites used for calculating the solution, and transmits it further. In the meantime, Reach Panel shows all observed satellites.
According to your screenshots, SNR is pretty low, so I assume the sky view was partially blocked. Just in case, you can check the number of satellites in an open field. I believe it should be more than 8 in the range of 10-15.
