Variables include: Duration of INS only / GNSS onlyPositions on the flight path at GNSS loss / INS saturationINS / GNSS performance characteristicsInvestigation 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 JammingSelf generated noise (electronic components)Thermal (Johnson–Nyquist) noiseComparison of various GNSS Receivers to identify most suitable candidate, accounting for: SurvivabilityOperating RestrictionsSignal Acquisition StrategyNoise MitigationsGuidance 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 forcesDevelopment of autopilot functionality, trajectory calculations and comparison, corrective manoeuvre calculation.TPBN1_UKTJ
