摘要：

非洲甚长基线干涉测量网络（AVN）是一个泛非洲项目，将通过将现有的电信天线转换为射电望远镜或建造新的天线，在非洲大陆的几个国家发展甚长基线干涉测量（VLBI）观测能力。本文重点介绍Nkutunse卫星通信站（加纳阿克拉附近）的转换，特别是早期的机械和基础设施升级，以及定制环境接收器和数字后端的开发。本文最后指出，在该站可以作为一个业务VLBI站投入使用之前，还需要做些什么。

英文摘要：

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.
