    Following my report yesterday that Eutelsat W1 ( geo 10 degs east ) had 
    suffered some kind of failure , the operators have now put out a statement.
    
    I'm not quite sure what is meant by depointing.....apart from the fact that 
    everything went off for about nine hours....but until the full investigation 
    is completed it looks like  this is as much as we will get.
    
    
    W1 is  mainly used for news agency feeds , internet via satellite etc and 
    carries very little Direct to Home material. I begin to wonder if  this 
    would all have gone unnoticed had it not been for our monitoring of the 
    situation.
    
    As it is , the satellite is now up and running again and Eutelsat are no 
    doubt breathing a sigh of relief after what looks like an excellent recovery 
    !

    EUTELSAT STATEMENT ON W1 SATELLITE
    
    Paris, 11 August 2005
    
    Eutelsat confirmed that a depointing of its W1 satellite located in 
    geostationary orbit at 10 degrees East occurred during the day of 10 August 
    from 14.47 Paris time.
    
    
    During the nine hours following the identification of the anomaly acceptable 
    service was progressively resumed for the vast majority of users, and 
    optimum operational pointing of W1 was reestablished on 11 August at 
    approximately 01.00 Paris time. Nevertheless, during this period, and as a 
    precautionary measure, Eutelsat immediately proposed alternative satellite 
    solutions to clients who were technically in a position to operate on 
    another satellite of its fleet.
    
    
    The preliminary analysis of the investigation indicates that the incident 
    was related to a power subsystem anomaly. The consequence of this incident, 
    impacting on the power distribution within the satellite, has resulted 
    currently in two operational transponders being unavailable for service. A 
    technical investigation on this anomaly is continuing in collaboration with 
    the satellite's manufacturer, EADS Astrium.
