Construction of an X / S band for the Nigeriasat-2 mission control center and validation of the data from the satellite
A fully automated X / S-Band Mission Control Center (MCC) for the Nigeriasat-2 (N2) and Nigeriasat X (NX) satellites were built in Abuja. The construction of the customer center consisted of installing antenna and computer systems of a suitable size, which were used to control the entire satellite mission. The N2 / NX customer center consists of three main segments: the ground station (GS) for direct communication with the satellite, the mission control suit (MCS) for mission control and satellite telemetry and the mission planning system (MPS). It is used for satellite imaging tasks, data preprocessing and archiving .
T.The spatial image data obtained from the Abuja and Enugu MCC from the N2 and NX satellites was of specified quality with resolutions of approximately 5 m and 22 m, respectively. A comparative analysis of N2 and NX of geospatial data about the state of Abuja and Enugu and data obtained independently of SPOT 5 and Landsat ETM with similar capabilities showed significant similarities in terms of resolution and accuracy of the geographic position.
Early astronomers studied planet bodies and then developed beliefs, projections, and even scientific beliefs, that understanding the sun and planet bodies enables people to truly understand the earth in which we live. The search for the phenomena of the earth, the complexity of their nature, simple and complex. The interactions of its numerous features, among other things, provided great seductive impulses for the development of various ground-based devices and methods for studying and understanding other planetary bodies (Gruntman, 2004).
Advances in science have invariably led to the development of better techniques such as remote sensing for observing the Earth from space. Remote sensing technologies and techniques such as aerial photography and space observatories (satellites) have contributed to better information about the earth (Gleason et al. 2004). Remote sensing consists of using non-in-situ methods to view, measure and / or observe features of interest that cannot be seen with the naked eye.
Also used in remote locations that are physically inaccessible to humans or too large to explore or visit in time cost efficient Wise. Remote sensing devices use physical laws to “see” energy and spectral signatures of features across the electromagnetic (EM) spectrum or waves (both generated and induced) of different light and energy wavelengths (spectrum). The part of the EM spectrum that is visible to the human eye is a small band in the range from 400 nm to 700 nm.
