Translation help needed. My technical Chinese for space related areas is non-existent. Many thanks in advance.

These slides outline some major upcoming space projects in the next decade. They include Mars lander and other probes, broadband communication network made up of hundreds of micro-satellites, etc.

Something the twitter link did not mention
The first technical experiment satellite was launched in December 2018. Planned deployment to be completed in 2023.

The system is based on synthetic aperture telescope.

The satellite platform (DFH-5) is equipped with laser communication devices for inter satellite's communication of payload.

Worth noting is that the first test DFH-5 is to be launched soon on board CZ-5, either this December or early 2020.

With the launch Monday of a new pair of navigation satellites, China is one step nearer to achieving global coverage with its navigation satellite system. The launch of Beidou-3M19 (Beidou-52) and Beidou-3M20 (Beidou-53) took place at 07:22 UTC, lofted by the Long March-3BGZ/YZ-1 (Y67/Y15) from the LC3 Launch Complex at the Xichang Satellite Launch Center, Sichuan province. Deployment took place four hours after lift-off.

The MEO satellites are the Medium Earth Orbit component of the third phase of the Chinese Beidou (Compass) satellite navigation system. The satellites are part of a fleet expanding the system into global navigation coverage.

The satellites are using a bus that features a phased array antenna for navigation signals and a laser retroreflector, with a launch mass of 1,014 kg. Spacecraft dimensions are noted to be 2.25 by 1.0 by 1.22 meters. Usually, the satellites reside in a 21,500 – 21,400 km nominal orbit at 55.5 degrees.

The satellites are equipped with lightweight hydrogen maser clocks, which will serve as a more stable precision frequency reference to make the satellite navigation system work more accurately.

This was the seventh launch dedicated to the replenishment of the Beidou Navigation Satellite System in 2019, with launch activities starting on April 20th with the launch of Beidou-3IGSO-1 (Beidou-44) satellite from the LC3 Launch Complex of the Xichang Satellite Launch Center using the Long March-3B/G2 (Y59).

The article forgot to mention the most significant thing about this launch (52 and 53). It completed the MEO constellation of 24. 24 MEO alone is functionally equivalent to the whole GPS or Glonass system, therefor regarded as the "core". The GEO and IGSOs are to further improve accuracy and SBAS, and they are all in place already. The two last launches in 2020 will be to replace the Beidou 2 version of GEO/IGSO already on orbit, can be seen as upgrade.

In summary, all satellites are in orbit pending commission.

The satellite is the sixth satellite under the earth resource satellite cooperation program between the two countries. It will obtain global optical remote-sensing data and support the Brazilian government's monitoring of the Amazon rainforest and the country's environmental changes.
