Case: The Global Positioning System (GPS) [PDF]
Abstract : This case uses the development of the Global Positioning System (GPS) to help students develop skills related to decision-making using cost-benefit analysis (CBA). It is the purpose of cost-benefit analysis to weigh the benefits (or justification) of an investment or policy against the potential costs of the investment (or other alternatives)

Performances of a GNSS receiver for space-based applications [PDF]
Space Vehicle (SV) life span depends on its station keeping capability. Station keeping is the ability of the vehicle to maintain position and orientation. Due to external perturbations, the trajectory of the SV derives from the ideal orbit.
