CSIRO is developing new wireless technologies to locate, track, sense and communicate in areas where global positioning systems (GPS) do not work.

According to the scientific organisation, the terrestrial localisation systems are highly accurate, and can be used for a wide range of applications, from tracking workers in emergency situations to following sportspeople.

They will use radio frequency tracking technologies and aim to be cost-effective. Technically, the systems consist of a network of wireless nodes combined with sensors to monitor environmental variables and vital signs.

The technology will be developed in collaboration with Emergency Management Australia, Australian Radiation Protection and Nuclear Safety Agency, and the National Security Science and Technology Branch.

According to the Federal Attorney-General, the technology could be invaluable to Australian emergency service workers. It could help search for injured or lost people in hazardous situations.

The $1m collaborative contract will aim to pave the way for commercialisation of the technology starting in 2011.
