SATELLITE PROPULSION SYSTEM

TRL-9 QUALIFIED!

Providing station keeping, constellation management, decommissioning  and deorbiting to the small satellite market. Our MAPS™ solid propulsion system is highly configurable and compact, complete with high-performance capabilities. Demonstrated and proven on a 3u CubeSat, MAPS is compatible with many small satellites and spacecraft, such as a 6u CubeSat and larger. Qualifying as a cubesat propulsion system, our satellite thrusters are now flight proven!

MAPS is an array of high performance, hermetically-sealed, solid propellant rocket motors, all of which extend the orbital life of CubeSats and SmallSats while providing propulsion capability for small upper stages.  The attitude control thrusters are customized for CubeSat propulsion systems configurations at least 3u CubeSat or larger. Our system can be used for orbital maneuvers, attitude control, decommission and deorbit with very precise and predictable delivered impulse. There is not nozzle and the module has no tanks, valves, tubing or heaters, making it a “plug and play” bolt-on design.

SATELLITE THRUSTERS

MAPS is instant on with a 10+ year life, uses very low power (consumes little electrical energy), has three independent inhibits against firing, and provides variable thrust by firing in pairs, triples, quads, etc. MAPS, being easily adaptable and scale-able, fits in unused space or other spacecraft real-estate, including a lightband separation system.

Looking for a satellite propulsion system?

We want to learn more about your program needs and how we can help support your mission.

Our system, when compared to other liquid propulsion solutions, requires no hazmap scape or splash suits, no gloves, nor eye protection. It will take 1/5 the amount time (compare 149 days to completion vs. 33 days) from production to satellite launch vehicle integration. Finally, there will be no hazmat ground shipping and no propellant loading at the launch site. All of which mean it’s a great deal easier on you and your mission.

Concerned about those “dirty” pyrotechnic devices? There is no need, our thrusters will have no impact on any lenses or equipment.

SATELLITE CONTROL & CUBESAT DEORBIT

We can deliver very precise “impulse bits” to accurately control the position or attitude of a satellite. Reliability is of utmost importance in these systems since there is normally no real opportunity to service them over their entire lifetime. High performance is also a must; higher Isp systems provide additional on-orbit lifetime or the capability to increase the “payload” portion of the spacecraft, all of which our system can do.

Our satellite propulsion provides

  • Adjust for Injection Error
  • Drag Makeup
  • Rephasing
  • Change Orbit
  • Collision Avoidance
  • Attitude Control
  • Orbit Insertion
  • Station Keeping
  • Despin or Reorientation
  • Deorbit or Precision Re-entry

Interested in our Powered Modular Architecture Propulsion System (P-MAPS™)? P-MAPS provides a fully powered module to assist with decommission and/or deorbit of a satellite, enabling compliance with the 25-year lifetime restrictions in orbit.

Did you know, we made it into NASA’s iTech TOP 10 Semifinalists for Cycle 2 innovations? Learn more about NASA’s iTech program here.

PERFORMANCE CHARACTERISTICS

MISSION CHARACTERISTICS

  • No warm up time
    System is operational anytime in 300 Milliseconds
  • Always very precise, predictable, repeatable
    Distributed impulse bits (delta-V increments) reduces angular rate build up over fixed nozzle systems and improves delta-V predictability
  • High Isp performance
    Duty cycle independent: from pulse mode to steady state, delivered mission Isp is constant
  • Hermetically sealed motors
    Ready to fire immediately at satellite deployment or 10+ years later for deorbit/decommissioning
  • Safe, very clean burning propellant
    Will not contaminate optics or solar panels
  • System architecture
    Results in very high reliability
  • Very low power
    No heaters or valves
  • “Bolt-on/plug and play” system
    Leaves plenty of extra payload volume
  • Plug and play size and shape
    Customizable to fit the mission

Greatly reduces satellite factory cost
No integration of tanks, valves, fittings, or thrusters during satellite assembly


No fueling operations
Saves at least one week during launch vehicle integration with no propellant waste/disposal


Built-in-test (BIT) available
Anytime during mission operations from integration, launch, deployment and while on-orbit


Well known. Flight proven.
Solid propellant technology with three independent inhibit firing system, simplifies transportation and range safety approvals


Mission flexibility
Fire motors in pairs, triplets, quads, etc. for variable mission acceleration and delta-V flexibility

When it comes to choosing a satellite propulsion system and SW(M)AP
our system excels on all levels

  • Space: Fits into unused lightband volume
  • Weight (mass): Better than liquids – no valves, fittings, filters, large thrusters
  • Power: VERY low power: no heaters, solenoid valves, etc.
