Using radio relay for the communication
The aim of this experiment is to test the use of a communication relay while on EVA. To do so, the team in EVA will place a relay on a good spot so they can use the radio at a greater distance. The relay is composed of two two-way handheld radios, and a repeater. This configuration is very cheap and power efficient, since the radios can work during the whole duration of the EVA. The relay will be placed at the top of a mast. The mast will have to be transported by the team and positioned while on eva. Upon return from an EVA, the team will have to unmount the relay and take it back to the base. On “Mars” there is no such things as cellphones. On the MDRS base in the Utah desert the participants will only be provided with a While on “Mars” there is no such things as cellphones. On the MDRS base in the Utah desert the participants will only be provided with a radio. The problem is that when there is an obstacle such as a hill or a canyon, communication is easily lost. Also, the team can not go at a greater distance than the one the radio can cover. To improve communicaton, Bertrand will use a portable radio relay that the team will place when they go on a mission. The distance at which communication is possible will be improved.
