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 satellites, 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 an OPAL Launch System.[1] 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 ejection into orbit. USSPACECOM's Picosat numbers extending to eight is erroneous. There were only six Picosats on board the OPAL, with possibly one or two still on the ground, with tests to communicate with the orbiters. The tests were managed by the Defense Advanced Research Project Agency (DARPA).[2]

Current version

The current Picosat 9 is a British-built (US DOD-funded) microsatellite (67 kg) to test electronic components/systems in space conditions. Oboard this model carries four test payloads: Polymer Battery Experiment (PBEX), Ionospheric Occultation Experiment (IOX), Coherent Electromagnetic Radio Tomography (CERTO) and On Orbit Mission Control (OOMC) an ultra-quiet platform (OPPEX). PICOSat flies in a 800 km circular orbit with a 67 degree inclination. PICOSat uses a gravity gradient boom for stabilization. The body mounted solar panels produce an average on orbit power of 22 W. The Ultra-Quiet Platform (UQP), developed by the US Air Force Research Lab, aims to provide a 10:1 reduction in vibration isolation over a 100 Hz bandwidth between the spacecraft bus and a science payload.[3]
