Node configured to determine ownship position information and/or ownship time information without transmitting two-way timing and ranging (TWTR) signals

A method, comprising:

• listening, by a node comprising at least one radio and at least one processor, to a first two-way timing and ranging (TWTR) interrogation message and a first TWTR response message communicated between a first pair of nodes during a first time interval, wherein the first TWTR interrogation message indicates position information and optionally time information of one node of the first pair of nodes, wherein the first TWTR response message indicates position information and optionally time information of another node of the first pair of nodes;
• based at least on the first TWTR interrogation message and the first TWTR response message, determining, by the node, a first time difference of arrival (TDoA) between the first TWTR interrogation message and the first TWTR response message for the first pair of nodes;
• based at least on the first TDoA between the first TWTR interrogation message and the first TWTR response message, determining, by the node, a first boundary of position (BoP);
• based at least on the first BoP, determining, by the node, position information of the node and optionally time information of the node without the node transmitting any TWTR interrogation message and without the node transmitting any TWTR response message;
• and
• based at least on at least one of the position information of the node or the time information of the node, at least one of (a) outputting, by the node, instructions to adjust communication parameters, (b) outputting, by the node, instructions to adjust operational parameters of at least one of at least one sub-system or at least one sensor of the node, (c) outputting, by the node, instructions to display at least one graphical image including information of the at least one of the position information of the node or the time information of the node, (d) outputting, by the node, instructions to navigate the node, (e) outputting, by the node, instructions to communicate with at least one node, (f) authenticating, by the node, position information obtained from at least one navigation system, (g) authenticating, by the node, time information obtained from at least one time system, or (h) outputting, by the node, instructions to the at least one node to support controlling communications with the node through the at least one node.
