It also summarizes the functions of a VSAT hub, common VSAT applications for broadcasting and interactive services, benefits of VSAT networks, and basic VSAT installation steps.
VSAT is a small satellite terminal that transmits and receives data, video or voice via satellite. It uses a satellite-based WAN network with a central hub managing connections. VSAT dishes are typically 60cm to 3.8m wide. The system includes indoor and outdoor units, with the outdoor unit containing the dish antenna and the indoor unit providing an interface. A geostationary satellite revolves around the equator, relaying signals between earth stations, including a powerful hub station. VSAT networks allow point-to-point communication between users via the central hub and satellite.
The Emergency Managers Weather Information Network (EMWIN) is a system that disseminates weather data and alerts via satellite, radio, and internet. It provides rapid distribution of forecasts, graphics, imagery and other weather products. EMWIN collects data from various sources, prioritizes and packages it, then transmits the data stream to satellites and stations for rebroadcast to users including emergency managers, TV stations, pilots, and the public.
Using powerful and precise location technology that enhances the user experienceHitReach
The document discusses the evolution of location technology and its increasing importance. It summarizes that (1) early technologies like cell sector location had limited accuracy but helped build acceptance, (2) GPS and AGPS then allowed for street-level accuracy and mass adoption, and (3) current and future technologies are delivering even greater precision through techniques like WiFi, inertial sensing, and multi-GNSS support.
Similar to JASIL ICT Workshop for sharing WFD with Herders (20)
This document discusses using blockchain technology to create a decentralized and authenticated alert network. It proposes storing alert messages as "assets" on a blockchain, with publishers and subscribers as participants. Key transactions would include publishing, updating, deleting alerts, and acknowledging receipt. This could provide reliable attribution, integrity and help scale alerting beyond traditional systems by allowing many-to-many communication. However, some open questions remain around transaction speed and how well existing blockchain platforms model alert messaging requirements. The document also explores using the Interplanetary File System (IPFS) as an alternative to blockchains for an immutable and decentralized storage and distribution of alerts.

Common alerting protocol overview for pagasa 2016 [autosaved] [autosaved]Nuwan Waidyanatha
The document discusses the Common Alerting Protocol (CAP), which is a standard format for communicating hazard warnings across all media types. It was adopted by the World Meteorological Organization (WMO) for early warning systems. CAP allows communication of any hazard type to the public or designated groups. The document outlines CAP implementation in various countries and organizations, including the Philippines where CAP will be used to disseminate early warnings over the internet, smartphones, radio, and TV.
The document discusses the development and implementation of the Common Alerting Protocol (CAP) system in the Philippines for weather alert messaging. It describes how PAGASA, the Philippines' weather agency, has worked with partners like Google and WMO to develop and launch CAP. Key events included the initial launch in 2014 during Tropical Storm Ruby, training workshops, and ongoing work to expand CAP alerts and involve other agencies. The goal is to provide authoritative weather warnings to the public through CAP.
The document discusses Sahana, an open source disaster management software, and its alerting and messaging broker component called SAMBRO. It provides information on SAMBRO's functions, architecture, capabilities to interconnect with other systems, and how it can improve situational awareness during disasters. It then outlines Sahana's work with the Department of Meteorology and Hydrology in Myanmar to implement SAMBRO, including training workshops, tests, and exercises carried out to integrate it into Myanmar's warning systems and processes. The document concludes with recommendations to expand the use of SAMBRO's common alerting protocol (CAP) standard in Myanmar.
The document discusses a workshop on improving institutional responsiveness to coastal hazards through multi-agency situational awareness using Common Alerting Protocol (CAP)-enabled technology. It outlines a SWOT analysis of the CAP-enabled Sahana Broker identifying advantages, disadvantages, potential troubles, and opportunities for improvement. It also lists 6 discussion points focused on developing a national CAP implementation profile, collaborating with stakeholders, addressing policy issues, training personnel, and revisiting project plans and activities.
The document discusses the Common Alerting Protocol (CAP) standard for multi-agency alerting and situational awareness across all hazards. CAP allows alerts to be disseminated through multiple channels including TV, radio, websites and cell phones. It is an XML-based format managed by OASIS that is recommended by ITU-T and follows NSTC principles. The document provides an example of an automated standard message in CAP and demonstrates delivering alerts through various channels using a CAP simulator tool. Resources for further information on CAP are also listed.
This document discusses multi-agency situational awareness and alert implementation procedures. It outlines the typical vertical and horizontal integration of different agencies, and presents a management platform for collecting, transmitting, and controlling alert information. The document also discusses establishing a national Common Alerting Protocol (CAP) profile by defining the types of incidents covered, intended audiences, languages, geographic areas, and communication technologies used. It provides an example authority hierarchy register from the Philippines and information on the World Meteorological Organization's register of alerting authorities.
The document discusses using geographic information systems (GIS) and map layers to conduct risk assessments and improve situational awareness for multi-agency coastal hazard response. It outlines activities for a workshop including discussing data layers for risk assessment, emulating a sea level rise event, and an exercise where groups generate alert areas and consider hazard and census data, as well as emergency communications coverage. The goal is to adopt techniques from tools like Sahana CRMT to better prepare communities through mapping and information sharing.
Sahana is an open source disaster management software that was created in response to the 2004 Indian Ocean tsunami. It provides a platform for multi-agency coordination and situational awareness during disasters. Some key features include alerting, situation reporting, resource management, and social media integration. Sahana has been deployed for over 100 disasters worldwide and is used by organizations like the Red Cross, UN agencies, and various government agencies for emergency response coordination and planning. The Sahana Foundation is establishing a Center of Excellence at the Asian Institute of Technology in Thailand to support ongoing development and training.

Real-Time Biosurveillance Program Pilot - India & Sri LankaNuwan Waidyanatha
The Biosurv program was tailored for a range of functions. Its main objective program was the rapid detection and
notification of any possible health outbreak using cutting edge information processing technology. The
mHealthSurvey application takes a few seconds to enter each patient's disease information. This rich dataset is sent over the existing commercial GPRS channels to
a centralized database. With such techniques, the
incoming health data can be automatically monitored for unusual changes in the numbers of reported disease
cases. The same data is also used to characterize statistical relationships between all available combinations of reported genders, locations, ages, symptoms and signs, etc., even if the number of such combinations is
prohibitively large for humans to process. That enables epidemiologists to pin down a potential outbreak of, for
instance, a gastrointestinal disease among children living in the Southwestern suburbs of the city, before it
spreads to other areas or to other demographic groups. T-Cube Web Interface (TCWI) and its underlying disease
outbreak detection algorithms are capable of reducing time-intensive calculations involved in such analyses from
hours or days down to as quick as turning on a light switch.
