The present invention provides a self-adhesive prepreg which is characterized by comprising: a base prepreg that is composed of reinforcing fibers and a thermosetting resin composition (I), some or all of which is impregnated into a reinforcing fiber layer that is formed of the reinforcing fibers; an adhesive layer that is composed of a nonwoven fabric which is laminated on at least one surface of the base prepreg so as to be integrated with the base prepreg and a thermosetting resin composition (II) which is laminated on the surface of the nonwoven fabric so as to be integrated with the nonwoven fabric.

Self-adhesive prepreg and method for producing same

A navigation apparatus utilizing a global positioning system having at least first and second satellite reception antennas installed on a navigation vehicle with a predetermined distance therebetween, a first azimuth computing unit for computing a first azimuth angle of the navigation vehicle from satellite radio waves received at the first and second antennas and a phase difference therebetween, a second azimuth computing unit for computing a second azimuth angle from a time change of antenna positions calculated from the satellite radio wave received at the first or second reception antenna, first and second multiplying units for multiplying outputs of the first and second azimuth computing units with predetermined coefficients respectively, an adding unit for adding outputs of the first and second multiplying units to produce a third azimuth angle, and a coefficient control unit for varying coefficient values of the first and second multiplying units in accordance with either the satellite arrangement or turning frequency of the navigation vehicle.
