Decametric radio observation from Nancay decameter array. The Nancay Decameter Array (NDA) at the Station de Radioastronomie de Nancay (SRN) is a phased array of 144 "Teepee" helicoidal antenna, half of which being Right Handed (RH) polarized and the other half being Left Handed (LH) polarized. Four receivers are currently connected to the NDA, sampling data in spectral ranges within 5 to 80 MHz.
The SimDAL repository hosts numerical projects descriptions as standard XML documents following the Simulation Data Model serialization xsd. It allows clients to search (fulltext) for simulation projects or associated protocols of interest and get URIs towards other SimDAL components: SimDAL Search and SimDAL Data Access.
SkyBoT is a VO service which allows to seek and identify solar system objects (planet, satellites, asteroids, comets) in any field of view at a given epoch (cone-search method). It provides also a solar system object name resolver which convert the name or the designation of solar system objects into their celestial coordinates at a given epoch (resolver method). The SkyBoT service are available through a Web interface and a Web service (SOAP+WSDL+HTTP) which implements the IVOA Simple Cone-Search protocol.

VO-compliant publication of Schmidt survey SRC-J of the southern sky digitized with the MAMA microdensitometer at the Observatoire de Paris Image Analysis Centre (CAI).
The main activity at Nançay is the development and application of new radio techniques to fundamental research in astrophysics and astronomy. A number of instruments are operated on behalf of researchers in France and worldwide to conduct scientific programmes of observation of the Universe, including the nearby Earth-Space environment, the study of the Sun and the solar system, and the study of distant stars and galaxies in the Universe.
