> Dear Laser Stations, dear colleagues,
>
> Thanks a lot to all for your prompt reaction in tracking Envisat and for the
> reporting your delivered so far.
> This is highly appreciated and of utmost importance for us to understand and
> characterise the Envisat orbit and attitude.
>
> We are still sending regular TC toward Envisat but with no success so far.
> Investigation is on-going.
>
> I will therefore kindly ask to maintain (or even increasing if possible) the
> effort in tracking Envisat and to let us know more detailed information on
> the Envisat passes.
> Can you please report for each tracking pass:
> - In case no return, although no clouds present, laser station in nominal
> condition => Time of the pass
> - In case of partial returns, although no clouds present, etc.
> => Time of period where a return was expected
>
> This might not be a nominal procedure and a nominal type of information,
> however if you keep such type of logs that would be appreciated.
>
> Warm regards, Pierre Féménias
