Modern Guidance Schemes for the Terminal Area Energy Management (TAEM) Flight
Title:
Phase of Reusable Space Transportation Systems
To develop and validate novel guidance approaches and algorithms for the TAEM flight regime, which is critical for the
development of future European reusable space transportation systems, and which will be needed for preceding experimental
vehicles. During the TAEM phase, the guidance system aligns the vehicle with the runway, while controlling altitude and
velocity. The proposed activity shall improve the knowledge of the TAEM phase by analysing typical spacecraft configurations
and requirements for this phase, shall research novel guidance approaches for TAEM, which would enhance the degree of
autonomy and reusability, and which would reduce the operations costs, and shall include the testing and verification of
algorithms on a validated software platform.
Deliverables:
GNC algorithms for the Terminal Area flight phase, verified on a validated software platform; Technical Report and Technical
Notes, summarizing the analytical trades and documenting the key features and advantages of the selected guidance
approach.

Title:
Robust Multi-mission Navigator
Hybridized navigation concept, using GPS-like signals to complement IMU information as well as air data sensor, laser
altimeter/ranger and optical sensor data, is a promising solution for compensating drift errors and uncertainties of the
gravitational field. A hybridized navigation solution is being studied in the frame of the on-going TRP study on "Aeroassist
Technology for Planetary Exploration", nevertheless, some specific problems need to be investigated in details. In the light of
the above considerations, the aim of the proposed activity is to develop a European multi-mission hybrid navigator breadboard
that will be tailored for upcoming Earth entry vehicle demonstrator(s). The expected benefit is a highly integrated robust hybrid
navigator breadboard with multi-mission capabilities ready for use in future space transportation and re-entry programmes.
The hybrid navigator will exclusively be based on European technologies due to strict export control licenses on US
components. The study shall include the functional performance evaluation of three cases: launcher, aeroentry/reusable
space transportation, multi-mission hybrid navigator.
Deliverables:
Nav. Breadboard. Hybridised nav. flight SW demo. Data package / summary report / abstract, incl. nav. sensor spec,
hybridised nav. sys. prel. design, functional perform. evaluation (mentioned 3 cases); spec/baseline architecture; design; test
results.
