TIME SYNCHRONIZATION VIA THE TRANSIT SATELLITE AT MIZUSAWA

T. Hara, K.H. Sato

Abstract: Time signals omitted from Transit satellites have been received by the NACODE type receiver since 1974 at Mizusawa, Japan (station 027). By using these time signals, we can make a time comparison between the International Latitude Observatory of Mizusawa (ILOM) and USNO. TO complete time comparison by this method, many corrections are, however, necessary such as propagation delays, a receiver delay, effects of relative motion of satellites, effects of the ionosphere and so on. Provaration delays are calculated from the precise ephemeris of the satellite (30190) supplied by the Topographic Center of DNA. The receiver delay is measured by supplying a simulated signal to the space near the receiving antenna. Effects of the ionosphere on the propagation delays may be the order of one microsecond. Standard deviations of each pass are estimated to be 15.5 microseconds for the data UTC (ILOM) - C(OSNC) obtained in December 1976. Time comparisons by the Loran-system between ILOM and USNO are referred for a check of the Transit satellite timing method.
