Station:LFLO - Lane County Oregon Location Lane County uses a Leica GRX1200PRO GPS receiver coupled with a Leica AT504 IGS Type T Choke Ring L1/L2 antenna. The concrete pillar and braced aluminum mast is located on the south lawn of the Lane County Public Works Zone 5 Administration building at 1300 W. 20th St., Florence, OR. Station Status NOTICES: This position is based on a NGS solution in August 2006 using 19 days of data. Note:  The NAD83/91(Epoch 1995) position is based on local network control. This position should be shifted to fit recent GPS vectors using the NGS HTDP (Horizontal Time Dependent Program) in order to allow for tectonic plate movement.   Orthometric heights are NAVD88 based on Differential leveling. Position based on HARN sites and relative to existing Lane County Control monuments.

The files are zipped, with one zip file per hourly observation. If you do not have a zip utility we have provided links to a few vendors. Before downloading data files, get our File Guide for referral while selecting files. The guide explains the format of the files and the time frames. RINEX Data files Station Log
