This sounds exactly what a Bayesian estimator is good at. I can give you
a good explanation of Bayesian estimation because of lack of time, and
the info on the net is definitely sparse (try wikipedia, but the article
is hard to read). It is good to know that if your problem is linear, and
your noise is Gaussian, you can use a Kalman filter
(http://www.scipy.org/Cookbook/KalmanFiltering).
