摘要：

ASTRA（天体测量和相位参考天文学）是现有凯克干涉仪的升级版，旨在提供新的自相位参考（高光谱分辨率观测YSO）、双场相位参考（灵敏AGN观测）和天体测量（强场状态下已知系外行星系统特征和银河系中心广义相对论）能力。随着第一个高光谱分辨率模式现在提供给社会，这方面的贡献集中在双领域和天体测量模式的进展。

英文摘要：

ASTRA (ASTrometric and phase-Referencing Astronomy) is an upgrade to the existing Keck Interferometer which aims at providing new self-phase referencing (high spectral resolution observation of YSOs), dual-field phase referencing (sensitive AGN observations), and astrometric (known exoplanetary systems characterization and galactic center general relativity in strong field regime) capabilities. With the first high spectral resolution mode now offered to the community, this contribution focuses on the progress of the dual field and astrometric modes.
