Bradford ECAPS's 1N HPGP Thruster is designed for attitude and orbit control of small-sized satellites. With 46 1N HPGP thrusters having been demonstrated to date aboard the PRISMA spacecraft and the SkySat series, the 1N HPGP is Bradford ECAPS' most heritage line of thrusters and most popular with small to medium sized spacecraft, up to 750 kg. The high performance and non-toxicity is highly prized by developers of agile and responsive spacecraft and particularly suited for the fast-paced NewSpace industry.
The 1N HPGP 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.
- Higher performance over hydrazine allows for more payload or longer mission durations.
- 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.
