(CLS America merged with Woods Hole Group at the beginning of 2018.) Woods Hole Group has offices in Texas, Maryland, Massachusetts, and a satellite office in California. We are also part of the CLS Group which is headquartered in Toulouse, France. The company was established in 1986, a fully-owned subsidiary of CLS. The company has its origin in the US-French Satellite Data Collection program called Argos, which is governed by a memorandum of understanding between US NOAA and CNES, The French Space Agency. Since 1986, we have been organized as an operational satellite data center, which collects, archives and disseminates data collected by satellite, including Argos and Iridium, to Governmental users: NOAA, DOD, US federal law enforcement agencies, national weather services, major universities and institutions. This page is managed by our satellite office in California as well as our office in Lanham, MD and is focused on our Environmental Monitoring business unit and more specifically our Satellite Services division. Argos is the main satellite tracking tool used by researchers to study animal behavior and migration. We monitor the locations of approximately 8,000 animals at any given time including birds, land animals, and marine megafauna.
