Feb 24, 2012 · Vietnamese students have produced a video about their amateur radio CubeSat F-1, callsign XV1VN. The F-1 is an educational CubeSat to be launched in the summer of 2012. It will carry a low resolution C328 camera with 640x480 resolution and two Yaesu VX-3R transceivers using 145.980 and 437.485 MHz.

Abstract A problem of circular cylindrical dipole antenna is revisited. Reflectarrays work sort of like a Fresnel lens, which squashes a thick lens down into an array of little prisms. The little rectangular patches (or circles, or ellipses, depending on the design..

Dec 21, 2015 · If you go for a linear antenna the loss is 3db from satellites with circular polarisation but 20db when you hit the wrong linear polarisation. Therefore its safe to assume that cubesats usually just have a (linear) stub antenna and you have a max loss receiving with circular polarisation of 3db worst case. For VHF and UHF, you can mount the antenna in a housing and then clamp it to a mast rather than using rope or something similar to elevate it. I used some 20 mm conduit, a matching T-piece (the type with the inspection plate so you can join the element to the feeder) and end caps to make a housing for the dipole.

1.1The CubeSat Standard The CubeSat concept, developed at the Stanford University, was designed in order to make it easier to launch student satellite projects at a lower cost comparing to commercial satellites. The original CubeSat was a cube of size 10cm 10cm 10cm, named 1-U and weighing at most 1 kg. A deployer was also developed, namely P-POD

In this letter, a new conductive composite tape-spring is proposed for CubeSat deployable antennas that is constructed using a glass fiber reinforced epoxy with an embedded copper alloy conductor. The tape-spring is bistable enabling the antenna to be elastically stable in both the deployed and stowed states. A dipole antenna is designed, simulated, and tested to prove the viability of the ...

The ISIS CubeSat antenna systems can support a wide range of frequencies in both VHF and UHF bands using up to four tape antennas. These systems provide your CubeSat an optimal transmission quality and system reliability at a minimal volume. The outer face of the antenna system can accommodate a solar panel or it can be customized for accommodating sensors or other systems which protrude outwards, e.g. camera apertures. To that end it will carry a full size 10m wire dipole antenna. The 30KHz wide transponder is an inverting design intended to cancel out the effects of Doppler shift. ... Since the first CubeSats ...

Jan 01, 2010 · An active attitude, which consumes the energy, is avoided by using omnidirectional antenna. In the case of early launch CubeSats, the CubeSats that have adopted permanent magnets as passive attitude control, still alive and operated well. On the contrary, other Cubesats that incorporated active attitude control had many problems and was unstable.
