Data Reduction and Compression
- Roberto Camarero (ESA)
In this paper, we describe compression strategies currently under consideration in the H2020 EO-ALERT project. In particular, we investigate the performance of the CCSDS-123.0-B Issue 2 standard for image compression when used for the purpose of compression of synthetic aperture radar (SAR) raw data onboard of satellite systems.
The task of compressing SAR raw data presents a great challenge...
Earth observation (EO) data delivered by remote sensing satellites provides a basic service to society, with great benefits to the civilian. The data is nowadays ubiquitously used throughout society for a range of diverse applications, such as environment and resource monitoring, emergency management and civilian security. Over the past 50 years, the EO data chain that has been mastered...
Compression of multispectral and hyperspectral images is becoming more and more important as the spatial and spectral resolution of the instruments keep increasing. New techniques are therefore needed to cope with such high data rates. Recently, significant work has been devoted to methods based on predictive coding for onboard compression of hyperspectral images. This is supported by the new...
The most important challenge underpinning the transition to next generation of Space missions design is the discrepancy between the dramatic increases in observation rate and the marginal increase in downlink capacity, enforcing the shift from the traditional “acquire-compress-transmit” paradigm to highly efficient intelligent on-board processing of observations, minimizing downlink...
This paper introduces the analyses performed while developing a hyperspectral compression technique based on a novel solution able to satisfy the needs, and thus to candidate for, the next generation hyperspectral missions (e.g. the forthcoming Sentinel-10).
The proposed solution leverages the achievements obtained by the OP3C (On-board Processing for Compression and Clouds Classification)...
CHEOPS, the Characterizing Exoplanets Satellite, is a Swiss-led ESA-S mission to be launched in early 2019. It is an optical space telescope in a polar orbit to carry out ultra-high precision photometry providing radii of transiting exoplanets.
The University of Vienna (UVIE) together with PnP Software have developed the Instrument Flight Software (IFSW). This software controls the instrument...
