Applicable to satellite platforms weighing 200~400kg, used for satellite orbit raising, long-term attitude control, and deorbiting. The use of efficient gas distribution and magnetic focusing technologies results in higher ionization rates, with significant improvements in both thrust and specific impulse. The cathode options include lanthanum hexaboride or barium tungsten, and krypton can be used as a more cost-effective propellant, making it particularly suitable for low Earth orbit broadband networks, communication and remote sensing satellites with high specific impulse and low-cost requirements. The product has high technological maturity, with flight experience in orbit, and excellent performance indicators.
Technical Features:
1. Multi-mode operation, allowing real-time adjustment to meet different thrust levels.
2. Lanthanum hexaboride cathodes offer stronger oxidation resistance and longer lifespan, while barium tungsten cathodes have low power consumption, suitable for low-power output satellite platforms.
3. Krypton propellant provides high specific impulse and low cost, with outstanding cost advantages, suitable for high total impulse and constellation satellite scenarios.
