Satellite

In Korea, only Hanwha Systems can provide both EO·IR and SAR payloads.
We provides electro-optical modules and SAR modules for military satellites that monitor the Korean Peninsula and neighboring countries on near-real time basis, maximizing the effects of joint operations of Army, Navy and Air Force. It also provides network controllers and various terminals for military satellite networks. Based on its unrivalled capabilities in satellite area, particularly for electro-optics, SAR radar, communications and small satellite systems along with its large pool of in-house satellite experts, We are undertaking the tasks of developing military satellite SAR and EO·IR payloads and is also leading the small satellite development to be aligned with New Space Paradigm.
Going forward, we will further upgrade satellite mission designs and system development technologies by targeting small satellite constellation operations in accordance with New Space Paradigm, which will help us to secure the leading position in satellite business.

KOMPSAT(Multi-Purpose Satellite) 3A IR Sensor

KOMPSAT 3A is a satellite equipped with both sub-meter level optics camera and infra-red sensor providing day/night imaging. For KOMPSAT 3A, Hanwha Systems successfully developed the world’s top-notch level infra-red sensor payload, which also marked Korea’s first success in that category.
At present, KOMPSAT 3A is still in operation with its mission lifetime extended by 4 more years. We are currently developing its follow-on models, KOMPSAT 7 and KOMPSAT 7A, that are the world’s most advanced type of satellites with super resolution imaging payloads.
As a company specialized in electro-optics payload system for KOMPSAT, after completing its development tasks for KOMPSAT 3A successfully, we are now working on the development of its follow-on models, KOMPSAT 7 and 7A. We expect that we will secure the highly sophisticated satellite technologies on a par with those of the world’s most advanced satellite developers.

Compact Advanced Satellite I & II Electro-Optics Payload

Hanwha Systems became the first Koran company to participate in the electro-optics payload development for Compact Advanced Satellite(weighing about 500 kg) Project. The Project was intended to develop Korea’s indigenous satellite technology and more effectively respond to the public needs for national territory and resource management, weather and environment observation and disaster management by using satellites. Following the Korean government’s space industry promotion policy, we collaborated with KARI(Korea Aerospace Research Institute) to develop 0.5m level electro-optics payload and secured payload system integration technology thru technology transfer. Thanks to the success of this R&D effort, we laid the foundation to lead electro-optics payload development for Compact Advanced Satellite Program.

Small SAR Satellite System and
Payload Development

SAR payload with electronic beam steering capability of the global top tier level.
In order to effectively respond to the future security environment and build the foundation for Korea’s indigenous development of small SAR constellation satellite systems, Small SAR Satellite EQM(Engineering & Qualification Model) Project is underway as one of the Future Technology Challenge Initiative Program, in which Hanwha Systems is actively participating.
Small constellation satellite brings such advantages as low cost, short development period, quick orbit reaching, etc. compared with the existing mid-to-large sized satellites. In particular, small constellation satellite has very short revisit time cycles, which allow for expedient mission performance and express data acquisition.
Unlike the designs for existing satellites, innovative designs per New Space Paradigm are applied to SAR constellation satellite, which include integrated SAR antenna-main unit structure as well as functional integration. This makes the system lighter and simplifies satellite’s electrical interfaces. Thru these design innovations, SAR satellites have secured economic feasibility while accelerating development schedules.
In particular, our SAR payload, currently being developed based on Korea’s indigenous technology, applies active array elements for electronic beam steering, which makes it possible to acquire high resolution (1m-level) images for a wider scope. We will develop this technology to be also applicable to BUS(Basic Unit System) and payload-separated type satellites in the future.
