Apparatus for on-board management of communications in a mobile node comprising a communications system configured to effect wireless data communication between said mobile node and another node by means of at least one supported wireless communications link, wherein said apparatus comprises a node manoeuvre planning module and a dynamic route planner, said node manoeuvre planning module being configured to: - identify that a wireless communications link associated with said mobile node i. has been lost, degraded or is otherwise not optimal, and/or i. would violate an emissions control restriction; - define a desired wireless communications link between said mobile node and said other node to I. support wireless communications therebetween, and/or II. comply with said emissions control restriction; - determine an attitude and/or position of said mobile node with respect to said other node required to support said desired wireless communications link; - derive a node manoeuvre plan including data representative of said determined attitude and/or position of said mobile node and generate a plan metric in respect of said node manoeuvre plan; and - transmit node manoeuvre plan data to said dynamic route planner, wherein said node manoeuvre plan data is configured to cause said dynamic route planner to derive a route plan designed to manoeuvre said mobile node to said determined attitude and/or position; said dynamic route planner being configured to: - in response to receipt of said node manoeuvre plan data, generate a route plan designed to manoeuvre said mobile node to said determined attitude and/or position and generate corresponding route plan data; and - provide said route plan data and data representative of said plan metric to a node authority with a request for authorisation. - identify that a wireless communications link associated with said mobile node i. has been lost, degraded or is otherwise not optimal, and/or i. would violate an emissions control restriction; - define a desired wireless communications link between said mobile node and said other node to I. support wireless communications therebetween, and/or II. comply with said emissions control restriction; - determine an attitude and/or position of said mobile node with respect to said other node required to support said desired wireless communications link; - derive a node manoeuvre plan including data representative of said determined attitude and/or position of said mobile node and generate a plan metric in respect of said node manoeuvre plan; and - transmit node manoeuvre plan data to said dynamic route planner, wherein said node manoeuvre plan data is configured to cause said dynamic route planner to derive a route plan designed to manoeuvre said mobile node to said determined attitude and/or position; said dynamic route planner being configured to: - in response to receipt of said node manoeuvre plan data, generate a route plan designed to manoeuvre said mobile node to said determined attitude and/or position and generate corresponding route plan data; and - provide said route plan data and data representative of said plan metric to a node authority with a request for authorisation.
