ELECTRICAL POWER3 DieselGenerators113kW max

First winteringyear consumpt.:500000 kWh.

Cost for 1 year: 350 k€

1 kWh = 0,7 €(EdF: 0,06 €)


Necessary to install ecological power supplies


TELECOMMUNICATIONS

Present status:

•INMARSAT Connexion: 1€/min

(used for phone and data transfer, reliable)

•Data Transfer: 50 kbps only 3 times per day for e-mails down and up load and a few scientific data transfer. (1 MB = 3mn30 = 24€)

•IRIDIUM Connexion: low quality

Future evolution: 256 kbps permanently (Intelsat, Panamsat solutions)



LOCAL NETWORK

• Telephone everywhere

• 100 MB network between Concordia, summer camp et the labs.

• HUBs, wireless 54 MB


WORKING CONDITIONS

• Altitude + low temperature tiredness, difficulty to concentrate.At Dôme C, problems are much more difficult to deal with, so do everything possible to prevent them.

• Local assistance + hot line very limited Winterers requirements:• autonomy• large technical abilities• very deep knowledge of the instrument(s)• mental strength

• Federal Express does not serve Dôme C yet Bring enoughspares with you.
