PURPOSE:To provide a momentum measuring equipment for measuring the momentum involving three-dimensional positional variation through the use of GPS signal. CONSTITUTION:A GPS control section 201 calculates the latitude, longitude and altitude at current position based on a GPS signal received from a satellite at the antenna section and then delivers positional information to a main control section 204. The main control section 204 preserves the positional information, received through an interpreting/processing section 301, at a positional information preserving section 303. A momentum operating/processing section 302 calculates a momentum based on the current position information received from the section 302 and the previous positional information preserved at the section 303 and then preserves the calculation results at a momentum preserving section 304. Upon depression of a display key 104, a display processing section 305 is commanded through a key control section 203 and the section 301 to read out the momentum from the section 304 and present on a display section 102. |
