The main purpose of this article is to present the idea of using Multi-process models as a method of detecting errors in GPS observations.

The theory behind Multi-process models, and. double differenced phase observations in GPS is presented shortly.

It is shown how to model cycle slips in the Multi-process context by means of a simple simulation. The simulation is used to illustrate how the method works, and it is concluded that the method deserves further investigation.
