Abstract: The present invention relates to a system for detecting ambiguities in a satellite signal for the GPS tracking of vessels, which includes: a GNSS receiving unit obtaining a vessel position using a plurality of satellites; a vessel position calculating unit calculating a second vessel position from a first vessel position after a specific amount of time elapses using dead-reckoning; a distance calculating unit calculating prediction distances between each of the satellites and the vessel and an error monitoring unit comparing the calculated prediction distances between the satellites and the vessel, and pseudoranges between the satellites and the GNSS receiving unit at the second vessel position, and monitoring for the occurrence of errors at the satellites on the basis of the existence of an increase in errors at each of the satellites.

Abstract: The present invention provides an inertia test apparatus for a model ship that mimics a pitching inertia radius of an actual ship by reciprocating a model ship. The apparatus includes a base frame providing a supporting force, vertical frames integrally fixed at both sides of the base frame and having a hinge shaft on an upper end, a swing including a pair of fixing members rotatably hung on the hinge shafts of the vertical frames and a bed integrally formed at a lower ends of the fixing members, and providing a pitching inertia radius of the model ship by reciprocating about the hinge shafts, with the model ship seated on the bed, and a centering adjuster seating the model ship on the bed of the swing and matching a center of gravity of the model ship with a center of the swing by allowing the model ship to move.
