Automated Weather Observation System for Yogya

Adisucipto (or Adisutjipto) International Airport (IATA: JOG, ICAO: WARJ) is the main airport serving the Yogyakarta area on the island of Java, Indonesia. Adisucipto Airport is the third busiest airport in Java. In line with overall airport facilities upgrade, the airport authority took this opportunity to also improve and upgrade their Automated Weather Observation System. The existing system then was also due for change as it was based on proprietary and older generation of technologies. One key requirement was the the system must have the ability to process and display AWOS data in real-time to the concerned parties. To minimize project implementation risk, the project owner needed a system that is tested and proven in other airports.

Solution

After careful selection and evaluation of various solutions in the market, Techsense METairport suite of solutions has been chosen for Adisutjipto Airport. Captain Bakir of Adisutjipto Airport commented, "METairport has fully met that requirements and the most important factor of choosing METairport is its proven and test implementation in KLIA". What makes Techsense METairport the winning solution is the ability to acquire, process and display the various meteorological information in real time. Sensors installed along the runway are connected to their Techsense RTU and the data from the sensors are then streamed in real-time via the TCP/IP wireless connection to the Data Processing Unit located in the meteorological office of the airport.

Once the data is captured by the METairport software in DPU, the data from all the sensors are processed and generated into the relevant meteorological products for the airport usage. The meteorological products are distributed to the targeted users over the TCP/IP network and users can easily access these information using a standard web browser.

Benefits

Even though it is the first Web based AWOS implemented for Indonesia airports, the project was able to meet the tight deadline and completed successfully. This is largely due to the proven and tested METairport solution and also Techsense's experience in similar systems.

With the new system, the users can now access the various meteorological information in real-time which was unprecedented previously. Using web architecture in presenting the information also means more users can access to the system without requiring to install proprietary client-server software in their computers. With METairport fully running base on web technologies, there is no longer a real hindrance for other airports to access the information and hence enabling better sharing of information.
