1. A multiplatform system comprising a plurality of networked nodes that communicate over a netted data link, wherein at least some of the nodes are configured to:

  • transmit a coded waveform at one or more scheduled times for receipt by one or more of the other nodes;

    correlate coded waveforms received from the other nodes to estimate a range to at least some of the other nodes; and

    reset a navigational error and revise a trajectory based on the range estimates to the other nodes to avoid a possible collision with one or more of the other nodes.
