Abstract
A grid-based transmission system for determining relative positions of vehicles in a grid quadrangle of a reference grid, each vehicle having a transmitter and a receiver, comprising determining an absolute position of a vehicle. A reference grid is obtained. A reference point for the reference grid is assigned; and a relative position of the vehicle relative to the reference point is generated. The reference grid is a stored and previously generated reference grid, or is generated based on the absolute position and a transmission range of a transmitter. The vehicle sends a position message containing the relative position; the transmission range; an identity of the vehicle; an identity for all other vehicles that have previously sent a position message received by the vehicle; and the relative position of the all other vehicles.

15. A method for determining absolute positions of vehicles from their relative positions in a quadrangle of a reference grid, all vehicles having a transmitter and a receiver, the method comprising:
-
a) a second vehicle receiving a relative position message from a first vehicle; b) the second vehicle obtaining the reference grid; c) the second vehicle determining its absolute position; and d) the second vehicle assigning its own reference point in the reference grid. wherein the assigning of the reference point is dynamic. - View Dependent Claims (16, 18, 19, 20, 21, 30, 31, 34)
