The University of Surrey, U.K. offers this website, providing "up to date information, resources, references and links for space researchers and enthusiasts on the internet." The Small Satellites Home Page (SSHP) focuses on small satellites and "the capabilities and advantages that small satellites can bring to existing and new applications." Small satellites had been the exclusive domain of scientific and amateur groups, but are now a viable alternative to large satellites given recent advances in microelectronics. The SSHP offers a history of small satellites, discusses why interest in small satellite missions has increased, and describes how the 'modern' satellites work. Visitors can also browse their listing of past, present and future small satellite missions or read a brief overview of "the anatomy of the small satellite." Other useful information posted online include tables of conversion constants, a list of acronyms and abbreviations, and an overview of orbits and orbital elements. Although a few of the links are not working, especially under the Special Lists section, the Technology link will lead you to data on various topics such as amateur satellites, military small sats, GPS navigation, and remote sensing.
