Abstract
This article reviews current state of the art reliability and cost effectiveness of spacecraft attitude and orbit monitoring. Failure analysis showed that more than 30% of spacecraft failures are due to attitude, orbit monitoring and control subsystem. Sometimes, the whole mission life time depends solely on this subsystem. Thus, spacecraft attitude and orbit monitoring subsystem design is considered to be challenge due to the high cost, high reliability requirements, limited power budget, processing budget and mass budgets usually associated with space missions. The monitoring system of spacecraft attitude and orbit consists of hardware and software components. This complicates the process of reliability calculation and implies the need for effective cost estimation methods.
