Bradford ECAPS's 1N GP Thruster is designed for attitude and orbit control of small-sized satellites. This in-development model is a variant of the 1N HPGP Thruster, for cost-critical missions where affordability takes priority over performance.
The 1N GP thrusters can be provided individually or as an integrated system. For instance, each SkySat propulsion system consisted of four 1N HPGP thrusters along with tanks, flow regulators and other avionics.
- Non-toxic propellent makes for easier and less costly integration on secondary or 'piggy-back' missions.
- Propellant loading is simple, fast and avoids the cost associated with loading hydrazine. Allows the operator to spend less time on ground operations and more time on space operations.
- 'Fuel at the factory' – be ready for launch vehicle integration upon arrival at the launch pad.
- Allows for more secondary or 'piggy-back' launch opportunities, especially missions where there is concern about the hazards of hydrazine and its risks to the primary payload.
- Allows for more capable missions than spacecraft without propulsion.
- Allows for more agile mission profiles than electric propulsion. Spacecraft take significantly less time to execute maneuvers and orbit changes.
- Although not as high as the 1N HPGP, the 1N GP still provides equivalent to greater performance and storage density over hydrazine.
- Less costly thruster system (equivalent to hydrazine) allows for lower cost system build.
