Desert rescue system / Social impact

Supervisor's desert project made us realize that there are more and more official and private exploring teams in the desert. In addition, the desert is also the way for many refugees to flee war and other disasters.
However, the desert environment is poor and people are at risk of water shortage and getting lost. The existing search and rescue system is single and mainly relies on private satellite phone and helicopters, which is unaffordable to most ordinary people, especially the refugees. In order to save lives of those trapped people in desert, we designed the Desert Trapped Help System.
