Yes, they do. They seem to use different orbital, gravity, geoid, TAI, etc models. Trying to merge fixes from different systems leads to all sorts of problem, particularly at nuttery levels. I've seen reports that GPS and GLONASS fixes can be off well over 50 meters when referenced to the same map model.
