Moxey, Lucas; Tucker, Compton; Sloan, Jim; Chadwick, John – Journal of Science Education and Technology, 2004
A low-cost (US$350) satellite receiving station was assembled and operated within a classroom environment in Gainesville (Florida) on October 2001 for acquiring satellite data directly from the Advanced Very High Resolution Radiometer (AVHRR) satellites. The simplicity of the satellite signal makes this source of real-time satellite data readily…
