Title: Use of DAB Satellite for Addressable Alert Delivery


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

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.

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..)

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

Alert Delivery-Typical Timeline
  • Actions at the Alerting end
  • Time 535 pm
  • Tsunami warning received from NOAA
  • 536 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
  • 540 pm (5 minutes elapsed)
  • Issue the Alert through WorldSpace text channel
  • Insert audio in the alert audio channel
  • At the Receive point
  • Time 541 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

In Summary
  • The Government Agency responsible for Alert
    Delivery needs local partners
  • These partners can be NGOs, 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.
