Bullseye™

Why Bullseye?

Determining the optimal timing and path of an interplanetary trajectory is a difficult problem. Sometimes even making an initial guess at the solution is a challenge. Yet that’s what most other in-space trajectory simulation codes require in order to converge - a priori knowledge of the solution. The advantage of Bullseye is the fact that it was designed from the outset to use a robust search algorithm to find the optimal solution even over a broad range of possibilities.

How does it work?

Bullseye combines ephemeris data with a Lambert’s solver to determine the optimal trajectory between two bodies for a given time of flight. You can choose one of two unique simulation modes. The first simulates a single interplanetary trajectory and might be useful for a cargo or robotic mission. The second combines an outbound trajectory, surface stay period, and return trajectory as would be the case in a human or sample return mission.

Bullseye utilizes a robust search routine to quickly explore a large set of potential interplanetary trajectories. Simply set your ranges for departure date, time(s) of flight, and the optional surface stay period, and execute the simulation.

Unique Features

Bullseye offers several features that separate it from the competition and make it even easier for you to get the job done right.

Eliminate candidate solutions that don’t meet your requirements by placing ranges on departure and arrival dates, time(s) of flight, surface stay periods, and allowable C3 and delta-V for each mission segment.
Add your own custom ephemeris data for objects such as asteroids to augment the default data for all eight planets and Pluto

License Information

Bullseye software is sold under an annual renewable license. The initial purchase of the software entitles the customer to one (1) year of Bullseye use, along with access to any updates or bug fixes released during that calendar year.
