Convergent Technology

Intelligence and advancement of state-of-the-art aerospace technologies

KARI is researching technologies to lead the future of aerospace in preparation for the Fourth Industrial Revolution and hyperconnected society that converges digital technologies such as AI and big data.

The institute researches the platform technology for converging visual data recorded by satellites and drones and artificial intelligence for analysis, drone cluster flight, microsatellite, space environment experiment, precise positioning for vehicle lane identification, and aerospace structural materials and 3D printing application technologies.

  • 01AI

    KARI is researching technologies that can analyze the image big data recorded by satellites and drones in real time. The advancement of image processing has enabled real-time big data analysis, significantly contributing to the improvement of operation efficiency. The technology can also provide big data to user agencies in Korea and abroad in a timely manner.
    Moreover, the institute is researching the autonomous drone flight that applies AI to the drone. The technology can allow drones to fly autonomously over areas that are difficult for satellites to record to acquire the data. KARI has developed the object detection technology in the radar satellite and the technology for enhancing the spatial resolution of the optical image to improve the resolution of satellite images; it is researching the application of deep learning technology to images of various wavelengths and resolutions.

  • 02Drone Group Flight

    KARI has developed the group flight of multiple drones by researching the precision location recognition of drone, communication with multiple drones, and precision control of drones. The RTK-GPS (Real-Time Kinematics-GPS) ultra-precise position recognition technology with error range of 10 cm enables multiple drones to fly without colliding with each other. KARI is also researching the convergence of AI and drone to apply the drone group flight to social safety such as finding missing people in disaster areas. The drone group flight technology is expected to create new added value when KARI transfers the technology to the industry.

  • 03Microsatellite

    A microsatellite is a satellite of low mass, usually under 500 kg, in the low orbit of 500 - 1500㎞. With 1U defined as a cube with 10-cm sides and weight of 1.3 kg, a microsatellite can be 3U, 6U, and up to 27U. Microsatellites can use conventional industrial-grade parts instead of much more expensive space-grade parts; thus, they can be manufactured economically and in a short time, too, and many of them can be deployed for a mission in various areas such as communication with earth-observing and low orbital satellites and space science experiments.

    KARI uses microsatellites to test future space exploration technologies and innovative technologies in space and conducts researches to apply them to medium-sized and large satellites. The institute localized the parts of microsatellites by developing the flight models of HiREV (High-Resolution Image and Video Nanosatellite), the 6U-(10kg, 10cm x 20cm x 30cm) class microsatellite, and accumulated experience in designing, manufacturing, and assembling microsatellites and testing them in the space environment. Moreover, KARI is developing four 6U microsatellites (SNIPE) for observing the near-earth space environment, and it will conduct the first space flight mission in Korea. KARI plans to use microsatellites actively to secure elemental technologies for the development of the technology for removing space wastes, technology for on-orbit servicing (OOS), and technology for space photovoltaic power generation. KARI has held the cube satellite contest each year, and it plans to launch the four microsatellites selected in the 2019 Cube Satellite Contest with the Korean launch vehicle Nuri.

  • 04Manned Space Experiment

    The manned space experiment is the basis for preparation for space exploration, and it can contribute to international cooperation such as international space station (ISS), gateway, and manned Mars exploration. KARI has operated internal cooperation programs such as the Korean model of the manned space program, application of micro-gravity environment, and development of core technologies for space experimental system in ISS. The institute is currently carrying out the development and performance testing of the earth model for life maintenance system, detection of fire inside the pressurized model, and fire safety control technology.

  • 05Precise Positioning for Vehicle Lane Identification

    The system provides reliable location data by reducing the location determination error to 0.9 m in the road transportation environment using the conventional GPS receiver. The GPS signal generates errors of 17 - 37 m in the user environment due to refraction and delay as it passes through the ionosphere and the atmospheric layer. The future self-driving vehicles and group navigation must overcome the error and identify the vehicle location within the lane (error of less than 1 m). Moreover, they must be able to recognize and provide guidance as to the reliability of the location data to assure user safety from false data due to the satellite navigation problem.

    KARI conducted the 24-hour test broadcasting service for the assessment of system safety in Southern Gyeonggi and Northwestern Chungcheong between August 2018 and January 2019 to verify the precise positioning for vehicle lane identification technology. The institute is currently developing the international standard to enhance technology competitiveness and expand the industrial ground. The precise positioning for vehicle lane identification technology will be applicable to self-driving vehicle level 4 or higher, which minimizes driver intervention. Its application is expected to be expanded to various areas such as smart devices, location-based service, and sporting event broadcasting/analysis.
