Systems and methods for mobile platform localization using ultra wide band (UWB) signals

A method for mobile platform localization system for a mobile platform, comprising:

• receiving, from a first beacon located external to the mobile platform, first beacon ultra-wideband (UWB) transmissions at a first ultra-wideband (UWB) sensor mounted on the mobile platform, at a second UWB sensor mounted on the mobile platform, and at a third UWB sensor mounted on the mobile platform, wherein the first UWB sensor, the second UWB sensor, and the third UWB sensor are mounted according to a non-linear arrangement;
• identifying the first beacon and generating a spatial location of the first beacon based on the first beacon UWB transmissions;
• receiving, from a second beacon located external to the mobile platform, second beacon UWB transmissions at the first UWB sensor, at the second UWB sensor, and at the third UWB sensor;
• identifying the second beacon and generating a spatial location of the second beacon based on the second beacon UWB transmissions;
• receiving, from a third beacon located external to the mobile platform, third beacon UWB transmissions at the first UWB sensor, at the second UWB sensor, and at the third UWB sensor;
• identifying the third beacon and generating a spatial location of the third beacon based on the third beacon UWB transmissions;
• and
• generating a spatial location of the mobile platform, as a function of the spatial location of the first beacon, the spatial location of the second beacon, and the spatial location of the third beacon.
