Two real-time reference stations are set up at two locations, each broad-

casting on a different channel.

If the signal from one reference station is jammed, the channel can be

changed and the other reference can be used.

Set up as in case 1.

Two separate fixes for each point can be obtained, providing redundancy for

future least squares adjustment operations.

If the signal is blocked due to radio interference, the channel at the reference

and the rover can be changed in order to work on a slightly different

This option is not available for RX1250 with SmartAntenna.
