Mission Planner - GPS Status parameter - "4" "5" "6" missing in docs

[jstroup1986 (Joseph G Stroup Jr)]

Testing RTK with a new F9P receiver I charted GPS.Stauts.

It seems that the levels “4” “5” and “6” are not defined in the docs. I suspect “5” is “float” and “6” is “fixed”. I’m not sure what “4” represents.

Hi,
I had the same question a long time ago, and found this post.

GPS Status = 4

From ardupilot/AP_GPS/AP_GPS.h /// GPS status codes enum GPS_Status { NO_GPS = GPS_FIX_TYPE_NO_GPS, ///< No GPS connected/detected NO_FIX = GPS_FIX_TYPE_NO_FIX, ///< Receiving valid GPS messages but no lock GPS_OK_FIX_2D = GPS_FIX_TYPE_2D_FIX, ///< Receiving valid messages and 2D lock GPS_OK_FIX_3D = GPS_FIX_TYPE_3D_FIX, ///< Receiving valid messages and 3D lock GPS_OK_FIX_3D_DGPS = GP…

0=No GPS
1= No fix
2=2D Fix
3= 3D Fix
4= 3DGPS
5=RTK Float
6= RTK Fix

Excellent - thank you!

I suspected as much.

I think the terms for 3D Fix and 3DGPS are also are sometimes stated as “GPS” and “DGPS”.

I found this reference that explains the differnece.
