The AngoSat 2 is a communications satellite built for Angola to replace the failed AngoSat 1. The Angosat Project calls for development of a communications satellite with C- and Ku-band transponders, its launch into a geostationary orbit and development of the ground communication and TV broadcasting infrastructure. In August 2019 it was revealed the replacement satellite is being built by ISS Reshetnev (Bus) and Airbus Defence & Space (payload). Construction has started in February 2018.
Geostationary OrbitRAISE-3 (RApid Innovative payload demonstration Satellite-3) was a satellite for on-orbit demonstrations of 7 demonstration components and equipment selected by public solicitation. The satellite was to be operated in response to requests from the demonstration theme proposers, and will provide experimental data of the demonstration devices and environmental data during the experiments. The launch is also carrying QPS-SAR 3 & 4 radar Earth observation satellites for iQPS, and 5 cubesats for various Japanese institutions & companies.
Sun-Synchronous 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 OrbitASO-S (Advanced Space-borne Solar Observatory) is a Chinese solar space observatory that aims to study the interaction between the Sun's magnetic field, solar flares and coronal mass ejections. It's the first space solar observatory of China. ASO-S is a 3-axis stabilized satellite with a mass of less than 1,000 kg with a pointing accuracy of 0.01° and an orientation stability of 1 to 2 arc seconds every 20 seconds. The payload has a mass below 335 kg and consumes about 300 watts. The platform's pointing accuracy is lower than 0.01°, the measurement accuracy is lower than 1 arc second and the orientation drift is below 0.0004°/s. ASO-S has three instruments: - The Full-Disc Vector Magnetograph (FMG) instrument is intended to map the magnetic field of the photosphere over the entire solar disk. It includes an imager, an optical polarization system and a CCD detector. - The Hard X-ray Imager (HXI) camera should image the whole solar disk in X-rays. The instrument is optimized to take images of solar flares. - A set of three LST (Lyman-alpha Solar Telescope) telescopes is used to observe the Lyman-alpha line (121.6 nm) of solar flares up to a distance of several solar radii from the Sun's disk. These three telescopes are SDI (to obtain an image of the solar disk), SCI (coronagraph for observation between 1.1 and 2.5 solar radii) and WST (white light emitted by the solar disk used for calibration purposes).
Sun-Synchronous OrbitThe “It Argos Up From Here” mission will launch the General Atomics Electromagnetic Systems designed and manufactured satellite GAzelle, carrying Argos-4 Advanced Data Collection System (A-DCS) hosted payload, part of the international Argos program that collects data from thousands of sensors and transmitters located around the world.
