This work analyses the formation factors and elimination methods for both the star sensor’s error and the angles error between the star sensor’s optical axis and the earth observation camera’s optical axis. Based on that, to improve the low attitude stability and long calibration time necessary of current satellite cameras, a method is then proposed for real-time on-orbit calibration of the angles between star sensor’s optical axis and the earth observation camera’s optical axis based on the principle of auto-collimation.

This seismometer is a Very Broad Band seismometer to measure the Martian seismic activity. Sodern provides an inverted mechanical pendulum, called VBB pendulum, the movement of which being detected thanks to very accurate capacitive sensors. Three similar VBB axes are incorporated in the same package; the package is a sphere under vacuum to allow the best quality factor of the pendulum. Severe constraints of mass as far as hard environmental conditions have required a very thorough optimisation of the design. Breadboards have been manufactured and tested. They allow demonstrating the capability of the sphere to be embarked with the SEIS instrument onboard the NASA/JPL INSIGHT mission. This paper describes the architecture of the VBB and the Sphere and gives the performances as measured on ground and expected on Mars.

  • EARTH OBSERVATION SYMPOSIUM (B1) Earth Observation Sensors and Technology (3) Author: Mr. Roland Le Goff Sodern, France, Roland
    67th International Astronautical Congress 2016 Paper ID: 34229 EARTH OBSERVATION SYMPOSIUM (B1) Earth Observation Sensors and Technology (3) Author: Mr. Roland Le Goff Sodern, France, roland.legoff@sodern.fr Mr. Guilhem Dubroca Sodern, France, [email protected] Mr. Didier Majcherczak Sodern, France, [email protected] Mr. Didier Loiseaux Sodern, France, [email protected] Mr. Martin Bauer Airbus DS GmbH, Germany, [email protected] Mr. Volker Kirschner European Space Agency (ESA), The Netherlands, [email protected] DESIGN OF SENTINEL-5 UV2VIS SPECTROMETER OPTIC Abstract The Sentinel-5 instrument, part of the joint ESA/European Union Earth observation programme COPERNICUS, is built by Airbus Defence Space GmbH. It is an assembly of Imaging spectrometers covering multiple spectral bands from 270nm to 2400nm. Sodern is developing the optics of the UV2VIS spectrometer (UV2VIS SO). It is part of the UV2VIS spectrometer, linking the slit - attached to the telescope - to the CCD array. It operates from 300nm to 500nm. This paper gives an overview of the design rules and few critical aspects of performances identified by Sodern during the phase B, thanks to the strong heritage in the design and manufacturing of state- of-the-art optical sub-assemblies of Imaging spectrometers, with programmes such as MERIS (on-board ESA ENVISAT satellite) and the Camera Optical Sub-Assembly (COSA) on-board Sentinel-3 Ocean and Land Colour Imager (OLCI). The following aspects have been investigated and will be discussed: implementation of a refractive optical prescription based on a grism (prism plus transmission grating) and use of iso-static mounts with epoxy bonding in order to overcome relatively large CTE mismatch between refractive lenses substrates, silica and CaF2, and titanium structure.

  • Using Infrared Based Relative Navigation for Active Debris Removal
    USING INFRARED BASED RELATIVE NAVIGATION FOR ACTIVE DEBRIS REMOVAL Ozg¨ un¨ Yılmaz(1), Nabil Aouf(1), Laurent Majewski(2), Manuel Sanchez-Gestido(3), Guillermo Ortega(3) (1) Cranfield University, Shrivenham United Kingdom, fo.yilmaz,n.aoufg@cranfield.ac.uk (2) SODERN, Limeil-Brevannes France, Email: [email protected] (3) European Space Agency, Noordwijk The Netherlands, Email: [email protected] ABSTRACT A debris-free space environment is becoming a necessity for current and future missions and ac- tivities planned in the coming years. The only means of sustaining the orbital environment at a safe level for strategic orbits (in particular Sun Synchronous Orbits, SSO) in the long term is by carrying out Active Debris Removal (ADR) at the rate of a few removals per year. Infrared (IR) technology has been used for a long time in Earth Observations but its use for navigation and guidance has not been subject of research and technology development so far in Europe. The ATV-5 LIRIS experiment in 2014 carrying a Commercial-of-The-Shelf (COTS) infrared sensor was a first step in de-risking the use of IR technology for objects detection in space. In this context, Cranfield University, SODERN and ESA are collaborating on a research to investigate the potential of IR-based relative navigation for debris removal systems. This paper reports the findings and developments in this field till date and the contributions from the three partners in this research. 1 INTRODUCTION The precise relative navigation of a chaser spacecraft towards a dead satellite is one of the most dif- ficult tasks to accomplish within an ADR mission, due to the fact that target is uncooperative and in general in an unknown state [1].
