TDS-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 OrbitGOSAT-GW (Greenhouse Gases Observing Satellite Greenhouse gases and Water cycle), formerly known as GOSAT 3, is JAXA's next generation satellite to monitor the greenhosue gases like carbon dioxide in the Earth's atmosphere. It is the follow on to the GOSAT 2 (Ibuki 2) and GCOM-W (Shizuku) missions. GOSAT-GW will have two missions: greenhouse gases observation for Japan's Ministry of the Environment and the National Institute for Environmental Studies (NIES), and water-cycle observation for JAXA. By developing the GOSAT-GW satellite, Mitsubishi Electric will contribute to measures for preventing disasters attributed to global warming and climate change, and to advance scientific and technological methods that enable more accurate prediction of climate change. In December 2013, Mitsubishi Electric (MELCO) was selected as the prime contractor for the spacecraft and the instruments.
Sun-Synchronous OrbitHawkEye 360 is a a space-based civil global intelligence satellite network using radio frequency (RF) technology to help monitor transportation across air, land and sea and assist with emergencies, and to provide civil SIGINT (Signal Intelligence) mission. The constellation of small satellites (named Hawk ) will collect information on specific radio signals worldwide to provide high-precision radio frequency mapping and analytics from Low Earth orbit (LEO).
Low Earth OrbitIonosfera is a constellation of four ionospheric and magnetospheric research satellites developed by for Roscosmos for the project Ionozond. The satellites will operate on circular sun-synchronous orbits (SSO), at altitude of about 800 km and located in two orbital planes of two satellites each. The following science instruments are carried on the satellites: * SPER/1 Plasma and energy radiation spectrometer * SG/1 Gamma-ray spectrometer * GALS/1 Galactic cosmic ray spectrometer / 1 * LAERTES On-board Ionosonde * NBK/2 Low-frequency wave complex * ESEP Ionospheric plasma energy spectrometer * Ozonometer-TM Ozonometer * MayaK On-board radio transmitters * PES GPS-GLONASS device
