1. A tracking system for determining a location of a vehicle, comprising:

  • a sensor configured to determine a first coordinate value that represents a location point of said vehicle; and

    a translation mechanism configured to receive said first coordinate value and to translate said first coordinate value into a translated value by mathematically combining said first coordinate value with a second coordinate value, said second coordinate value representing another location point, said translation mechanism further configured to transmit said translated value to a monitoring mechanism over a wireless channel of a communication network, said monitoring mechanism configured to track said vehicle based on said translated value, wherein said translation mechanism is configured to translate said first coordinate value such that said translated value is defined by a smaller number of data bits than said first coordinate value thereby reducing a number of data packets transmitted by said translation mechanism and said communication network to inform said monitoring mechanism of said vehicle location point.
