Location: The antenna is located at the Linn County Health Services Building, 799 Long St., Sweet Home, Oregon.

Equipment: Linn County uses a Trimble NetR9 GPS receiver coupled with a Zephyr Geodetic 2 GNSS antenna.

Broadcast Real-Time Kinematic (RTK) signal @ 453.2750 MHz using Trimble Trimark 3, 12.5 W radio in CMR+ format @ 1 second intervals with a station index @ 1. Wireless Mode, TMII 4800 bps.

Status: The Oregon Department of Transportation Geometronics Unit computed the latitude, longitude, and ellipsoid height at the Antenna Reference Point (ARP) by processing and adjusting five days of data using the National Geodetic Survey’s Opus Projects software.  The position is referenced to NAD83(2011)epoch 2010.00.

Description: The station is a 2 inch galvanized iron pipe, 4 feet long; permanently attached to the east end of the building.

Elevation: The Orthometric height at the Antenna Reference Point is referenced to NAVD88 and was computed by applying the Geoid 12A geoid separation to the ellipsoid height.
