An overview of ESA's Third Party Missions programme

ESA’s Third Party Missions programme consists of almost 50 satellite missions, which are owned by organisations around the world. ESA has agreements with these organisations to acquire, process, and distribute data from their missions

Mission - Third Party Missions

PROBA-1

PROBA-1 is a technology demonstration satellite that later became an operational Earth observation mission.

Campaign

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.

Activity - Quality

EDAP

The ESA Earthnet Data Assessment Pilot (EDAP) project will perform assessments for various missions to ensure the delivered data is fit for purpose.

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.

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.

Correction-of-systematic-spatial-noise-in-push-broom-hyperspectral-sensors.pdf

We present a new technique that faces the problem of removing the spatiallycoherent noise known as vertical striping, usually found in images acquired by push-broom sensors.
