+=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
-=Gauss14=
+First choice for the autopilot would be the [http://1bitsquared.com/products/lisa-s Lisa/S] board for $300.
-The Gauss14 is a manportable femtosattelite launch platform. Based on the University of Austin, Texas design for the SPEAR coilgun.
+Alternatively a custom prototype board could also be developed for about €5 to €50.
+===Control===
+No suitable light weight solution found yet.
-==Femtosatellite==
+===Capsule===
-The femtosatellite will most likely be based on the CubeSat or ArduSat.
+Heat and Radiation shielded light weight capsule with integrated miniaturized parachute system.
-==Projectile First Prototype==
+==Major Challenges==
-The first Prototype will be a very cheap, reusable Projectile, launched not electromagnetically but by balloon or conventional chemical propulsion.
+====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.
