The Quasi-Zenith Satellite System (QZSS) is a three-satellite regional time transfer system and the satellite-based augmentation system for the GPS that would be receivable within Japan. The primary purpose of QZSS is to increase the availability of GPS in Japan's numerous urban canyons, where only satellites at very high elevation can be seen. A secondary function is performance enhancement, increasing the accuracy and reliability of GPS derived navigation solutions. A single satellite weighs about 4000 kg, has an expected lifetime of 15 years and is put in a elliptical, highly inclined geosynchronous orbit.
Geosynchronous Transfer OrbitInmarsat-5 F4 is the next addition to the fifth generation of Inmarsat satellites. Inmarsat-5 satellites each carry 89 Ka-band beams and deliver high-speed mobile broadband communications for deep sea vessels, in-flight connectivity for airline passengers, streaming high-resolution video, voice and date to the enterprise sector, and secure solutions for government customers. The satellite weighs 6100 kg at launch and has an operational lifetime of 15 years.
Geostationary Transfer Orbit B1034 - Maiden Flight Atlantic OceanGSAT-9 is a multi band communication and observation satellite. It carries a GAGAN (regional Indian GPS navigational system) navigation payload to provide GPS services to security forces and air traffic control organizations. Weighing about 2330 kg, satellite has an operational lifetime of 12 years.
Geostationary Transfer OrbitBoth SGDC 1 and Koreasat 7 are geostationary telecommunications satellites. SGDC 1 is a 5800 kg satellite for Brazil, equipped with 50 Ka-band and 7 X-band transponders, and intended for both civil and military use. Koreasat 7 is to provide internet access, multimedia, broadcasting and fixed communications services to South Korea, Philippines, Indonesia and India. Satellite weighs around 3500 kg, and its operational lifetime is 15 years.
