Vietnam: Procedures for capturing images at Satellite Receiving Station

Vietnam: Procedures for capturing images at Satellite Receiving Stations (Internet image) 

According to Circular 39/2015/TT-BTNMT, the process for receiving images at the satellite ground station in Vietnam is conducted as follows:

- Prior to image reception, the following preparations are to be made:

- Check the readiness status of the equipment: antenna; antenna control equipment; frequency conversion equipment; signal detection equipment; frequency spectrum analyzer; signal demodulator, GPS equipment, wind measurement device.

- Test run the antenna control system; check the technical parameters of the equipment after the test run and record the parameters in the logbook.

- Check the equipment in the room, the operational status, and configurations of the reception, processing, and storage servers.

- Review the image reception plan and the time synchronization between the antenna control system and the signal processing system.

- In case of a conflict in the image reception schedule between satellites, seek the opinion of the ground station manager to choose the satellite with higher priority.

- Once the preparations for image reception are completed, proceed with the following steps:

- Receive and process satellite signals;

- Evaluate the quality of remote sensing images;

- Assess cloud cover extent;

- Update the remote sensing image data catalog;

- Backup remote sensing data at level 0;

- Monitor and evaluate remote sensing image acquisition orders;

- Report the results of remote sensing image acquisition;

- Process remote sensing data from level 0 to basic levels.

Note that the processing of remote sensing data from level 0 to producible remote sensing images at the ground station is only performed upon the request of authorized personnel.

More details can be found in Circular 39/2015/TT-BTNMT, which comes into effect in Vietnam from July 9, 2015.
