With firmware 1.13 how should I configure simplertk2b to use SBAS when RTCM messages are not available?
Can I use 10Hz rate as NMEA output when GPS, Glonass, Galileo and SBAS are enabled?
It should enable SBAS by default, and will use RTCM3 data when available. With SBAS CEP99 looked to be just under a metre. Real concern is abrupt position change from 3D/DGNSS to FLOAT/FIX
I expect 10 Hz would be sustainable. Personally I’d cull a lot of the sentences as they are just noise. Set GSV rate to 10 so it comes out at 1 Hz
If you get “txalloc failure” warning check your baud rates, and message loadings, especially on otherwise unused interfaces.
Using WAAS
Did some test with SBAS (EGNOS). No matter if SBAS is on or off, the results are the same after 2,5h test; deviance is about 1m.
