Vietnam Launches Satellite with AIS

Vietnam launched a 4 Kg Cubesat – named Nano Dragon, developed by scientists from Vietnam National Space Centre (VNSC).  The satellites were successfully placed into orbit at an altitude of about 560km. Uchinoura Space Centre Japan Aerospace Agency (JAXA) launched the payload by the Epsilon 5 rocket.

JAXA(Japan Aerospace Exploration Agency) had to reschedule the launch of the Epsilon 5 rocket three times due to bad weather and technical problems. Finally, Nano Dragon along with eight other satellites successfully launched on 9th November 2021 at  09:07 AM from the Japanese town of Kimotsuki, Kagoshima Prefecture.

The satellite is tasked with two important missions.

Operating in orbit at an altitude of about 560km it will receive signals to identify vessels, through AIS (Automatic Identification System) and send the signals to the monitoring centre to check the entry and exit of vessels as well as help avoid collisions.

The second mission of Nano Dragon is taking aerial photos to help scientists perfect satellite navigation systems.

Vietnam National Space Center (VNSC), Vietnam Academy of Science and Technology have published downlink communication parameters of our NanoDragon satellite as follows:

  • Frequency: 437.365 MHz (UHF band)
  • Baudrate: 1.2 kbps
  • Receiver’s filter: Square-root raised cosine (SRRC)
    • Roll-off factor 0.5
  • Modulation: BPSK

Amateurs are requested to monitor the frequency and submit their report to [email protected]

All information about the satellite will be very much appreciated by the team.
