Single Dish Radio

The Ghana Radio Astronomy Observatory (GRAO), is the first of its kind in sub-Saharan Africa, apart from South Africa. The site has a 32-meter radio telescope, 16-meter, and 9-meter telescopes. It is located 5.7504 𝑁 and 0.3051 𝑊, 25 km North-West of Accra, at Kutunse, satellite junction off the Accra-Nsawam highway.

The 32-meter antenna operates at 5 and 6.7 GHz bands. It has a C-band ambient cooled receiver of ~110 K. The System Equivalent Flux Density (SEFD) is ~ 250 Jy.

Current projects include Science commissioning and verification, Methanol maser observations, and Pulsar timing programme. The 32-meter radio telescope produces cutting-edge observations across a wide scope of radio astronomy specialties, including methanol masers, pulsars, giant stars, supernova remnants, Active Galactic Nuclei (AGN
