The Independent Space Exploration Commission, known as ISEC, is an independent, privately funded spaceflight and exploration organization. The organization was created by Luke Pilcher. ISEC advertises itself as the "only" open-source spaceflight company/organization in existence. ISEC's current fleet of rockets include a line of composite airframe solid fueled rockets for short-range to suborbital launches known as the CAELUS or Research Launch Vehicle(RLV) launch family as well as its multi-stage/multi-configuration Payload Transport System which has a solid fueled core stage and a liquid fueled 2nd stage and optional solid fueled boosters in a 2 or 4 booster setup.

Propulsion
The propellant mixture in the rockets and boosters consist of Ammonium perchlorate (oxidizer, 69.6% by weight), Aluminum (fuel, 16%), Iron oxide (a Catalyst, 0.4%), Nitrocellulose (a binder that holds the mixture together and acting as secondary fuel, 14%). This propellant is commonly referred to as Ammonium Perchlorate Composite Propellant, or simply APCP. This mixture is very similar to that used on NASA's Space Shuttle Solid Rocket Boosters except no curing agent is used and a slightly higher binder content. The propellant has a 5-point finocyl bore all the way from the forward bulkhead to aft end. Thrust vectoring is provided through 4 linear actuators controlling pitch and roll on its 2 axis nozzle support. No thrust vectoring is used on RLV-1H boosters.

Electronics/Guidance
All electronics on-board are either located or centrally controlled in the forward electronics bay which contains the Flight Dynamics Computer(FDC).

Sub-systems include:
 * Thrust Vectoring micro-controller
 * Solid State Data Recorder
 * GPS System
 * Imaging Controller(Independent of FDC)
 * 2.4Ghz & 433Mhz communication links
 * Range Safety System
 * Recovery System
 * Booster Separation Control(RLV-1H)
 * Sat-Com communication system(RLV-1H)
