Solve all Narrow-Lane ambiguities at once with LAMBDA method #8

Open Andybty opened 1 year ago

Andybty commented 1 year ago

What I want to express is that when using the lambda method to fix narrow-lane ambiguities, shouldn't we use the variance matrix of the narrow-lane ambiguities? However, the code uses the covariance matrix of ionospheric single-difference ambiguities. Will this have an impact on the positioning results?

I will check this. If there is an effect on the positioning results, I guess it can be only on the convergence behavior. The coordinate results indicate that the ambiguities are correctly fixed.
