iTrek Z1 GPS datalogger precision test
Sun, 2008-04-06 13:58 — nicoThe iTrek Z1 datalogger GPS with a solar panel is based on the MTK chipset produced beginning in Q1 2007. I brought this GPS data logger, along with three other GPS units, on an ethnoarchaeological research project in Peru in 2007 where we travelled with a traditional salt-bearing caravan for 14 days, and I gathered 9 days of data logging with the iTrek Z1. I conducted this test to evaluate the precision of the GPS in the southern hemiphere where there is no WAAS.

There are two main groups of GPS units used by field scientists: "recreational" and "mapping" grade GPS units. This post is about using Recreational GPS units for fieldwork in 2006.
