MILESTONE UNFOLDS: Phl largest tracking antenna for earth observation satellites operates in Davao – PRESS RELEASE
Davao City, Ph -- Three years after the first Ground Receiving Station (GRS) of the Philippine Earth Data Resource and Observation (PEDRO) Center was set up at the DOST-Advanced Science and Technology Institute (DOST-ASTI) office in Quezon City, another milestone unfolds as the soft-launching of the second GRS was held in Davao City this weekend – unveiling the Philippine’s largest tracking antenna for earth observation (EO) satellites to date.
Attended by Department of Science and Technology officials headed by Secretary Fortunato dela Peña, the soft launch was held on 30 June 2019 at the Civil Aviation Authority Philippines (CAAP) Transmitter Facility in Davao City.
Now fully operational, the Davao GRS (D-GRS) provides additional capacity and redundancy to the functions of the PEDRO Center in Quezon City. The PEDRO Center, since its start of operation, has been receiving satellite-captured images from various earth-observation satellites, including the Philippines’ very own Diwata-1 and Diwata-2 microsatellites, alongside other supported foreign satellites.
The establishment of the D-GRS serves as an auxiliary antenna for the PEDRO Center, which means that in cases of catastrophes and impending threats of disasters in Manila, the PEDRO Center can still receive earth surface information.
Designed to communicate with earth observation satellites by receiving, processing, and distributing space-borne imagery, these ground receiving stations also have direct access to a broad range of optical (high-resolution, multispectral) and synthetic aperture radar (cloud-penetrating, day-night-imaging) satellite data. Simply put, these ground facilities can upload commands and can download data captured by satellites deployed in space.
For the time being, the D-GRS is remotely-operated and is used for initial tests such as the download of MODIS data from Terra and Aqua satellites. Compared to the PEDRO Center with only 3.7 meters, the D-GRS has a 7.3-meter satellite-tracking antenna which will allow more efficient download of images at a higher bandwidth.
Both antennas are contained inside a radome, a special spherical structure enclosing the antennas from physical forces while still allowing reception of satellite signals. The radome can withstand temperatures up to 80°C, wind speed of up to 320km/hr, and rainfall at 100mm/hr for one (1) hour, thereby prolonging the effective lifespan of the antennas.
The direct reception of data from earth observation satellite images provides the PEDRO Center more capability in near real-time acquisition of information. With the ASTI and Davao GRS in full operation, the reception, processing, and satellite data storage cycle will open more opportunities to promote inclusive innovation, reaching more Filipino scientists and researchers in return.
The GRS facilities of the PEDRO Center are vital infrastructure for pre- and post-disaster monitoring that supports our Disaster Risk Reduction agencies.
The D-GRS was established with the support and cooperation of the DOST Region XI, the Civil Aviation Authority of the Philippines (CAAP), and the Department of Information and Communications Technology (DICT).
About the PEDRO Center
The PEDRO Center, located at and operated by the DOST-Advanced Science and Technology Institute, serves as the country’s main gateway in accessing geospatial data from earth observation satellites for various scientific research and operational activities. The Center complements the Stamina4Space (formerly PHL-MICROSAT Program), where DOST-ASTI is one of the main proponents. The PEDRO Center receives daily imagery and data from the Philippines’ DIWATA-1 and DIWATA-2 microsatellites, alongside other supported foreign satellites.
