National Earth Observation Satellite RASAT Enters Its 11th Year In Orbit

RASAT, the first domestic earth observation satellite of our country, designed and manufactured by the TÜBİTAK Space Technologies Research Institute (TÜBİTAK UZAY), has left behind its 11th year in orbit. Launched from Russia on 17 August 2011 and able to take images from all over the world without any limitations, RASAT weighs 93 kg and can circumnavigate the world in 98 minutes.

Images taken at 7,5 m black and white (panchromatic) and 15 m multi-band spatial resolution (pushbroom); It is used in cartography, disaster monitoring, agriculture, environment, urbanism and planning studies. The dimensions of each frame image of RASAT are 30 km x 30 km, and strip images up to 960 km long can be taken.

With RASAT passing over our country 4 times a day; Many high-resolution images are obtained from the withdrawal of water in dams to new constructions, from big fires to volcanic eruptions, from the damages caused by flood disasters to the unique natural landscapes of the earth.

Design Life Was 3 Years!

TÜBİTAK UZAY has produced RASAT without consultancy or external support, with the experience gained from BİLSAT, the first optical remote sensing satellite of our country, which was launched by technology transfer method in 2003.

With a design life of three years and successfully operating at an altitude of 700 kilometers, RASAT has successfully completed its 17th year in orbit as of August 2022, 11 and proved that Turkish engineers and technicians can produce a long-lasting satellite in space.

The First Local Satellite Imagery Portal: GEZGİN

In line with RASAT's mission planning, raw images taken to cover the whole of Turkey every year are downloaded to the ground station within TÜBİTAK UZAY. After geometric and radiometric corrections of the raw images are made, the leveled images are transferred to the GEZGİN Portal (www.gezgin.gov.tr). Citizens can access the images free of charge by logging into the portal with their e-government passwords to the GEZGİN Portal, which contains the latest images from 2020.

The owner of Satellite Technology Country: Turkey

TÜBİTAK UZAY; With the experience gained from RASAT and Göktürk-2 satellites and its infrastructure, equipment, human resources, it continues its effective, value-added activities and projects for innovative and high-local satellite-space technologies and applications.

It is advancing with determined steps towards the goal of developing critical space technologies in our country and becoming one of the few countries that can build their own satellites.
