A personal locator beacon system has a personal locator beacon and a biometrics monitor. The personal locator beacon includes a first microprocessor, a first global positioning subsystem coupled to the first microprocessor, a first low energy transceiver coupled to the first microprocessor, and a first low energy antennae coupled to the first low energy transceiver. The biometrics monitor includes a second microprocessor, a second low energy transceiver coupled to the second microprocessor, a second low energy antennae coupled to the second low energy transceiver, and one or more nanosensors.
