ASTI Ground Receiving Station Antenna capped with Radome

Radome Installation for the DOST-ASTI Ground Receiving Station's (GRS) 3.7m Transceiver Antenna.

Completed at 12:30, 7 December 2018 PHT, the satellite antenna atop the DOST-ASTI building, Diliman, Quezon City, is now contained inside a 7.5m Radome – a special spherical structure enclosing the antenna from physical forces while still allowing reception of satellite signals.

Established under the Philippine Earth Data Resource and Observation (PEDRO) Center R&D Project, DOST-ASTI’s 3.7m transceiver antenna has been in constant operation since 2016 December. Since then, it has been receiving satellite data from DIWATA-1, and now DIWATA-2, alongside other supported foreign satellites. The Radome, weighing at approximately 1.5 tons, can withstand temperatures up to 80°C, wind speed of up to 320km/hr, and rainfall at 100mm/hr for 1 hour, thereby prolonging the effective lifespan of the antenna.

The Philippine Earth Data Resource and Observation (PEDRO) Center established a satellite Ground Receiving Station (GRS) facility in DOST-ASTI with direct access to a broad range of optical (high-resolution, multispectral) and radar (cloud-penetrating, day-night-imaging) satellite data. PEDRO is complementary to the Philippine Microsatellite (PHL-MICROSAT) Program, where ASTI is one of the main proponents. The PEDRO GRS facility receives daily imagery and data from the microsatellite, DIWATA-1 and DIWATA-2, which performs several applications based on its mission that includes environmental monitoring and disaster mitigation.
