QZSS (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.
Geosynchronous Transfer OrbitAST SpaceMobile’s Block 2 BlueBird satellites are designed to deliver up to 10 times the bandwidth capacity of the BlueBird Block 1 satellites, required to achieve 24/7 continuous cellular broadband service coverage in the United States, with beams designed to support a capacity of up to 40 MHz, enabling peak data transmission speeds up to 120 Mbps, supporting voice, full data and video applications. The Block 2 BlueBirds, featuring as large as 2400 square foot communications arrays, will be the largest satellites ever commercially deployed in Low Earth orbit once launched. This launch will feature a single satellite.
Low Earth OrbitThe Russian Obzor-R satellite is a planned X-band radar earth observation satellite designed by TsSKB-Progress. In 2012, the development of the Arkon-2M radar satellite was stopped and instead the development of the Obzor-R was initiated. The satellite features the BRLK X-band Synthetic Aperture Radar as the imaging instrument with a ground resolution of 500 m.
Sun-Synchronous OrbitA pair of Russian optical Earth observation satellites built by the Progress Rocket Space Centre for obtaining stereo images of the Earth's surface, with maximum resolution of 1.2 m in panchromatic mode and a swath width of 32 km. 20 small satellites will also be launched as ride-share payloads.
