There are two precision GPS (Global Positioning System) sensor stations located on the Long Beach City College campus, one at LAC (Liberal Arts Campus) and the other at PCC (Pacific Coast Campus). They are part of the SCIGN (Southern California Integrated GPS Network), a large network of GPS monitoring stations, and are denoted by SCIGN as stations LBC1 and LBC2. Station LBC1 is located at LAC in front of the women's gym on the south side of Carson Street, near the pedestrian bridge, east of Clark Avenue. Station LBC2 is located at PCC.

What is GPS and how does it work?

The SCIGN website has information about SCIGN and a variety of GPS links.

By examining several years of data from the LBC1 station, or several years of data from the LBC2 station, you can see how the local ground is moving both horizontally and vertically over a period of several years.

Here are additional links to photos of the LBC1 station and photos of the LBC2 station.
