Introduction to CubeSat

CubeSat-training-tonex-intro

Once considered an educational curiosity, CubeSats have steadily garnered more responsibility in the general realm of space exploration and use cases.

CubeSats are miniature satellites that have been used exclusively in low Earth orbit for 15 years, and are now being used for interplanetary missions as well.

NASA has been particularly active in CubeSats design and research objectives. NASA runs the extensive Small Spacecraft Technology Program as well as the CubeSat Launch Initiative. Previously selected CubeSats have studied near-Earth objects, space weather, Earth’s atmosphere and much more.

Scientists and organizations have discovered several benefits from deploying CubeSats, such as:

  • Fast: can be built within two years.
  • Cost: far less expensive than large satellites.
  • Technology: simple, standard parts available off-the-shelf.
  • Design: simple design for short mission; no need to use thermal blankets.
  • Space debris: none – they burn up in the atmosphere upon reentry.

CubeSats are put into orbit by deployers on the International Space Station, or launched as secondary payloads on a launch vehicle.

The electrical power system (EPS) consists of solar panels and batteries. Solar panels hold solar cells that convert the solar light from the sun to electricity. Batteries take up a lot of mass and volume on the already tightly packed CubeSat. A major design challenge is placing the solar panels, either on the sides of the CubeSat itself, or having deploying solar panels.

In L-band, CubeSats can take advantage of legacy communications networks such as Globalstar and Iridium by using network-specific transponders to relay information to and from Earth. These networks remove dependence on dedicated ground station equipment.

Because of their quick development time and easy access to space, CubeSats have become the perfect platform for demonstrating how a new technological advancement will perform in orbit.

Introduction to CubeSat Course by Tonex

Introductions to CubeSat is a 2-day covering the basic concepts and processes for
CubeSat analysis, design and developments. Participants will learn about the CubeSats or miniature satellites that have been used exclusively in Low Earth Orbit (LEO), and can be used for exploring and interplanetary missions. In the beginning,    however, they were commonly used in low Earth orbit for applications such as remote sensing or communications.

Nanosatellites are loosely defined as any satellite weighing less than 10 kilograms. The basic design of a CubeSat is a 10-centimeter (4-inch) cube with a mass of less than 1.33 kilograms (2.93 lbs.). CubeSats can also be designed to encompass two, three or six 10-centimeter units for more complicated missions. CubeSats shall also comply with a series of specific criteria that control factors such as their shape, size and weight.

What is a Nanosatellite?

The standard CubeSat unit, a cube-shaped structure measuring 10x10x10 centimetres, has with a mass of somewhere between 1 and 1.33 kg (AKA as 1U). This modular unit is now multiplied and larger nanosatellites such (1.5U, 2U, 3U or 6U).
