1. A system for evaluating an environment, said system comprising:
- (a) a first magnetic field sensor to sense a first component of a magnetic field in a first direction;
(b) a second magnetic field sensor to sense a second component of said magnetic field in a second direction normal to said first direction;
(c) a third magnetic field sensor to sense a third component of said magnetic field in a third direction normal to said first and said second directions;
(d) a first accelerometer to sense a first acceleration in said first direction;
(e) a second accelerometer to sense a second acceleration in said second direction; and
(f) a processing unit responsive to a program instruction to measure said first, said second and said third components of said magnetic field, said first acceleration, and said second acceleration and determine a compass direction from said measured components of said magnetic field and said measured acceleration.

3. A system for evaluating an environment comprising:
-
(a) a position sensing unit capable of sensing a direction and a distance when said position sensing unit is moved from a location to another location; and (b) a processing unit responsive to a program instruction to record an output of said position sensing unit when said position sensing unit moved from a first location to a second location and when said position sensing unit is moved from said second location to a third location and to determine an ambit of a tract defined by said first, said second and said third locations. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10)

11. An apparatus for evaluating an environment, said apparatus comprising:
-
(a) a first magnetic field sensor outputting a first magnetic field datum in response to a component of a magnetic field acting in a first direction; (b) a second magnetic field sensor outputting a second magnetic field datum in response to a component of said magnetic field acting in a second direction normal to said first direction; (c) a third magnetic field sensor outputting a third magnetic field datum in response to a component of said magnetic field acting in a third direction normal to said first direction and said second direction; (d) a first accelerometer outputting a first acceleration datum in response to acceleration in said first direction; (e) a second accelerometer outputting a second acceleration datum in response to acceleration in said second direction; (f) a memory arranged to store a program instruction and a datum; and (g) a processing unit responsive a program instruction to determine a compass direction from said first, second and third magnetic field data and said first acceleration datum and said second acceleration datum. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
