Silverbird has state-of-the-art tools and capabilities for high-thrust, low-thrust, and dual-mode trajectory design. We have over a decade of experience developing trajectories that most effectively utilize the performance of advanced spacecraft propulsion systems. Our trajectory design capabilities can enable missions that could not be performed using traditional methods, or greatly reduce costs by e.g. allowing the use of smaller launch vehicles for the same payload.
A more detailed description of our trajectory design tools and methodology, with an emphasis on low-thrust trajectories, can be found here.
