A worldwide satellite navigation system (TIMATION) has been proposed that will yield instantaneous and continuous position fixes by suitable satellite configurations and navigator equipment. The TIMATION project is conducted by NRL under the sponsorship of the Navy Space Project Office (PM-16) and the Naval Air Systems Command. This report addresses the instantaneous position-fixing results obtained by using range and doppler measurements obtained with the TIMATION II satellite and a navigation receiver employing a relatively precise frequency standard. The results are corrected for first-order ionospheric refraction and indicate a two-dimensional position-fixing capability of 105 m RMS (60 m CEP). (Author).
