Subject: [SLR-Mail] No. 148: start sending KSP SLR network data to CDDIS From: Hiroo Kunimori, CRL ******************************************************************************** SLR Electronic Mail 1998-08-31 14:00:00 UTC Message No. 148 ******************************************************************************** Author: Hiroo Kunimori, CRL Subject: start sending KSP SLR network data to CDDIS Dear Colleagues of Data, Operation and Analysis Centers I would like to start sending KSP SLR network data to CDDIS, including stations KSP-Koganei(7328), KSP-Kashima(7335), KSP-Miura(7337) and KSP-Tateyama(7339),from September 1 ,1998. Initial System Change and Configuration information, and a priori coordinates with eccentricity information including DOMES number for each stations are attached in Table 1-3 below. There are minor specification issues left in a system, and therefore production volume would not be high. We do our best to provide good quality of observations and would appreciate if you notify any irregularities in our data as soon as they become known. Best regards, Hiroo Kunimori =====Table 1.

Coordianates and Eccentricity information============= A priori coordinates are derived from preliminary analysis of Lageos1 and Lageos2 in ITRF94 and meet results those from VLBI coordinatates by about 5cm. Eccentricity vector which run from Marker to Reference Point are derived from extensive local survey conducted in 1996 and 1997. #1 DomesNumber Site-ID Site-Name station coordinates X,Y,Z ( marker position: in meter ) #2 eccentricity ( E, N, UP ; in meter) 21704M001 7328 KSP-Koganei -3941941.2442 3368169.5209 3702195.6779 29.0907 9.5543 8.9818 21701M002 7335 KSP-Kashima -3997484.3126 3276846.8432 3724296.6149 1.5286 10.0201 4.4394 21739M001 7337 KSP-Miura -3976161.6873 3377950.3829 3656687.3131 13.2109 2.5949 4.4437 21740M001 7339 KSP-Tateyama -4000955.1915 3375310.4429 3632200.8626 7.3239 -4.7334 4.4550 =======Table 3.
