The F-1 CubeSat, callsign XV1VN, developed by the FSpace team of young engineers and students at the FPT University, deployed from the International Space Station (ISS) on Thursday, October 4 at 15:44 UT. A Google English newspaper report with pictures of the F-1 team’s attempts to receive the satellite after deployment can be seen at http://tinyurl.com/Chungta-F-1-Article. F-1 Keps (1998-067CP) are at http://celestrak.com/NORAD/elements/tle-new.txt.
On Sunday, October 7 Thu Trong Vu XV9AA provided this update:
So far the team has received several mixed reports about F-1 status, there is no definite conclusion yet. We will continue to collect information and analyze the situation, this afternoon we will hold a team meeting to discuss different situations that may happen with the little satellite up there. Please continue to help us listening for F-1 on 437.485 in daylight and 145.980 in the dark, thank you!

F-1 CubeSat on its way to International Space Station

The amateur radio F-1 CubeSat, built by the FSpace team of young engineers and students at the FPT University, is on its journey to the International Space Station (ISS). It is the first satellite to be built in Vietnam and the project has attracted much TV news coverage.
F-1 carries a low-resolution C328 camera for an earth observation mission. The camera is capable of a maximum resolution of 640 by 480 pixels with 8 bit color. Images will be downloaded when commanded by the FSpace ground station.
There is a 3-axis magnetometer (developed by Angstrom Space Technology Center, Uppsala University, Sweden) and several temperature sensors.
The satellite’s callsign is XV1VN and the communications subsystem is built around two Yaesu VX-3R amateur radio handheld transceivers. One will operate on UHF the other on VHF.
Yaesu VX-3R1 transmits on 437.485 MHz FM, it has no battery so will operate on solar power only. As a result it will only be active when the satellite is in sunlight and when active the output power will vary between 0.1 and 0.3 watts depending on the amount of illumination. The antenna is a half-wave dipole. The FM beacon will send Morse code at 10 words per minute every 30 seconds (configurable). A sample of the beacon can be heard here.
VX-3R2 operates on 145.980 MHz FM and is connected to Lithium-Polymer (LiPo) batteries so will operate in both dark and sunlight. The power output is 1 watt into a half-wave dipole antenna. Using a TinyTrak4 packet radio modem it will send an AFSK 1200 bps AX.25 packet every 60 seconds (configurable).
F-1 was launched along with four other CubeSats in the HTV-3 cargo vessel on an H-IIB rocket from the Tanegashima Space Center, Japan, on July 21 at 02:06 UT and will arrive at the ISS on July 27.
It will remain on the ISS until September when it will be deployed by Japanese astronaut and radio amateur Akihiko Hoshide KE5DNI using the ISS Kibo robot arm.
F-1 is mounted in a JEM-Small Satellite Orbital Deployer (J-SSOD) with the amateur radio TechEdSat and FITSat-1 CubeSats. In a second deployment pod are WeWish and a scientific 2U CubeSat Raiko. The CubeSats will be deployed into a 400 km orbit and should have a lifetime of 3 or 4 months before re-entering the Earth’s atmosphere and burning up.
In this video the team from FPT University sing the song “Vietnam’s orbit”. Artist/singer Trương Quý Hải has supported the F-1 CubeSat project from the beginning and composed the song just a few weeks before the launch. The accompanying music clip was completed just hours before the launch of F1. The team very much appreciated this.

Live TV broadcast for launch of HTV-3 CubeSats
FSpace, the team of young engineers and students at the FPT University who developed the amateur radio F-1 CubeSat, report on the final launch preparations for the HTV-3 cargo vessel that will carry five CubeSats to the International Space Station (ISS).
FSpace say final inspection was performed on July 9, and from July 13-15, a rehearsal was conducted simulating the launch operation. Late access cargo loading will continue until July 19 then the hatch will be closed and the H-IIB launch vehicle with the HTV-3 will be moved to the launch pad. The launch is planned for July 21 at 02:18 UT.

F-1 CubeSat Delivered to Tsukuba Space Center
The amateur radio CubeSat F-1 built by students at the FPT University in Hanoi, Vietnam has now been delivered to the Tsukuba Space Center in Japan.
F-1 and the other four CubeSats (RAIKO, WE WISH, FITSAT-1 and TechEdSat) will be integrated with the small satellite deployer J-SSOD before leaving for Tanegashima launch pad.
The CubeSats should be launched to the International Space Station (ISS) on July 21 in the HTV-3 cargo vessel. It is planned that they will be deployed from the ISS in September by Japanese astronaut Akihiko Hoshide KE5DNI using the Kibo robot arm.
F-1 carries a low-resolution camera (640×480), a 3-axis magnetometer and two Yaesu VX-3R transceivers using 145.980 and 437.485 MHz.
