MODERN METHODS FOR THE DETERMINATION OF POLAR MOTION AND UTI

William E. Carter

Abstract:	This paper is organized into two major divisions according to the topics: polar motion and UTI. Each division is introduced with a brief review to provide a minimal perspective for readers unfamiliar with the subject area. The applications of Doppler satellite observations, laser ranging to artificial satellites and the Moon, and astronomic radio interferometry to monitoring polar motion and UTI are discussed. Emphasis is placed on detailing how and what each method is capable of measuring, fundamental limitations are noted, and the present status of the development of each method is reviewed. The paper concludes with a summary of the author's evaluations of the various methods as candidates for the next generation international polar motion and UTI monitoring service.
