The Proximity Operations Evaluation Tool (POET) is a software solution developed by Dstl that supports the planning and optimisation of satellite manoeuvres during close-proximity operations in space.
It enables users to design safe and efficient manoeuvres using simple inputs, without requiring specialist expertise. As space missions become more complex and existing tools remain difficult to use or are not tailored to these operations, POET offers a more accessible and effective approach to mission planning.
Satellites are increasingly required to operate in close proximity to other spacecraft for activities such as inspection, repair, refuelling and debris removal. These operations are highly complex, as satellite movement is difficult to predict and strict safety constraints must be maintained.
Planning these manoeuvres typically relies on expert teams and can be both time-consuming and costly. While existing tools are powerful, they are not designed specifically for planning Rendezvous, Proximity Operations, and Docking (RPOD) manoeuvres. This makes them difficult to use and limits accessibility.
At the same time, the number of satellites in orbit is increasing rapidly. This is creating a growing need for faster, more scalable and easier-to-use solutions to support the planning of complex satellite manoeuvres.
POET simplifies the planning of satellite manoeuvres by allowing users to define and simulate movements using straightforward inputs. The tool performs the required calculations in the background, removing the need for specialist expertise.
POET adopts a modular approach, enabling users to build, adjust and refine manoeuvres step by step.
Users can monitor key parameters throughout the process, including position, velocity and fuel usage.
POET supports trajectory optimisation, enabling the design of fuel-efficient manoeuvres.
Outputs can be visualised or exported for further analysis, supporting greater insight and flexibility in mission planning.
Proximity operations involve manoeuvring a satellite close to another object in space for activities such as inspection, servicing or debris removal.
POET is used to design, simulate and optimise satellite manoeuvres during close-proximity missions.
POET enables users to design manoeuvres using simple inputs, removing the need for specialist expertise.
POET can support missions involving Rendezvous, Proximity Operations, and Docking (RPOD), as well as servicing, debris removal and constellation management.
