This paper presents university-based design and development of a micro-satellite for the observation of a meteor shower from the low Earth orbit. The satellite will be launched as a piggy-back payload of a commercial rocket launcher, a few weeks before the 2001 or 2002 Leonid meteor maximum in which thousands of meteors are scientifically expected. The goal of the mission is to conduct the scie...

The Earth Resources Observation and Science (EROS) Center of U.S. Geological Survey EROS is currently managing and maintaining the world largest satellite images distribution system, which provides 24/7 free download service for researchers all over the globe in many areas such as Geology, Hydrology, Climate Modeling, and Earth Sciences. A large amount of geospatial data contained in satellite ...

The number of sensors for Earth environmental observation is growing. Several new sensors have been announced for the near future and several proposals for smart sensors have been proposed. In particular, distributed sensors, sensor network and sensor integration are being taken into account, and smart sensors, intelligent sensors, sensor’s autonomy, etc. is beginning to be used in future earth...

Why are today’s TV users able to receive different programs in their homes using different channels with a remote control? Why have lay users of satellite images not been able to receive satellite information directly for their applications until today? What is the future of earth observing satellite systems? These questions make us contemplate whether or not future Earth observing satellite sy...

Most earth observation satellites in their daily image processing routine operate using the “store and forward” mechanism; this mode of operation is not efficient due to the huge amount of data that has to be stored on-board the satellite (but cannot due to memory constraints). The Cape Peninsula University of Technology (CPUT) 3U CubeSat named ZACUBE-02 will perform the filtering and compressi...

Accuracy evaluation of cross calibration through band-to-band data comparison for visible and near infrared radiometers which onboard earth observation satellites is conducted. The conventional cross calibration for visible to near infrared radiometers onboard earth observation satellites is conducted through comparisons of band-to-band data of which spectral response functions are overlapped m...

Remotely sensed satellite data can provide spatial and temporal coverage for global environmental monitoring. Calibration and validation are very important for more accurate satellite products and can contribute to the detection of climate changes on earth. Calibration and validation of satellite products normally use both ground-based and satellite-based data, which have geospatial metainforma...

The development of Earth observation systems has changed the nature of survey and mapping products, as well as the methods for updating maps. Among optical satellite mapping methods, the multiline array stereo and agile stereo modes are the most common methods for acquiring stereo images. However, differences in temporal resolution and spatial coverage limit their application. In terms of this ...
