The groundstation runs on a Linux laptop - The airborne code has strong real time and high availability constraints that make the use of an OS no so desirable. Nevertheless we are aware that payload applications might benefit an OS - This is why our next generation board is designed as a gumstix (ARM9)daughterboard, where the autopilot runs in a pair of ARM7 microcontrollers and can be controlled by a gumstix/linux application. Here is a picture of the first prototype http://antoine.drouin.free.fr/lpc_board/arm_family/dsc00021.jpg http://antoine.drouin.free.fr/lpc_board/arm_family/dsc00020.jpg In the meantime and in order to offer commercial hardware support, we are porting the autopilot to the robostix board ( single avr mega128 gumstix daughter board ) http://gumstix.com/oscommerce-2.2ms2/catalog/product_info.php?cPath=31&products_id=142 And as two boards were not fun enough, we have also developed a smallish 'all-in-one' ARM7 board, nicknamed Tiny Here is a picture of the beast http://antoine.drouin.free.fr/lpc_board/arm_family/dsc00001.jpg Best regards Antoine
