Distinguish Picosatellite Infobox Earth satellite name PicoSAT image File PICOSat9USAF.jpg 180px launch date September 30, 2001 launch vehicle Athena I launch site Kodiak Launch Complex , Kodiak, Alaska Kodiak, AK orbit reference orbit type orbit altitude orbit inclination 100.2 orbit repeat 100.7 min orbit swath orbit crossing PicoSAT , launched on September 30, 2001, is a real time tracking satellite. The name PICO combines the first letters of all four of its experiments see below . PICOSat series are designed for a minimum of one year of on orbit operations. Background The name Picosat was coined by Peter P. Vekinis and was used to describe a constellation of amateur radio satellite s, called the Picosat System, first analog, then digital, that would offer instant emergency communications, worldwide, using cheap amateur radio transceivers. The details were presented at AMSAT s conference in Orlando, Florida, in 1995 and in Tucson, Arizona, in 1996. History Early versions Tethered Picosats, Picosat 5, Picosat 6, Picosat 7, and Picosat 8 are hectogram mass satellites that were ejected from OPAL 2000 004C . The primary builders were by engineering students at Santa Clara University in California. They used off the shelf components and miniature batteries, for technology tests. The Tethered Picosats were a pair of Picosats tethered together by a short wire, was ejected on February 8, 2000, from a OPAL Launch System ref http ssdl.stanford.edu opal LaunchVehicle.html Stanford University Opal Launch Vehicle ref . Picosats 7 and 8 on launched on 11 February, and Picosats 5 and 6 launched on 12 February. Alternate common names were given by the investigators Picosats 7 and 8 are the Thelma and Louise pair and Picosats 5 and 6 are the JAK and Stensat pair. The Tethered Picosats were functional for a short time after ejection, communicating with each other by microwatt radio transmitters. There was no indication if the Picosats 5, 6, 7,and 8 were operational at the time of ... more details
