WebAstrometry is one of the most limiting factors in revealing complex multi-wavelength structures of sources. The precise determination of the offsets between the radio and optical emission relies on accurate astrometry. For example, the HST absolute astrometry has a typical uncertainty of 0.2”–1”, which is greater than the angular resolution. WebApr 4, 2024 · The wide-field telescope is a research hotspot in the field of aerospace. Increasing the field of view of the telescope can expand the observation range and enhance the observation ability. However, a wide field will cause some spatially variant optical aberrations, which makes it difficult to obtain stellar information accurately from …

WebThe line-of-sight astrometry provided by radar is orthogonal to the plane-of-sight optical astrometry, making the combination a powerful tool for refining orbits. A single radar measurement can often extend the useful lifetime of an orbital solution by ∼200 years. This prevents objects from being lost, and allows careful tracking of ...
