"SATELLIFE Health Information Project" from the United States was one of the two winning projects at the 2002 Stockholm Challenge Award in the "Health" category. SATELLIFE uses multiple technologies - from satellites to modems - to connect health professionals to critical information in under-resourced areas. In rural Africa, manual health surveys are expensive, inadequate, inaccurate and slow. The project uses PDAs to collect timely public health data, return it to policy-makers and explore appropriate affordable technology for the environment. In a Ghanaian trial programme, 30 volunteers trained on the PDAs and completed over 2,400 surveys within five days. The data were analysed and the report delivered in six days instead of the usual four to six months.
