How Did It Go?

The China Aerospace Science Corporation (CASC) successfully launched the SuperView Neo 2-01 & 02 commercial remote sensing satellites into SSO. The satellites were carried by the Long March 2C rocket, from Taiyuan Satellite Launch Center (TSLC), in China. The SuperView Neo 2-01 & 02 mission marked the second launch for the SuperView Neo constellation.

SuperView Neo 2-01 & 02 Mission

The SuperView Neo 2-01 & 02 satellites were designed and manufactured by the China Association for Science and Technology (CAST) for China Siwei Survey and Mapping Technology Co. Ltd. (China Siwei), a leading company providing geospatial information services in China.

The company is developing a SuperView Neo satellite system, a successor of the existing SuperView-1 constellation. The SuperView Neo constellation will include at least 28 satellites of 3 series. The first one is called SuperView Neo-1 and it aims to provide 20 to 30 cm optical images. SuperView Neo-2 will produce synthetic-aperture radar (SAR) images with 50 cm resolution in spotlight mode, whereas SuperView Neo-3 will acquire large swath-width optical images with resolution higher than 1 meter.

On this mission, the first pair of SAR satellites (SuperView Neo-2) were launched.

The satellites will mainly provide remote sensing data services for domestic industries, including resource and environment monitoring and management, surveying and mapping, emergency management, and others. Moreover, they aim at the emerging market such as smart agriculture, urban information model, and intelligent transportation.

Long March 2C

The Long March 2C is a two stage medium-lift launch vehicle, with an optional third stage, derived from China’s Long March 2B vehicle. It is able to put up to 3,850 kg into low-Earth orbit, and up to 1,250 kg into geostationary transfer obit (GTO).

First Stage

The first stage has 4 open cycle YF-21C engines. Each engine runs on dinitrogen tetroxide (N2O4) and unsymmetrical dimethylhydrazine (UDMH), producing 740 kN of thrust each, with a specific impulse (ISP) of 260 seconds. Overall, the first stage produces 2,960 kN of thrust and carries 182,000 kg of propellant. The first stage is 25.72 meters tall, and 3.35 meters in diameter.

Second Stage

The second stage runs on a single YF-24E engine, which contains 1 main YF-22E engine for thrust, and 4 YF-23C attitude control thrusters. The main engine produces 816 kN of thrust and the attitude control thrusters each produce 47 kN, and both run on N2O4 and UDMH. The main engine’s ISP is ~300 seconds, and the attitude control thrusters have an ISP of 289 seconds. The second stage is 7.75 meters tall, 3.35 meters in diameter, and carries 162,700 kg of propellant.

Third stage

The third stage, the Yuanzheng, is a restartable upper stage. The variant used on the Long March 2C is designated YZ-1S. The Yuanzheng allows launch vehicles to deploy their payloads directly into high energy orbits, like medium-Earth orbit (MEO) and geosynchronous orbit (GSO). The stage features one YF-50D engine, which like the first and second stages runs UDMH and N2O4. It provides 6.5 kN of thrust and has an ISP of 315.5 seconds. The stage can perform at least two burns within its lifespan of 6.5 hours.
