1. A method of autonomous operation of an earth moving machine (EMM) configured for shoving matter, said EMM comprising at least one implement operatively connected to a mission computer, the method comprising:

  • (a) receiving, by the mission computer, a mission objective;

    (b) obtaining mapping data in respect of a mission area;

    (c) determining, with help of a positioning utility, a position of said EMM in respect of said mission area;

    (d) determining a mission execution route, based on at least said mapping data and said mission objective, said mission execution route comprising one or more segments within said mission area, wherein each segment is associated with a disposal point;

    (e) calculating, for each of said one or more segments, with the help of the mission computer, an implement trajectory of said at least one implement along said segment, thereby enabling accumulation of matter by said at least one implement along said segment as said EMM progresses, and disposing of said accumulated matter upon arrival at said disposal point, wherein said calculating is based on at least the mission objective, the mapping data, a length of said segment and shoving capability data of said EMM, and wherein the accumulating load on the EMM is not greater than the maximal shoving capability of the EMM; and

    (f) operating said EMM along said mission execution route and repositioning said implement while operating said EMM along at least one of said one or more segments according to said implement trajectory.
