Why are my standardized residuals still high?

    Hi guys,

    I'm trying to process a static GNSS network and have been playing around with network geometry to get my height residuals down in the minimally constrained adjustment before progressing to a fully constrained.

    I'd like them to be below the 95% confidence factor of 1.96. TBC isn't flagging them as it is under its critical value. Everything else seems to be working okay.

    Any insight?

    Would you mind sharing your raw data?  I usually look to see what the minimally vs fully look like.  I have noticed that particular date/time has gleaned some less than favorable results lately and some slop in newly set NGS.

    These values look low (good) in this adjustment report.  How long were you observations? Download an ephemeris?
