Walking route determination unit, method, and program

A walking route determination method comprising:

• determining, by an environmental value determinerc based on a plurality of satellite signals from a plurality of satellites received by a positioning apparatus held by a pedestrian of object, an environmental value indicating whether a reception environment of a satellite signal of the plurality of satellite signals is good or bad for a left half side and a right half side with reference to a traveling direction of the pedestrian;
• and
• comparing, by a route determiner, an environmental value of the left half side determined by the environmental value determiner with an environmental value of the right half side determined by the environmental value determiner to determine a walking route of the pedestrian.

A computer-readable non-transitory recording medium storing a computer-executable program instructions that when executed by a processor cause a computer system to:

• determine, by an environmental value determiner based on a plurality of satellite signals from a plurality of satellites received by a positioning apparatus held by a pedestrian of object, an environmental value indicating whether a reception environment of a satellite signal of the plurality of satellite signals is good or bad for a left half side and a right half side with reference to a traveling direction of the pedestrian;
• and
• compare, by a route determiner an environmental value of the left half side determined by the environmental value determiner with an environmental value of the right half side determined by the environmental value determiner to determine a walking route of the pedestrian.
