The Globalstar global mobile communications network offers global, digital real time voice, data and fax services via its Low Earth Orbit satellite constellation. The constellation operates in a 1410 km orbit inclined at 52 degrees. In early 2022, Globalstar contracted with MDA for the construction of 17 new 3rd generation satellites to replenish the existing constellation. Rocket Lab is sub-contracted to build the satellites' buses and the launch dispensers.
Low Earth OrbitCHORUS 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.
