There is a race requirement which states that "Any boat which fails to transmit for more than 10 consecutive days will be disqualified."

While there are a number of ways of reporting position data back to Mission Control, from elaborate HF transmitters through to simple satellite position locators, we'll be using a Rock Block satellite modem. These devices can send byte sequences back to dry land via the Iridium satellite network. We will be sending four updates a day, of exactly 250 bytes each. Each message will include two or more payloads.

"Mother"

The main computer on board Nostromo in the film Alien was called Mother. It seems only right that we should call our main processor by the same name.

The Software...

By Dermot Tynan, over 8 years ago.

I've been asked recently, about the software platforms used on board Beoga Beag. This seems as good a time as any, to talk about the various layers. As mentioned previously, the lower layer is a custom board, running an ATmega8 Atmel processor. The software (Igor and Otto) is custom-written in C for the boat.
