STATION "OBEC" DECOMMISSIONED - STATION "OB3C" NOW AVAILABLE
Global Navigation Satellite System (GNSS) Continuously Operating Reference Station (CORS), Eugene, OR
Since 2001, OBEC Consulting Engineers has maintained a Global Navigation Satellite System (GNSS) Cooperative Continuously Operating Reference Station (CORS).
The original station officially came online at 920 Country Club Road in Eugene, Oregon on January 1, 2001 and the station was designated with ID "OBEC" (see below for new designation) for OBEC Consulting Engineers. Code and carrier phase GPS data are generated and provided free of charge, in Receiver Independent Exchange (RINEX) format and Trimble proprietary DAT/T02 format. This data is used to obtain more accurate results from a variety of GPS projects.
On November 1, 2013, station "OBEC" was decommissioned in favor of our new site "OB3C". This decommission was due to a change in the antenna base mount. By replacing a Leica style quick release adapter to a SECO Adjustable Tilt Monument Mount (PN: 2072-31 A) the ARP was changed. This change required us to decommission the site due to NGS CORS Rules and Guidelines. In addition to the antenna mount we also upgraded the previous Trimble NetRS to a Trimble NetR9 GNSS multi-constellation receiver with a Trimble GNSS Choke Ring antenna with SCIGN short radome (TRM59800.00 SCIS). The new antenna is permanently mounted on a concrete and block building for stability.
Note that as of November 15, 2013 the position imbedded in data files was updated from autonomous to NAD_83 (2011) (2010.0000). The position was derived by Randy Oberg with the Oregon Real-time GPS Network (ORGN) using OPUS-Projects and 7 consecutive days of data. The position is available on our reference station coordinates page in addition to the final adjustment report.
