=Gauss14= | |||
The Gauss14 is a femtosatellite launch platform. | |||
==Launcher== | |||
Based on the University of Austin Texas design for the SPEAR coilgun. Current goal is to launch projectiles with a mass of up to 10 grams. | |||
A SMES device (Superconducting Magnetic Energy Storage) is the most viable option for storing the launchers energy. | |||
==Satellite== | |||
The femtosatellite will most likely be based on the CubeSat or ArduSat, electronics must be hardend due to high g-forces during launch (up to several hundred g). | |||
====Propulsion==== | |||
A propulsion system without reaction mass is preferable. (tether propusion) | |||
A cooperation with other open source or non profit space programs is desireable. | |||
==Projectile== | |||
The first Prototype is a very cheap, reusable Projectile, launched not electromagnetically but by balloon or conventional chemical propulsion. | |||
===Guidance=== | |||
'''Requirements''' | |||
*Highspeed realtime positioning and Trajectory correction | |||
*Radiation, temperature and g-force hardened | |||
*Ultra low weight | |||
*Long range low power radio | |||
First choice for the autopilot would be the [http://1bitsquared.com/products/lisa-s Lisa/S] board for $300. | |||
Alternatively a custom prototype board could also be developed for about €5 to €50. | |||
===Control=== | |||
No suitable light weight solution found yet. | |||
===Capsule=== | |||
Heat and Radiation shielded light weight capsule with integrated miniaturized parachute system. | |||
==Major Challenges== | |||
====Efficiency==== | |||
Is currently the biggest challenge. Almost all Coilgun designs suffer from low efficiency of only 3 to 9 percent due to losses in the magnetic field and the projectile. | |||
====SMES funding==== | |||
The SMES is still in active research and apperently only a few prototypes are in existence. Aquiring (buying or borrowing one) might be difficult and expensive. | |||
