Abstract: According to the present invention, a GPS reference station generates and transmits compensation information on GPS deviations for each wireless AP, and a user terminal recognizes and uses the information to compensate for information received through a GPS receiver of the user terminal, in order to deliver precise GPS performance. In particular, a precise GPS system of the present invention comprises: a GPS reference station for receiving a first satellite signal from a GPS satellite to generate navigation compensation information on a wireless AP, and transmitting the generated navigation compensation information to a wireless AP; a wireless AP for receiving the navigation compensation information from the GPS reference station, and transmitting the information to a user terminal; and a user terminal for receiving a second satellite signal from a GPS satellite, recognizing the navigation compensation information from the wireless AP, and generating precise user position information based on the second satellite signal and the navigation compensation information.

Abstract: An antenna apparatus comprises an antenna cover 120 which includes a shielding unit 110 formed on a predetermined portion of one hemispherical surface of the antenna cover. The shielding unit 110 may be formed of electromagnetic shielding material which may reflect or absorb a jamming signal. The shielding 110 may cover a range of low angle signal reception directions relative to the antenna. The shielding 110 may be in the form of a paint applied to a surface of an antenna cover. The shielding 110 may be controlled to block certain signal directions. The shielding material may be formed on or adjacent the surface of a hemispherical, electromagnetic transparent radome. The shielding may be arranged to be rotated in a vertical and/or horizontal manner to block one or more jamming signals. Also disclosed is a method for shielding an antenna, comprising: detecting if a jamming signal is present. If a jamming signal is detected, then the shielding is rotated until the jamming signal is at a receive sensitivity or less. If no jamming signal is detected then the position of the shielding is controlled such that the shielding is located in a north direction relative to the antenna. The apparatus and method provides a simple and cheap way of avoiding jamming signals.
