********************************** SITE INFORMATION FORM ********************************** 0. Form Prepared by (full name): Yehuda Bock Date : December 15, 1994) Report type : UPDATE (new contacts) 1. Site Identification of the GPS monument Site Name : Scripps 2 PGGA station 4 char ID : SIO2 (& S02Q - see note below) Monument Inscription : None IERS DOMES Number : 40460 M002 & M003 (see note) CDP Number : Not assigned Date : March 3, 1990 Additional information : PGGA - Permanent GPS Geodetic Array Note : IERS renamed SIO2 as S02Q & assigned new DOMES no. after Landers/Big Bear earthquakes of 28 June 1992 Note : SIO2 was built as a reference mark for SIO1, and for the first 2 years was used for survey ties and various receiver/antenna tests. When SIO1 was destroyed (June 1992) due to construction of new IGPP building, SIO2 became the primary Scripps site. SIO3, the new PGGA monument at Scripps, replaces SIO2 as the primary Scripps PGGA site. 2.
