Now meteorologists needn't worry about not being able to make crucial announcements during a storm when power supply is cut off. The new cyclone warning dissemination system (CWDS) is being upgraded. It will work on direct-to-home (DTH) based equipment and can function for at least three days without needing to be charged.
The upgraded CWDS is a set-top box, which is commonly found in houses, modified by attaching an audio system to it. "We will be able to make announcements and receive audio signals through it," said G Gopal, a met department official. The modified set-top box would also have a battery back-up that can work on 12 volts, he said. "It will have two such batteries that ensure that it functions for 72 hours without requiring power," said Gopal.
The system developed by the Indian Space Research Organisation (ISRO) ensures that the DTH receiver gets only satellite signals and warnings from the local met department office, and works on a new bandwidth called ku-band. "The older receivers used to work on F band and X band — one to transmit signals and the other to receive," said Gopal.
