Abstract
Methods and devices for coding and communicating geographical position. The sending device quantizes the geographical coordinate system and sends its position as the delta or remainder after quantization. The receiving device determines its own quantized position and disambiguates between possible quantized coordinate positions of the sending device to identify the sending device's actual quantized coordinate position. From this, the receiving device determines the position of the sending device using the identified actual quantized coordinate position and the delta position data sent by the sending device. The receiving device may then trigger an action based on the determined position of the sending device.
