Abstract EN
Signal degradation suffered by the vehicle is a combination brownout and blackout during Mars atmospheric entry.
The communications brownout means that signal fades and blackout means that the signal is lost completely.
The communications brownout and blackout periods are analyzed and predicted with an altitude and velocity profiles.
In the brownout period, the range measurements between the vehicle and the orbiters are modeled as intermittent measurements with the radio signal arrival probabilities, which are distributed as a Rayleigh distribution of the electron number density around the entry vehicle.
A new integrated navigation strategy during the Mars atmospheric entry phase is proposed to consider the probabilities of the radio measurements in the communications brownout and blackout periods under the IMU/beacon scenario based on the information filter with intermittent measurements.
Numerical navigation simulations are designed to show the performance of the proposed navigation strategy under the integrated navigation scenario.
