RAST installs IGATEs to expand the APRS network in Thailand

Thailand covers vast area of over five hundred thousand square kilometers. The northern part of the country is the mountainous area of the Thai highlands. The northeastern is on Khorat plateau. Along the roads of the northern and northeastern are stations of amateur radio. Most of them are VHF stations with repeaters equipped on them. The stations are important to provide contingency communication network especially during an emergency crisis. Some stations erect with high towers as tall as 160 m, and some are on high ground. Such stations can provide good receiving and transmitting radio signals. In order to provide data communication along the roads and area APRS internet gateways (IGATE) may be used, and, therefore, amateur radio can benefit from them.

Thailand also experienced with natural disaster for many times. The experiences have taught us that nothing better than “well-prepared” in advance. The IGATEs are, therefore, equipped with weather telemetry sensors including thermometer, humidity sensor, and altimeter. Such sensors are backing up the main national weather sensor-array.

As newly incidences in past few years, the atmospheric particulate matter with diameter of less than 2.5 micrometers (PM2.5) cover area of the country, it is RAST intension to include the PM2.5 sensors into the weather station on IGATEs in major cities. We expect to provide real time report of the weather quality and other weather parameters to the people.
