RTKGPS Android

Asalviano
Test with L1/Ntrip and L1/L2 post process



RTKGPS Android and LEA-4T Bluetooth

RTKGPS Android and LEA-4T Bluetooth 2

L1/Ntrip with LEA-4T Bluetooth with Android RTKLIB, RTKGPS by Illarionov, after 38min this fixed, at 20,8km from Caster IBGE/NTRIP/POAL (not recommend to be long range)

Coordinates (WGS84):

-30º 08' 09,151141"
-51º 19' 24,0859"

Them, the same point with Trimble 4800, postprocessed at Trimble Business Center with POAL base,  20,8km, 1:15H tracking:

Trimble 4800 at same point


Coordinates (WGS84)

S 30° 08' 09,15219"
O 51°19' 24,08695"

Distance between same point, L1/NTRIP  and Trimble 4800 L1/L2:

3,8cm

Conclusion: very good.

Static test.

Unfortunately, I deleted raw files from UBLOX LEA-4T BT rover. I would turn it into RINEX and post-process to compare with ntrip too. maybe next test...

You’ll also need to set your R8 to output RT17 if not already set to do so. And since it’s an R8-2 (?), be sure that it is set to output RT17 only, not RT27. Don’t forget to enable streamed Ephemeris too.
