CONSTRUCTION OF X-S BAND FOR NIGERIASAT-2 MISSION CONTROL CENTRE AND VALIDATION OF DATA FROM THE SATELLITE

ABSTRACT

A fully automated X/S band Mission Control Centre (MCC) for the Nigeriasat-2 (N2) and Nigeriasat X (NX) satellites was constructed in Abuja. The construction of the MCC consisted of the installation of the appropriate size of antenna and computer systems used for the control of the entire satellite mission. The MCC of N2/NX consists of three main segments: the ground station (GS) used for direct communication link with the satellite, the mission control suit (MCS) used for mission control and satellite telemetry and the mission planning system (MPS) primarily used for satellite’s imaging tasks,  data pre-processing and archiving. The geo-spatial image data obtained from the MCC of Abuja and Enugu from the N2 and NX satellites were of specified quality, with resolutions of approximately 5 m and 22 m respectively. Comparative analysis of N2 and NX of geo-spatial data over Abuja and Enugu state and data obtained independently from SPOT 5 and Landsat ETM, with similar capabilities, showed considerable similarities in resolution and geo-location accuracy.
