Increased Performance

The novel HPGP monopropellant, called LMP-103S, provides increased performance compared to hydrazine. The specific impulse is ≥ 6% higher and the propellant density is 24% higher. As a result, the satellite can either be fitted with a smaller tank, or the mission duration can be extended while retaining the same tank size.

LMP-103S is based on ADN, has a very high energy content and can be stored for more than 20 years. It is also insensitive to space radiation. The thruster, including the catalyst and propellant, have been patented by ECAPS.

Simplified Handling During Fueling

Fueling with hydrazine requires a rigorous regime of safety procedures; including the use of SCAPE suits by fueling personnel. With LMP-103S, the procedures are much simpler, with only normal protective clothing for chemical handling required. This makes pre-launch fueling both faster and less
expensive. Unlike hydrazine, LMP-103S is also insensitive to air and humidity, making it much easier to handle and de-fuel, if necessary.

Simplified Propellant Transportation

LMP-103S is transport classified as both UN and US DOT 1.4S. This means that it can be transported to the launch site by air together with the satellite, rather than requiring a separate shipment by land or sea. Consequently, both transport costs and time can be saved. Transport by commercial passenger aircraft has been demonstrated numerous times to delivery destinations in Europe, the United States and Japan.

Reduced Environmental Impact

LMP-103S is environmentally benign compared with hydrazine, which is a highly toxic substance. So if your company has a clearly expressed environmental policy, HPGP will be an important component in its pro-environment profile.

And Ultimately: More Profitable Business

Lower costs or higher performance – irrespective of the specific needs of your specific satellite or launch vehicle project, HPGP adds value while also reducing environmental impact. We go so far as to claim that no other propulsion system technology can offer the same benefits.
