CHORUS is MDA's next generation Earth observation constellation, consisting of 2 radar satellites (C-band SAR and X-band SAR), in a 53.5 degree 600 km altitude LEO, with the X-band trailing the C-band by 60 minutes. A collaborative multi-sensor constellation, CHORUS will bring together diverse and unique imagery and data sources and provide a new level of near real-time insight and innovative Earth observation services. Operating in a unique mid-inclination orbit, CHORUS will be able to image day or night, regardless of weather conditions, with daily access of up to 95% of the coverage area. From an industry-leading 700km-wide imaging swath down to sub-metre high resolution, CHORUS will provide the most extensive and unrivalled Earth observation radar imaging capacity available on the market in a single mission.
Low Earth OrbitGlonass-K are the third generation of satellite design for GLONASS satellite navigation system. GLONASS is a Russian space-based navigation system comparable to the similar GPS and Galileo systems. This generation improves on accuracy, power consumption and design life. Each satellite is unpressurized and weighs 935 kg, and has an operational lifetime of 10 years.
Medium Earth OrbitThe Electro-Optical/Infrared Weather System (EWS) Operational Demonstration-1 (OD-1) is a weather satellite for the United States Space Force. It is a prototype satellite made by General Atomics that will be place in LEO for a three-year demonstration mission of new EO/IR sensor technologies to various US military branches, and to act as a stop-gap for Defense Department needs for weather data.
Sun-Synchronous OrbitThe Engineering Test Satellite 9 (ETS-9) is a JAXA project aimed to develop an advanced satellite bus, or common model, for various high-throughput satellites (HTS) for communications. The new satellite bus by Mitsubishi Electric will focus specifically on advanced communication needs: - Up to 25kW of power to support HTS communications - Light mass, all-electric bus system achieved with 6kW high-power Hall thrusters (Japan-made). - High-power Hall thrusters significantly shorten delivery of orbiting satellite compared to other manufacturer’s 4.5kW-class electric-propulsion bus systems - The first Japanese geostationary satellite equipped with GPS receivers (Japan-made) for laborsaving autonomous orbital transfer and orbital maneuvering.
Geostationary Transfer OrbitThe Lunar Polar Exploration mission (LUPEX) is a robotic lunar mission jointly developed by the Indian Space Research Organisation (ISRO) and Japan Aerospace Exploration Agency (JAXA), deploying a lunar rover and lander to explore the south pole region of the Moon. JAXA will provide the under-development H3 launch vehicle and the rover, while ISRO would be responsible for the lander.
Lunar OrbitQZSS (Quasi Zenith Satellite System) is a Japanese satellite navigation system operating from inclined, elliptical geosynchronous orbits to achieve optimal high-elevation visibility in urban canyons and mountainous areas. The navigation system objective is to broadcast GPS-interoperable and augmentation signals as well as original Japanese (QZSS) signals from a three-spacecraft constellation. The navigation system objective is to broadcast GPS-interoperable and augmentation signals as well as original Japanese (QZSS) signals from a three-spacecraft constellation in inclined, elliptical geosynchronous orbits.
