标题： The African Very Long Baseline Interferometry Network:The Ghana Antenna Conversion

摘要： 非洲甚长基线干涉测量网（AVN）是一项泛非计划，旨在通过改造现有的电信天线成为射电望远镜，或者建造新的天线，在整个非洲大陆的多个国家发展甚长基线干涉测量（VLBI）观测能力。 本文重点介绍了加纳阿克拉附近的努库特恩赛卫星通信站的改造工作，特别是早期的机械和基础设施升级，以及定制环境接收机和数字后端的发展。 文章最后概述了在该站能够作为运营中的VLBI站投入使用之前仍需完成的工作。 显示英文摘要

摘要： The African Very Long Baseline Interferometry Network (AVN) is a pan-African project that will develop Very Long Baseline Interferometry (VLBI) observing capability in several countries across the African continent, either by conversion of existing telecommunications antennas into radio telescopes, or by building new ones. This paper focuses on the conversion of the Nkutunse satellite communication station (near Accra, Ghana), specifically the early mechanical and infrastructure upgrades, together with the development of a custom ambient receiver and digital backend. The paper concludes with what remains to be done, before the station can be commissioned as an operational VLBI station.
