Glonass-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 OrbitProba-3 (Project for On-Board Autonomy 3) is the first close formation flying mission for the European Space Agency (ESA). It consists of two independent, three-axis stabilised spacecraft flying 150 meters from one another with the ability to accurately control the attitude and separation of the two craft. Such formation flying will be maintained for 6 hours, creating ″artificial solar eclipse″ for the satellite below. The spacecraft pair will fly a highly elliptical orbit divided between periods of accurate formation flying around apogee, when payload operations will be possible, and periods of free flight.
Elliptical OrbitTDS-01 (Technology Demonstration Satellite-01) is an Indian geostationary orbit technology demonstration satellite carrying payloads for the Indian Space Research Organisation (ISRO)’s Institute of Plasma Research, Gandhinagar and the CSIR-CEERI, Pilani. Payloads to be tested included an internally developed 300 mN electric powered thrusters, atomic clocks, travelling wave tube amplifiers (TWTA) & a quantum communication suite (QuTDS).
Geostationary Transfer OrbitASTRA 1P, a classic wide-beam satellite, will support SES’s prime TV neighbourhood and enable content owners, private and public broadcasters across Germany, France and Spain to continue broadcasting satellite TV channels in the highest-picture quality in the most cost-efficient manner. It will be based on the full electric and powerful Spacebus NEO platform developed by Thales Alenia Space and already flight proven in orbit.
Geostationary Transfer OrbitTwo satellites for Europe's Galileo navigation system. Originally planned for launch on Soyuz-ST and then Ariane 6 but both were unavailable. Galileo provides Europe with an alternative to the American GPS and Russian GLONASS constellations, but will be interoperable with both systems.
