  1. Use of DAB Satellite for Addressable Alert Delivery Presentation at the Training Workshop on Disaster Risk Management in the Information Age by S.Rangarajan, WorldSpace at the World Bank October 8-9, 2008

  2. Wide Coverage Transmission to Audio Receivers In Service In Service Emergency Situations Village Classroom Individual WorldSpace: a snapshot Solar Powered Creating a Digital Library Selectively Addressable Automatic Alerts

  3. Applications of a DAB satellite: e.g., WorldSpace Data Multicasting • File Broadcast Services • Provides for the distribution of files to all recipients of a CUG. • Audio • Direct delivery of multiple channels of Pre recorded/ Live Audio to compact receivers Data stream transmission Provides the distribution of data streams to all recipients of a CUG. Combined Live Audio & Slide Show (CLASS) Synchronous, live instructor lead classroom. Distribution of Emergency Alert Messages Selectively addressable, secure, reliable and instantaneous.

  4. Alert Delivery through WorldSpace • Covers more than 100 countries with one secure uplink • Can be addressed by country, group, tier or even the current location of the receiver • Delivered with a latency of less than 10 seconds • Automatically triggers a siren/alarm whether or not the receiver in use • Displays text and automatically switches to audio information in local language(s) • Caters to diverse requirements/infrastructure ranging from a sophisticated weather office to a fisherman out at sea • Goes beyond conventional modes of communication and supplements/complements other technologies • Survives most hazardous conditions & power failures • Re-used for the daily requirements of the community (entertainment, agriculture, health, training..)

  5. Alert Delivery- How it works Event Sensors Radio or Land lines WorldSpace Satellite Uplink CAP format To AREAReceivers Warning Centers Satellite Coverage Area CAP formatting, Audio in Multiple Languages

  6. Alert Delivery-Custom Solutions Service Options • Text Only • Text with Siren • Text with Shared Audio • Text with Dedicated Audio • Alert plus Data Delivery Terminal Options (AREA- Addressable Radio for Emergency Alerts) • AREA-C Audio Alerts for Community Deployment • AREA-M Alerts for the Mobile User • AREA-A Audio and Data Alerts for the Computer-connected User

  7. AREA-C • AREA-C is ideal for community deployment • Immune to loss of main power at the time of the alert • Battery can be recharged by main or solar power • External siren controlled by a relay that is closed by the WorldSpace satellite signal • Option to connect to Public Address system • Additional box displays all alert parameters • Radio plays the remotely selected audio channel that carries authentic information

  8. AREA-M • AREA-M is meant for mobile users • A GPS receiver is connected through the external box • The box displays the current location of the receiver before the onset of alert • The alert is triggered only if the current location of the receiver is within the alert zone defined by the sender • Can be powered by the vehicle power supply without using the external battery • Ideal for travelers on land and sea

  9. AREA-A • AREA-A is a configuration that connects to the USB port of a computer • Supports all audio and data services of WorldSpace • Onset of alert is indicated by a computer generated siren • Displays all the alert parameters (mandatory & optional) • Can support audio/data download, even during the alert state • Can support text-to-speech for the alert description

  10. Alert Delivery-Typical Timeline Actions at the Alerting end Time = 5:35 pm • Tsunami warning received from NOAA 5:36 pm (1 minute elapsed) • Confirm the message • Type out Alert parameters in the CAP format using the WorldSpace GUI • Record a short audio message in the local language • Convert audio file to the required format and FTP to WorldSpace server 5:40 pm (5 minutes elapsed) • Issue the Alert through WorldSpace text channel • Insert audio in the alert audio channel At the Receive point Time = 5:41 pm ( 6 minutes elapsed) • AREA –C sounds a siren, displays alert parameters and switches the audio to the alert audio messaging channel whether or not the radio was being used at this time • AREA-M responds to this alert signal only if its current position is inside the alert zone. It also displays the text and plays out the alert audio channel • AREA-A uses the computer to provide a more comprehensive display of the alert parameters, plays the alert audio on the computer and optionally generates a siren sound on the computer.

  11. The Implementation Challenge • New Technology • Alert Delivery is the responsibility of a government agency and usually that agency has no role or budget for social development • Need for coordination among Ministries • A comparatively large one-time investment if it has to scale up to its full potential • Need owners for the activities at non-alert times (which is hopefully most of the time!) • Continued training of personnel at the hub as well as in the communities • Sustainability and upkeep of the system

  12. Model in Indonesia-PPP Satellite Capacity Commercials Alert Content

  14. Model in Sri Lanka

  16. Model in Bangladesh

  18. In Summary • The Government Agency responsible for Alert Delivery needs local partners • These partners can be NGO’s, Private sector or other national organizations (Each country has to choose a model that best suits it) • Non-alert time usage of the system vital not only for the economics, but for the local acceptance & up keep of the system • If implemented in a large scale, across multiple projects and over a long duration, these solutions are cost-effective • Need to bring in regional cooperation and inter-operability • Important to adopt CAP and establish a Transmission Hub for all hazards, all media and all locations • One point generation of the alert and multi point multiple media dissemination is reliable, scalable, sustainable and cost effective.
