Difference between satellite IDs in $GNGSA and $PSTMSAT

[Yegor]

Hello,

I noticed an inconsistency between standard NMEA output and proprietary ST messages.

In the log below, $GNGSA reports satellite ID 70,86,71:

$GNGSA,A,1,70,86,71,,,,,,,,,,94.9,94.9,1.0*20

 

But a few milliseconds later, the proprietary messages report:

$PSTMSAT,82,02399316,-50177,-2124377,11567958,22642190*59

$PSTMSAT,83,01208337,-46796,16872637,04587718,18599066*48 

$PSTMSAT,91,01369206,-46462,17701289,03680361,18063030*47

 

My question is: why does $GNGSA show satellite ID 70,86,71, while $PSTMSAT shows 82 and 83 and 91?

Is this expected behavior, and is there a documented mapping between the GSA satellite identifier and the PSTMSAT satellite identifier?

I could not find a clear explanation in the documentation. Any clarification would be appreciated.

Can you tell me which product you are using ? Teseo LIV3F?

What constellations have you enabled?
