It was the first product to be built in Vietnam in the space technology field. The target for this project is to co-operate in space technology development between Vietnam and Japan. It is also the first Vietnamese satellite to launch successfully to space. Before the launch of PicoDragon, there had been 4 satellites launched into orbit: VNREDSat 1A, F-1, Vinasat-1 and Vinasat-2 although F-1 failed upon its launch. Vinasat-1, Vinasat-2, VNREDSat 1A were all built by foreign partners or companies.^{[citation needed]}

At 2:48 AM (UTC+07:00), 4 August 2013, PicoDragon was successfully launched to the ISS via the transport spacecraft HTV-4, followed by ArduSat-1, ArduSat-X, TechEdSat-3 of United States and Kirobo robot of Japan, all of which were launched at Tanegashima by Kounotori of Japan.^[3] Before its placement into orbit from the ISS, it was held back for additional checks.^{[citation needed]}

PicoDragon was a 1U CubeSat project designed for low resolution Earth imagery and to test on-board systems.^[4]

On 19 November 2013 (Vietnamese time), PicoDragon was launched into orbit by the ISS.^[5] 4 hours after the launch, the first signals of PicoDragon were successfully received by the ground station in Japan. After that, VNSC's ground station also received signals from PicoDragon. After more than 3 months in orbit, PicoDragon - Vietnam's first microsatellite completed the mission and burned upon atmospheric entry back to Earth.^[6]

PicoDragon's mission has been deemed sufficient, and in its 3-month orbit, it transmitted an advertising signal "PicoDragon Vietnam" (PicoDragon Việt Nam) to ground-based radio stations.

According to professor Pham Anh Tuan, director of VNSC, after PicoDragon, Vietnam will build more satellites with larger sizes (10 kilograms (22 lb) in 2015 and 50 kilograms (110 lb) in 2017) and will launch a 500 kilograms (1,100 lb) satellite to observe the Earth from space in 2020.^{[citation needed]}
