I don’t think you know what that word means. We’ve been measuring distances using such techniques for decades.

The Hipparcos satellite launched in 1989 was able to measure parallax angles for stars up to 1600 light years distance.
The ESA Gaia mission is expected to be able to measure parallax angles of about 10 microarcseconds. This will allow distances of 10 of thousands of light years to me measured with this technique.
Since the mission is only 6 weeks old and since we need to wait 6 months for the earth to swing around the sun to get the second measurement, we need to wait a bit before hearing there results.
