Yesterday I had the opportunity to meet Marianne Okal, who through her work at UNAVCO, builds gps systems to support field science work. UNAVCO maintains GPS stations in fixed locations around McMurdo that serve to calibrate roving GPS systems at field sites. Because GPS information from satellites can be subject to weather and electrical conditions, UNAVCO’s fixed base systems help to provide more accurate information by constantly comparing GPS readings at the fixed bases to their known locations, and then error correcting for all GPS systems in the area.

Marianne showed me some GPS systems she had been building for the field, and some visualizations of GPS data from a survey on a glacier shown here.
