Robust Control Applications in the Global Positioning System

Abstract

Two students, Arrash Hassibi and Meeko Oishi, were supported during the period of this grant. Dr. Hassibi worked on several topics, all related to the toxic of the AASERT award and its parent AFOSR grant Meeko Oishi worked on the topic of switching in nonminimum phase systems with application to a VSTOL aircraft, as relates to hybrid systems. In this research, the problem considered was the parameter estimation in linear models when some of the parameters are knoWn to be integers. Such problems arise, for example, in positioning using carrier phase measurements in the global positioning system (GPS), where the unknoWn integers enter the equations as the number of carrier signal cycles between the receiver and the satellites when the carrier signal is initially phase locked.
