I´ve got an 16481 SparkFun GPS-RTK-SMA Breakout - ZED-F9P (Qwiic) set as base as the very useful tutorial (how-to-build-a-diy-gnss-reference-station).
RTCM MSM 7 Messages flow is:
Sparkfun 16481 → USB cable → W10 Dell Laptop → SRVSTR (OPT: conversion RTCM3 to RTCM3, message output 1004(1),1005(1),1012(1),1230(1)) → RTK2GO Caster
I got fixes on the Hemisphere S320 rover randomly. Sometimes it works well a couple of minutes but turns autonomous mode for 5/10 minutes and then return to fix again. Sky clearview contidions are the best for base and rover. Hemisphere collector software is SurvCE and shows decimal values for latency quality parameter at moment it works autonomous and integer values at the moment it gets fix solution. It smells like something about synchro is not working well but I dont know.
Have you any idea of what am I doing wrong? Is there any uncompatibility between ZED-F9P RTCM3 MSM messages converted to legacy RTCM 3 messages for Hemisphere S320 rover? The same happens using SNIP instead STRSRV (parsing and converting MSM 7 messages to legacy RTCM3.
Broadcasting differential corrections the same way but with my old Hemisphere S320 as a base everythings works perfect. The only difference is that SRVSTR set without conversion because base and rover works with old legacy RTCM messages.
Thanks a lot in advance for your help
