You are describing what used to be called the "errors in variables" problem; now

The kind of weighting you describe does not solve this problem, as far as I
know. (I'd be happy to learn otherwise.) It is ordinarily used to accommodate
outcomes, not covariates, that are measured with unequal precision. In this
application, the weights are known as "analytic" weights (in Stata, "aweights"; see the -help- for "weights")

Incidentally, aweights are not allowed with Stata's logistic regression commands (except under version control). See these two messages for a brief discussion:
