Satellite Shorts from All Over [AMSAT]
- The NanoSail-D satellite mentioned in prior ANS reports was featured this week in a NASA web release: “This summer, NASA engineers will try to realize a dream older than the Space Age itself: the deployment of a working solar sail in Earth orbit. It is scheduled for launch on-board a SpaceX Falcon 1 rocket as early as July 29, 2008?. See:

The SDR transponder aboard SuitSat-2 is based on the High Performance Software Defined Radio “Odyssey” system.

The CMOS camera aboard Cute-1.7 + APD II is controlled by a PDA which also performs the JPEG format
conversion and compression prior to transmission via FM packet on the satellite's UHF downlink. [AMSAT]

Surveillance cameras on runway pass test [Singapore]
After a 15-month trial at Singapore Changi, a new surveillance system that detects foreign objects and debris on runways will be installed at Chicago O’Hare later this year.
Installed by aviation technology firm SITA, the system uses a series of cameras installed along the runway to constantly capture surface images. The images are sent back to computers, allowing airport officials to verify the presence of a foreign object and determine whether to deploy a clean-up crew.
Traditionally, airports have relied on radar and manual inspection to detect foreign objects on runways.
Umar Khan of SITA says testing at Changi showed that it was able to detect objects less than an inch in size from 330 yards away. Changi is installing the system on two of its runways.
The 2000 Concorde crash in France was determined to have been caused by runway debris. A metal strip on the runway caused a tire to explode on takeoff, damaging the supersonic jet.
