| Abstract: | Within the scope of problems concerning orbit computation, our study is based on information obtained from the set of measurements performed during one satellite pass within visibility of a tracking station.At best, this information is restricted to a number of geometrical components which are studied and interpreted. It is the aggregate of the set of geometrical components obtained during the set of passes which allow orbit computation to be performed.The quality of this information is then examined, i.e. the precision of geometric components obtained and factors liable to have a negative effect.Signature errors of elementary measurements performed during each pass and which may seriously impair orbit computation are finally considered.Once these signatures are known, a valuable tool is held for the specification of localisation measuring instruments according to desired performance in orbit computation.The cases of range and Doppler type measurements are examined here. |
