Base location extraction from rtcm data in rover

How to get base location in rover through rtcm data?
As per the Sparkfun library getLatestRTCM1005 API we’ll help to get base location in ECEF format(x,y,z) .Can we convert it into Lat Long format or utm and how accurate it is.
#Ublox_f9p 002B

I’m not sure I understand the question… Accuracy Verification - SparkFun RTK Product Manual and Creating a Permanent Base - SparkFun RTK Product Manual might be helpful (they also use f9p); we also have several extra examples here

WGS84
a = 6378137.0; // Semi-major earth axis (ellipsoid equatorial radius)
f = 1/298.257223563; // flattening
e = sqrt(f * (2.0 - f)); // eccentricity

thanks @TS-Russell .
Actually I’m not sure about whether rtcm data which rover continuously receive provide base location or not,if yes how to extract that ?

thanks @clive1 .
( getLatestRTCM1005 ) will this API in Sparkfun library giving base point only or other things also?

Hi Jasvinder (@jasvinder1079 ),

There are RTCM1005 examples in the v3 library:

The RTCM_1005_data_t struct is defined in u-blox_struct.h:

For a full understanding, you will need to purchase the RTCM Standard:

Thnks again @PaulZC

Hello @PaulZC ,
This is was through rtcm data to calculate base location points in rover. Is there API or method to get base points from rover directly instead through extracting rtcm frame?

Hi Jasvinder,

I do not think that is possible - with u-blox modules.

Best wishes,
Paul
