Celebrating ESA’s first small satellite with science success
Scientists and data users gathered at a special workshop to celebrate the end of PROBA-1’s CHRIS sensor and discuss the results of this overachieving mission.
New cross-calibration readies PROBA-1 data for climate research
While PROBA-1 has already exceeded expectations by suppling over 21 years of Earth observation hyperspectral data, recent cross-calibration activities are aiming to ensure the data will robustly serve long time-series research, even when the satellite ends operations.
Space helps monitor Earth’s changing biosphere
Earth’s biosphere is continually changing. Through its pioneering Earth observation missions, ESA is making critical contributions to monitor these changes and their impacts on Earth’s water and carbon cycles.
PROBA-1 - From technology demonstration to long-term Earth observation

PROBA-1 CHRIS Level 1A
CHRIS acquired a set of up to five images of each target during each acquisition sequence, these images were acquired when PROBA-1 was pointing at distinct angles with respect to the target. CHRIS Level 1A products (supplied in HDF data files, version 4.1r3) include five formal CHRIS imaging modes, classified as modes 1 to 5: Mode Name Swath Spectral Bands/Ground Resolution Mode 1 Aerosols 13 km 62 at 34 m (773 nm / 1036 nm) Mode 2 Water bands 13 km 18 at 18 m Mode 3 Land channels 13 km 18 at 18 m Mode 4 Chlorophyll band set 13 km 18 at 18 m Mode 5 Land channels 6.5 km 37 at 18 m Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service.
PROBA-1 CHRIS End of Mission Workshop
The PROBA-1 CHRIS End of Mission Workshop will take place from 18-19 January 2024 in Ghent, Belgium.
Topographic mapping from small satellites- a case study of CHRIS-PROBA data
This paper presents a study on the use of various empirical models for satellite orientation and terrain modelling using multidirectional CHRIS data, and evaluates the potential of small satellites with multidirectional viewing capabilities for topographic mapping.
A-comparison-of-superresolution-reconstruction-methods-for-multiangle-CHRIS-Proba-images.pdf
This paper presents the results of three superresolution methods applied to multiangular CHRIS/Proba data: three methods, namely non-uniform interpolation and de-convolution, iterative back-projection, and total variation are examined.
PROBA-1
PROBA-1 is a technology demonstration satellite that later became an operational Earth observation mission.
SPARC
ESA's SPectra bARrax Campaign (SPARC) activity was part of the preparatory study for a proposed ESA Earth Explorer mission called SPECTRA. The objective was to collect a CHRIS/PROBA reference dataset for SPECTRA-related studies.
Note on CHRIS Acquisition Procedure and Image Geometry
The aim of this document is to clarify the acquisition procedure CHRIS on-board the PROBA satellite. It provides a detailed description of the acquisition procedure and summarises the implications for the geometrical properties of the CHRIS images.
Hyperspectral Workshop 2010
Proceedings of the Hyperspectral Workshop 2010 held on 17-18 March 2010 in ESA-ESRIN, Frascati, Italy. This workshop was organised by the European Space Agency (ESA), the German Aerospace Center (DLR)/the German Research Center for Geosciences (GFZ) and the Italian Space Agency (ASI).
