New satellite data receiving station opens in Davao city

The Department of Science and Technology (DOST) is also gearing up for the future.

Just a week ago the DOST has launched a new satellite data receiving station in Davao city.

The facility will be the “largest tracking antenna in the country so far, will receive satellite data that may be used in pre- and post-disaster monitoring, among other scientific research and operational activities.”

The new station is expected to provide additional capacity and redundancy to the first station launched three years ago at the DOST-Advanced Science and Technology Institute (ASTI) in Quezon City. 

The GRS, which is part of the Philippine Earth Data Resource and Observation (PEDRO) Center, serves as the tracking antenna for earth observation satellites. 

The PEDRO Center receives images from various earth-observation satellites, including the country’s Diwata-1 and Diwata-2 microsatellites, as well as other supported foreign satellites.

The Davao station will serve as an auxiliary antenna for the PEDRO Center, enabling it to receive earth surface information even in cases of catastrophes and impending threats of disasters in Manila. 

“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,” DOST-ASTI said.

“Simply put, these ground facilities can upload commands and can download data captured by satellites deployed in space,” it added. 

The Davao station is home to a much larger antenna – 7.3 meter antenna compared to the Quezon city station with only a 3.7 meter, which will allow a satellite- tracking antenna 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,” said the DOST-ASTI. 
“The radome can withstand temperatures up to 80 degrees Celsius, wind speed of up to 320 kilometers per hour, and rainfall at 100 millimeters per hour for one hour, thereby prolonging the effective lifespan of the antennas,” it added.   
“The GRS facilities of the PEDRO Center are vital infrastructure for pre- and post-disaster monitoring that supports our disaster risk reduction agencies,” it added.
