no double-differenced residual #369

Open moonlightfall opened 6 years ago

moonlightfall commented 6 years ago

I always get error:no double-differenced residual.and the solution sometimes single never got float or fix. I use ublox NEO-M8T as base, sony CXD5603 as rover, ublox output ublox raw data and sony output RTCM3 data. sony get the carrier-phase value as 0. is this the reason??

What's the CXD5603 receiver? Could you point me to some technical documentation about the receiver?

Is the carrier-phase always zero?

CXD5603 is a sony GPS receiver, have some APIs to provide GPS info. I can get the carrier-phase now.then the solution become always float but fix just seconds. The error messages always get: 1.outlier rejected 2.slip detected forward 3.large residual 4.ambiguity validation failed 5.not enough valid double-differences why is this??

Difficult to say, can you convert the file to RINEX and share it here?

What type of environment are you logging data?
