Problem
definition
|
|
|
|
|
Compute Radio
Frequency (RF) attenuation for weather-sensitive
|
|
|
Satellite
Communications (SATCOM) links, on a global basis, with
|
|
|
|
emphasis on
ocean areas
|
|
|
| |
Past approach
|
|
|
|
|
Design
the SATCOM system to handle expected worst-case
weather
|
|
|
|
Use
climatology to estimate weather parameters of concern
|
|
|
|
|
Use empirical
models, based on climatological data and long-
|
|
|
baseline
observations of signal strength, to model RF attenuation
|
|
|
| |
Current
research
|
|
|
|
|
Operate
the SATCOM system based on expected daily weather
|
|
|
|
(mitigate rain
fades)
|
|
|
|
|
Use Numerical
Weather Prediction (NWP) and satellite-derived
|
|
|
observational
data to estimate weather parameters
|
|
|
|
|
Adjust
attenuation models by assimilating recorded signal strength
|
|
|
observations
