The Tiny Satellite Conference, held last week in Logan Utah, is the premier conference for the small satellite technology community (Proceedings).
Their twenty-fifth conference attracted massive name speakers including Bruce Carlson, Director of the NRO, Robert Gold, MESSENGER Science Payload Manager for Johns Hopkins, and Robert Braun, Chief Technologist, NASA.
The CubeSat Project (list of satellites) was began by a partnership in between the California Polytechnique University in San Luis Obispo and Stanford University in Palo Alto. It has considering that grown to turn out to be an international partnership of more than 40 institutes that are creating picosatellites.
Cubesats are built by colleges and universities to discover concepts. The cost is low – about the cost of a new auto – acquiring them into space is the trick.
A regular CubeSat is a 10 cm cube with a mass of up to 1 kg, although two and three cube satellites have been built. Developers benefit from the sharing of data inside the community. Resources are normally shared between developers and by attending CubeSat workshops.
Technical sessions at the Tiny Satellite Conference included nanosatellite-based astronomy missions, FPGA-Based Processors for CubeSats, Compact Hyperspectrals, and little SAR (Synthetic Aperture Radar) satellites
Vulcan Wireless has flown a CubeSat radio data link, controlled by the Nexus 1 Android telephone. The user is able to send control messages from the ground to the space vehicle from an Android application.
Their CSR-SDR (CubeSatellite Software Defined Radio) (pdf) successfully flew into space on 5/4/2010 from Space Port America in New Mexico on an Up AeroSpace Spaceloft XL.
The University of Surrey has developed STRaND-1, an Android-powered nanosatellite that will be launched into orbit in early 2012. Surrey Satellite has built and launched 34 tiny satellites given that becoming founded in 1981.
With LTE-Advanced supporting affordable radio relays and Software program Defined Radio, the possibilities for tiny satellite swarms to do helpful work seem to be multiplying. Acquiring to space (inexpensively) is the difficult portion.
At the Oregon International Airshow this weekend I chatted with Dr. Doug Donkel of Premier Space Systems whose Nanolaunch Project hopes to make launching nanosats like Cubesat a lot less expensive and more responsive.
They work with Portland State Aerospace Society to integrate the control systems, electrical components, telemetry and camera systems.
Spath Engineering certifies the rocket motor by way of static testing, engineers the aircraft-rocket interface, and launch control technique.
Space Engineering Group – SPG, supplies the rocket motor and oversees the rocket operation. SPG is 1 of the world’s leaders in hybrid rocket propulsion field and has created a distinctive high overall performance hybrid rocket technology. The non-toxic, effortlessly handled fuel is produced from a substance similar to what is utilized in common candles – paraffine.
A Mig-21 jet takes the rocket and its payload into near space. It’s a far less costly way to go than one thing like Orbital Sciences Pegasus, slung under a Lockheed L-1011.
In other news, Seven medium to little satellites from four continents were launched into orbit Wednesday on best of a Dnepr rocket. Two spacecraft manufactured by Surrey Satellite for Nigeria were successfully contacted right after the launch by way of ground stations in Nigeria and the United Kingdom, according to SSTL. NigeriaSat 2 weighed roughly 600 pounds at launch, and will give high resolution maps of Nigerian territory.
The University of Rome’s EduSat microsatellite and two U.S.-built AprizeSat asset tracking satellites, each weighing about 25 pounds, also rode the Dnepr launcher into space Wednesday. ExactEarth will take ownership of the two AprizeSat spacecraft following profitable completion of in-orbit testing (pdf).
Space-based AIS is becoming a extremely competitive marketplace, with Orbcomm and Com Dev of Canada, via its exactEarth subsidiary, racing to put AIS capacity in orbit.
ORBCOMM was the 1st commercial satellite network with Automatic Identification Method, a shipboard system that transmits a vessel’s identification, position and heading. ORBCOMM utilizes their own low-Earth-orbit satellites to provide tracking, monitoring and messaging capabilities. With the failure of all six Fast Launch satellites, nevertheless, Orbcomm will not be able to resume AIS service until the next-generation satellites launch.
Orbcomm-1 satellites make up most of the existing Orbcomm constellation of about 35 minisatellites. Their next generation will incorporate AIS radios.
ExactEarth claims to be the world’s leading Satellite-based vessel monitoring service. They successfully launched two advanced AIS satellites this week to extend its exactAIS constellation and increase capacity of its global vessel monitoring service. Their COM DEV core technologies is said to enable ExactEarth to filter out all but a very particular VHF portion of the signals devoted to AIS. To attain global AIS coverage with a latency of about 10 minutes about 30 satellites are needed.
COM DEV has calculated that only 3 satellites are required to supply a six hour “revisit time”. According to CEO John Keating, “If you put 3 satellites in polar orbits that takes 100 minutes to total, 120 degrees apart from 1 one more, then [due to the earth’s rotation] you can see any point on earth within six hours – you may possibly be over the poles when each and every 30 minutes, but you are everywhere over the equator as soon as every six hours.”
ExactEarth AIS satellites pass over Norway’s Svalbard Earth Station each 90 to 100 minutes. AIS tracks vessel movements in near actual-time and updates each two minutes or so when near shore stations.
The International Space Station (ISS) represents an ideal platform for testing AIS receivers due to its orbit: its 400 km altitude is low sufficient to give a high probability of ship detection and it also passes across a lot of of the globe’s most densely populated shipping lanes. A tiny, polar-orbiting satellite, by contrast, can see all of the earth.
Norway’s NORAIS and Luxembourg’s LUXAIS have been utilised on the ISS. They had been connected to an AIS antenna constructed by the ARISS (Amateur Radio on the International Space Station) community.
