Function
This command creates a duplicate of the satellite with the given satID using the provided
multipath parameters. The parameters include the Range Offset, Range Change, Range
Interval, Doppler Offset, Doppler Change, Doppler Interval, Power Offset, Power Change
and Power Interval.
The final optional satID can be used to specify which existing satellite is to be replaced by
the newly created duplicate. If this satID is not provided, and there are no free channels,
the command will fail, and produce an error.
Note
Multipath satellites require 60 seconds to be created and are introduced at modulo 30
second intervals. The GSG can only introduce 4 duplicate satellites at a time and at a max-
imum rate of one satellite every two seconds. Multipath, SBAS and interference/jamming
channels cannot be the duplicated. This command is only available when the scenario is run-
ning. Note that excessive changes to Range or Doppler may result in Doppler shifts greater
than the system can handle and cause the satellites to shutdown due to exceeding the
hardware capabilities.
