Jammer resilient UWB communication system

A system, comprising:

• a plurality of ultra-wideband (UWB) anchors configured to broadcast UWB timing data in a plurality of data packets, wherein each data packet is associated with a preamble code;
• and
• a device, including:
• a first radio controller configured to communicate with the plurality of UWB anchors using a first protocol;
• a pseudo random number generator configured to generate a pseudo random output value based on an input data value;
• and

• provide the input data value to the pseudo random number generator to cause the pseudo random number generator to output the pseudo random output value;
• determine, using the pseudo random output value, the preamble code;
• process at least one data packet of the plurality of data packets received using the first radio controller and from a first UWB anchor in the plurality of UWB anchors using the preamble code to generate a processed data packet;
• and
• determine a location of the device using the processed data packet;
• wherein when the device is not time synchronized to the plurality of UWB anchors and the processor is configured to:
• determine a first preamble code out of a plurality of preamble codes, wherein the plurality of preamble codes is determined by the first protocol;
• repeatedly use the first preamble code to attempt to decode ranging initiation messages or ranging synchronization messages received from the plurality of UWB anchors;
• and
• upon successfully using the first preamble code to decode a first ranging initiation message or ranging synchronization message, determine a current preamble hopping state value of the plurality of UWB anchors.
