1/ CelesTrak is offline again as we work to send another 4,500+ IPs using code with HTTP_USER_AGENT: Deno/2.1.4 (variant; SupabaseEdgeRuntime/1.74.3) to the firewall.

 *WE NEED YOUR HELP* to find whoever wrote this code and get them to turn it off or CelesTrak will continue to be unusable.

Quick tech breakdown for the ERMINAZ mission: The satellites use SSDV to split JPEG images into robust packets. These are embedded directly into standardized CCSDS Transfer Frames using Virtual Channel ID 4 (VCID 4) for seamless decoding on Earth. Open Source! 🛸📡 #PocketQube #CubeSat #AMSAT

If you're wondering why you often can't get to CelesTrak lately, it is because we are dealing with a surge of users using software that blatantly violates our usage policy (celestrak.org/usage-policy...). We are working to clean up the mess, but they are making the site unusable for everyone.

Nouvelle version majeure : PREDICT v3.0.0 est disponible ! Compatibilité avec les nouveaux formats des éléments képlériens
C'est une annonce qui va réjouir la communauté des radioamateurs et des passionnés de poursuite satellite. John Magliacana (KD2BD) a officialisé via AMSAT-BB la sortie de PREDICT v3.0.0. Contrairement aux applications graphiques comme Gpredict , PREDICT reste fidèle à sa philosophie : une application en mode terminal, délibérément allégée, consommant un minimum de ressources, et nativement conçue pour le multi-utilisateur et l'automatisation réseau.
