Lacrosse or Onyx is a series of terrestrial radar imaging reconnaissance satellites operated by the United States National Reconnaissance Office (NRO). While not officially confirmed by the NRO or the Government of the United States prior to 2008, there was widespread evidence pointing to its existence, including one NASA website. In July 2008, the NRO itself declassified the existence of its synthetic aperture radar (SAR) satellite constellation. Unit costs (including launch) in 1990 dollars are estimated to be in the range of US$0.5 to 1.0 billion.

  • Lacrosse (auch Onyx) ist die Bezeichnung für eine Serie militärischer Aufklärungssatelliten des National Reconnaissance Office (NRO) der USA. Die Satelliten verfügen über Synthetic Aperture Radar (SAR), ähnlich dem auf der zivilen Raumsonde Magellan eingesetzten System, um unabhängig von Tageszeit oder Bewölkung Aufnahmen zu gewinnen. Die Auflösung dieses SAR-Radars liegt bei 50 cm. Hersteller der Lacrosse-Onyx-Satelliten ist die US-Firma Lockheed Martin Astronautics in Colorado. (de)
  • Lacrosse atau Onyx adalah serangkaian satelit pencitraan pengintai radar terestrial yang dioperasikan oleh National Reconnaissance Office Amerika Serikat. Meskipun tidak secara resmi dikonfirmasi oleh NRO atau siapa pun di pemerintah AS, untuk waktu yang lama, dan ada bukti luas untuk mengkonfirmasi keberadaannya, termasuk salah satu situs NASA. Pada bulan Juli 2008, NRO itu sendiri diklasifikasikan keberadaan konstelasi satelit SAR mereka. (in)

  • Lacrosse ou Onyx é a designação de uma série de satélites de reconhecimento de imagens por radar, operados pelo National Reconnaissance Office (NRO) dos Estados Unidos. Apesar de não serem reconhecidos oficialmente pelo NRO antes de 2008, existiam muitas evidências apontando para a sua existência, incluindo um site da NASA. Em julho de 2008, o NRO liberou os documentos secretos sobre a existência desses satélites e seus radares de abertura sintética. (pt)

  • Lacrosse et Onyx sont les noms de code de satellites espions à imagerie radar du National Reconnaissance Office des États-Unis. Bien que ce programme ne soit pas officiellement confirmé par le NRO ou par l'administration américaine, son existence ne fait aucun doute. L'instrument imageur principal des satellites Lacrosse est un radar à synthèse d'ouverture, capable de « voir » à travers les nuages et, dans une certaine mesure, à travers le sol. Les premiers satellites renvoyaient leurs images via le réseau TDRSS (Tracking and Data Relay Satellite System) à la base terrestre de White Sands, au Nouveau-Mexique. Il semble que les satellites plus récents sont capables d'utiliser d'autres réseaux. (fr)
  • Lacrosse e Onyx sono i nomi in codice di satelliti spia dell'Ufficio Nazionale per la Ricognizione (NRO, National Reconnaissance Office) degli Stati Uniti. Anche se non è stata ammessa ufficialmente dall'NRO, l'esistenza di questi satelliti è confermata da numerose prove. I satelliti Lacrosse effettuano mappature tramite un sistema radar ad apertura sintetica (SAR, Synthetic Aperture Radar), in grado di "penetrare" (inferire dati) fino ad una certa profondità nel terreno; a questo fine sono stati però spediti nello spazio strumenti ancora più efficaci.
