Intern in the Systems Department - Development of PVT Algorithms for Lunar Users

Location

ESTEC, Noordwijk, Netherlands

Our team and mission

The End-To-End Systems Engineering Division (TEC-SE) is responsible for supporting projects for the Engineering of E2E systems, the associated security aspects, E2E systems integration/verification activities (SIV), and service preparation. To serve these functions, the Head of the End-To-End Systems Engineering Division defines and executes the associated technology developments and studies, as well as the verification and validation laboratory facilities, and supports the preparation of the relevant engineering standards.

The E2E Systems Division consists of five sections and associated laboratory facilities:

• Navigation Systems Definition Section;
• Navigation Systems Implementation and Validation Section;
• Systems Security Engineering Section;
• Telecommunication Systems and Techniques Section;
• E2E System Comms Section.

The role will be within the Navigation Systems Implementation and Validation Section, which provides expert advice and engineering support to ESA projects, programmes, and studies in the fields of radio navigation and Global Navigation Satellite Systems (GNSS).

Moonlight is one of ESA's ongoing programmes, under which a Lunar Communications and Navigation System (LCNS) constellation is being developed to provide communication and navigation services for lunar environment.

The role includes advanced lunar navigation algorithms development capable of estimating a user's Position, Velocity, and Time (PVT) using measurements from a single navigation satellite orbiting the Moon. The resulting capability will support the provision of navigation services during the initial deployment phase of the Moonlight system, when only a single navigation satellite may be available before the full constellation is established.

Field(s) of activity for the internship

Advanced lunar navigation algorithms development capable of estimating PVT using measurements from a single navigation satellite orbiting the Moon.

Your tasks will include

• conducting research and developing innovative algorithm(s) for Position, Velocity and Time (PVT) estimation in the lunar environment using measurements (i.e. doppler and code) from a single Moonlight navigation satellite;
• developing, implementing and validating the PVT algorithm(s) through simulation and performance assessment activities;
• performing sensitivity analyses to assess the impact of key error sources, including satellite orbit determination and timing synchronisation (ODTS) and receiver clock errors;
• investigating and analysing the use of additional information sources available in the lunar environment, such as Digital Elevation Models (DEMs) and communication signals from the ESA Pathfinder satellite, to enhance navigation performance;
• evaluating the algorithm performance under different lunar operational scenarios, including the initial Moonlight deployment phase when only a single navigation satellite may be available.
