PPK mode with more than 3km baseline

[willstar_beleno (KAKAROT)]

in PPK mode with more than 3km baseline how many minutes should you obseved the point with open skyview. is 5 minutes is enough?

[wizprod (Christian Grüner)]

More than 3 km, is that then 3.5 or 10 km or?

[Zaz5400 (Zaz Villanueva)]

I would go for 25min rapid static.

I think 20 min is enough for multi frequency receiver but more time is better.
For a single frequency receiver 30 min is good.

Here is one recommendation from the IBGE (Brazilian Institute of Geography and Statistics) provided by mauricioranzan (Mauricio Surveyor) in another post.

Baseline for PPK

In Brazil we have this reference table from the IBGE (Brazilian Institute of Geography and Statistics). In this case of a baseline of 30km, according to the table, it would be 2 to 3 hours of tracking, but for multiband equipment. For single frequency, the limit would be 20km. This is for static lifting. [image]

last time i did ppk i notice that when the baseline is less than 1km 1-2min can solve fix, less than 2km 5min fix but more than 3km i observed it 5min solution is float.

There is a saying you may find in the scientific literature about the recording time in static mode. It is :
time = 10 minutes + 1 minute per kilometer of baseline + 1 minute per 100 meter of height difference

Hi @willstar_beleno,

5-10 minutes should be enough in good environmental conditions at a 3 km baseline. If you can achieve only a Float solution, please share the logs from the rover and base with me. I’ll check the data quality and try to post-process the data to see what can be wrong.
