Abstract: |
Accurate planning of forthcoming missions requires an accurate knowledge of diffuse sources
in order to optimize mission parameters and the scanning strategy.
Zodiacal Light (ZL or Zody) is a well known contaminant for ground based and space-borne observations
and contributes to determine the limit magnitude of a survey.
Despite the physical origin of ZL is well known,
predicting and modeling Zody contamination is complicated by a number of subtleties.
The cloud of
Interplanetary
Dust Particles has a quite complex 3D structure, whose main geometrical
parameters have been assessed in the last two decades, but their photometrical properties
are affected by a significant level of uncertainty.
The observer orbiting the Sun is moving
within the cloud of IDPs, leading to an important time dependence in the
perturbing signal and asking for a precise knowledge of the expected trajectory and scanning strategy
of the mission.
This work illustrates this problem taking the ESA Euclid mission as
a case study and presenting the Zody EUclid Simulator (ZEUS) developed for this mission. |
