I'd be very surprised if its exact position in the sky is not public information.
Even if not, it should be fairly straightforward to compute its position from the initial flightplan. Once it escaped Jupiter its trajectory is just a straight line.

I honestly don't know that we understand gravity well enough to keep this close of track of this small of an object for so long. Plus all the effects of the "negligible" gravities of nearby objects have to add up over time, and we can only include so many bodies in our N-bodies simulation, right?
I was about to say that Voyager likely also suffers from the Pioneer anomaly, which is suspected to be caused by the RTG's thermal radiation pushing the craft off course [1]. But according to wikipedia we can't really tell because the effect of the maneuvering thrusters that keep Voyager aligned is much bigger than the Pioneer anomaly (Voyager 1 has fuel until about 2040).
