Space Geodesy and Remote Sensing in the Southern Hemisphere

1.精密重力测量（1）根据昭和台超导重力仪（39.6 ° E，69.0 ° S）的观测资料，对长周期潮汐进行了分析，得到海潮改正的Mf和Mm δ因子为1.169 ± 0.008，明显大于01 δ因子（1.157）。(2)我们的研究结果是第一次估计的MF三角洲因素列入现实的海洋潮汐建模，并提交佐藤等人。（1）对昭和站SCARGPS标志点的VLBI和DORIS测定的ITRF 92坐标进行了比较，虽然有待于更精确的大地测量，但其对应的地心坐标最大偏差为12 cm。比较分析发表在Kanao等人（1995年）的《日本大地测量学会杂志》上。(2)对SCAR 92全球定位系统活动数据的分析在处理过程中继续进行。 ...更多信息 g软件进行了比较分析，结果表明：南极和南半球17个观测站的10天观测数据，X坐标与VLBI坐标相差10 m左右，Y、Z坐标在几厘米范围内基本一致，为此，我们正在对SCAR 95 GPS观测数据集进行比较分析。我们从1996年11月开始与澳大利亚地质调查局合作在莫森站进行潮汐重力研究。(2)我们正在讨论发起由Syowa站（日本）、霍巴特（澳大利亚）、O 'Higgins站（德国/智利）和Hartebeesthoek（南非）参与的南极VLBI活动。现状报告将由涩谷（1996年）在APT 95研讨会会议记录上发表。（3）完成了ERS-1/-2 SAR Tandem使命在南极上空的协调接收，并开始讨论建立数字高程模型（DEM）和进行冰动力学研究的国际计划框架。少

1.Precise gravimetry(1) From the superconducting gravimeter records obtained at Syowa Station (39.6ﾟE,69.0ﾟS), analysis of the long-period tides was made.The ocean-tide corrected Mf and Mm delta factors are obtained as 1.169 +- 0.008, which are detectably larger than those of the 01 delta factor (1.157).(2) Our results are the first estimate of the Mf delta factor with inclusion of the realistic ocean tide modeling, and are submitted by Sato et al.(1996) to the Physics of the Earth and Planetary Interiors.2.Reference frame(1) We mede comparison of the VLBI determined ITRF92 coordinates and the DORIS determined ITRF92 coodinates of the SCAR GPS marker at Syowa Station.Although accurate discussion awaits more precise geodetic tie, discrepancy of the corresponding geocentric coordinate was 12 cm at the largest. The comparison analyzes were published in the Journal of Geodetic Society of Japan by Kanao et al. (1995).(2) Analyzes of SCAR92 GPS campaign data were continued with the processin … More g software of GAMIT+GLOBK.Analyzes of 10 days data with 17 Antarctic and southern hemisphere sites yielded large discrepancy of 10m for the X coordinate as compared with the corresponding VLBI-tied coordinate.The Y and Z coordinates were consistent each other within several centimeters.Thus we are now analyzing SCAR95 GPS campaign data set for comparison.3.International collaboration(1) We started cooperative tidal gravimetric research at Mawson Station with the Australian Geological Survey Organisation from November 1996.(2) We are now discussing to initiate Antarctic VLBI campaigns with participation of Syowa Station (Japan), Hobart (Australia), O'Higgins Station (Germany/Chile) and Hartebeesthoek (South Africa). Status report will be published by Shibuya (1996) to the Proceedings of APT95 Workshop.(3)Coordinated receivings of ERS-1/-2 SAR Tandem Mission over Antarctica were made and discussion of international program framework started to make digital elevation model (DEM) and to study ice dynamics studies.
