Real-Time Construction Staking
Surveying has changed from a profession in which one learned skills on the job and could even become licensed without a degree. Now firms are turning to high tech equipment using geographic...

Rapid Slope Monitoring
Use of inexpensive coaxial cable rather than inclinometers has cut the cost of monitoring slope movement at seven potential landslide sites in California. The method involved is called...

Translating Images from Raster to Vector Format for Environmental Assessment

Using a Small Satellite Bus As a Dedicated Platform for On-Orbit CSI Experiments
Control-Structure Integration (CSI) technology will be needed for the success of many future space missions, however, this technology will not be seriously considered for use by program...

A Conceptual Study of A Solar Power Satellite Using Centrifugal Force
We studied the self deployable Solar Power Satellite (SPS) using centrifugal force in order to explore ways in reducing construction costs. We designed a 340 kW SPS, and studied the unfolding...

Use of GPS for Tethered Satellite Position Determination
This paper provides a description of the potential application of GPS to determine the position of a tethered satellite with respect to the Space Shuttle. Relative positioning is performed...

Overview of Space Environmental Effects
The natural environment for low Earth orbit subjects satellites to various forms of damage, ranging from particulate impacts, ultraviolet light, atomic oxygen erosion and charged particle...

TOPAZ II System Description
The TOPAZ II single-cell thermionic space reactor power system was designed, built and tested by the former Soviet Union (Russia). It has been purchased by the United States (U.S.) for...

Solar Power Satellites
Earth's fossil fuel supply is dropping quickly. A new power source must be developed to save the remaining fuel and control pollution output. Solar power satellites are large satellites...

Space Stations Past, Present, and Future
The paper discusses the evolution, present state and future of space stations. Man's interest in the stars led to many inventions and the ultimate launching of the Russian satellite Sputnik,...

An Inflatable Antenna for Space-Based Low-Frequency Radio Astronomy
Antennas for a low-frequency orbiting radio telescope must have minimal problems in deployment, a directional beam, and a wide-angle scanning capability. Inflatable antennas with deposited...

Low Frequency Radio Astronomy from Earth or Lunar Orbit
Acquiring data at low frequencies is complicated by the fact that the ionosphere strongly disturbs the data, especially for high-resolution ground-based telescopes. The most viable observational...

The History and Present Status of Microwave Aircraft
The history of microwave-powered aircraft is reviewed from the point of view of interaction between the technology of beamed microwave power transmission and the applications for it. the...
