System and method to determine a location of a designated position of a vehicle system

A system, comprising:

• a first sensor configured to sense a location of a reference position of a vehicle system;
• a controller comprising one or more processors that are configured to calculate a first range area in which a designated position of the vehicle system is determined to be located based at least in part on a calculated distance from the location of the reference position determined by the first sensor;
• a second sensor configured to sense a second range area in which the designated position of the vehicle system is determined to be located, wherein the second range area is determined using a global navigation satellite system (GNSS) receiver as the second sensor;
• and
• the controller being further configured to compare the first range area and the second range area and respond to an overlap or a lack of overlap of the first range area and the second range area.

A method, comprising:

• sensing a first location of a first vehicle system using a first sensor;
• adding a designated distance to the first location to identify a calculated range of potential locations of a designated position of the first vehicle system;
• obtaining a sensed location of the designated position of the first vehicle system using a second sensor;
• comparing the calculated range of potential locations of the designated position with an uncertainty range of the sensed location of the designated position to determine whether the sensed location of the designated position and the calculated range of potential locations of the designated position overlap or are within a threshold distance of each other;
• and
• identifying a safety boundary at or within a rearward most of the calculated range and the uncertainty range responsive to the calculated range and the uncertainty range overlapping each other or being within the threshold distance of each other, or identifying the safety boundary at or within the calculated range responsive to the calculated range and the uncertainty range not overlapping and not being within the threshold distance of each other.
