The radio emitting X-ray binary GRS1915+105 shows a wide variety of X-ray and radio states. We present a decade of monitoring observations, with the Rossi X-ray Timing Explorer-All Sky Monitor and the Ryle Telescope, in conjunction with high-resolution radio observations using Multi-Element Radio-Linked Interferometer Network and the The Very Long Baseline Array. Linear polarization at 1.4 and 1.6GHz has been spatially resolved in the radio jets, on a scale of ∼150 mas and at flux densities of a few mJy. Depolarization of the core occurs during radio flaring, associated with the ejection of relativistic knots of emission. We have identified the ejection at four epochs of X-ray flaring. Assuming no deceleration, proper motions of 16.5 to 27 mas per day have been observed, supporting the hypothesis of a varying angle to the line of sight per ejection, perhaps in a precessing jet.
