Analysis of the stresses and strains the one-way effector airframe will be subject to, alongside the structural performance of the airframe design and materials
Assessment of GNSS (Global Navigation Satellite System / GNSS is an aircraft satellite navigation system that provides precise position, velocity, and time data using global constellations like GPS and Galileo) signal re-acquisition time at various points in boost phase, based on previously provided ephemeris, time and position data
Monte Carlo simulations of INS (Inertial Navigation System) only and GNSS only performance across various conditions to assess impact of GNSS signal loss or INS saturation. Variables include:

Duration of INS only / GNSS only
Positions on the flight path at GNSS loss / INS saturation
INS / GNSS performance characteristics

Investigation to understand the process for how GNSS data is provided to the effector whilst at the launch location, and the intended mechanism for how effector maintains or re-acquires GNSS during the boost phase.
Investigation into the expected RF noise profile across the flightpath, accounting for:

Adversary Jamming
Self generated noise (electronic components)
Thermal (Johnson–Nyquist) noise

Comparison of various GNSS Receivers to identify most suitable candidate, accounting for:

Survivability
Operating Restrictions
Signal Acquisition Strategy
Noise Mitigations

Guidance and logic on how synchronised launches from different platforms should be planned and conducted to minimise the risk of mid air collision by effectors. Details on launch procedures for pre-authorised launch and operator launch.
Assessment of Effector re-entry angle, loads experienced, correction factors (static margin etc) in the upper atmosphere before air density becomes useful. Considerations to include:

Entry attitude, Unwanted yaw, roll-axis misalignment, aerodynamic stability, spin, aerodynamic torque, structural bending, atmospheric gusts, miscourse duration, inertial forces

Development of autopilot functionality, trajectory calculations and comparison, corrective manoeuvre calculation
Only candidates based in UK and eligible to work in UK are allowed
