Record number: 2, Textual support number: 1 OBS

The thermal control subsystem is a key system on which the successful performance of the spacecraft ultimately depends. Electronics equipment must operate within a relatively narrow temperature band if proper functioning is to be achieved and thermal failure avoided. This operating temperature range must be maintained in a vehicle that will be exposed to extreme temperature gradients. Heat generated internally must also be managed. Typically, satellites will spin to keep any part of the surface from getting too hot or cold.  3, record 2, English, - thermal%20control

Le sous-système de thermorégulation est un système essentiel dont dépend au bout du compte la performance du vaisseau spatial. L'équipement électronique doit fonctionner dans une gamme de températures relativement étroites pour obtenir de bons résultats et pour éviter les pannes. Cette fourchette de températures doit être conservée dans un véhicule qui sera exposé à des variations extrêmes de température. Il faut aussi gérer la température produite à l'intérieur du véhicule. De façon traditionnelle, les satellites tournent sur eux-mêmes pour éviter qu'une partie quelconque de leur surface ne devienne trop chaude ou trop froide.  5, record 2, French, - thermor%C3%A9gulation

Record number: 4, Textual support number: 1 CONT

The most significant difference between RADARSAT-2 and RADARSAT-1 payload technology is that RADARSAT-2 uses a fully-active phased array antenna, rather than the passive slotted waveguide antenna used by RADARSAT-1. Fully-active phased arrays offer a number of very significant benefits over passive antenna, but they also add great complexity.... The phased array is made up of 512 individual radiating elements, organized into 16 columns(picture below shows a single column) along the 15-metre antenna length, each with 32 rows across the 1. 5-metre width. The phase shifters and amplitude control are built into the Transmit/Receive(T/R) modules, which feed the radiating elements. Each column has a computer that controls the 32 T/R module settings and these 16 computers are all linked to another computer(in the spacecraft bus) that orchestrates the overall antenna behaviour.  5, record 4, English, - active%2Dphased%20array%20antenna
