･ GPS is operated by the U.S. Department of
Defense. The department controls the
accuracy of the system, and manages the
system. Therefore, GPS radio wave
condition may be controlled (degradation of
accuracy, suspension of radio wave
transmission, etc.) at the discretion of the
U.S. Department of Defense.
･ Some wireless communications products
(mobile phone, data detectors and some
others) block satellite signals and also
causes instability of signal reception.
･ Some map displays based on location
information (latitude/longitude information)
may be not accurate due to some countries'
or regions' regulations.

it may be difficult to receive radio waves in
