Problems solved by technology

In such an event, the possibility exists that the mobile terminal may interfere with other satellites in Earth arc orbits adjacent to the target satellite with which the mobile terminal is communicating
[0004] It is also recognized that Fixed Service Satellite (FSS) operators may have difficulty locating interference from VSAT (Very Small Aperture Terminal) systems comprising simple terminals at thousands of remote sites

Embodiment Construction

[0014] Referring to Figure 1, there is shown a system 10 for implementing the preferred method of the present invention. System 10 provides data content to and from multiple mobile platforms 12a-12f in one or more different coverage areas 14a and 14b. System 10 generally includes ground segment 16 , a plurality of satellites 18 a - 18 f forming space segment 17 , and mobile terminals 20 disposed on each mobile platform 12 . Mobile platform 12 may include an aircraft, a pleasure boat, or any other moving vehicle. Therefore, the exemplification of the mobile platform 12 as an aircraft in the figures herein and the reference of the mobile platform as an aircraft in the following description should not be construed as limiting the applicability of the system 10 to aircraft only.

[0015] Space segment 17 may include any number of satellites 18 in each coverage area 14a and 14b needed to provide coverage for each area. Satellites 18a, 18b, 18d and 18e are preferably Ku or Ka band...

Abstract

A system and method for quickly detecting and remedying an interference incident caused by one of a plurality of mobile terminals in communication with a transponded satellite. The method makes use of a time line constructed from communications of each of the mobile terminals. The time line forms a real time, sequential record of events wherein various mobile terminals have made contact with the transponded satellite . The methods extrapolates from the time line which one of the mobile terminals has caused an interfering event by determining which mobile terminal accessed the communication system just prior to the interference even arising.

Description

[0001] This application claims priority to Provisional Application No. 60 / 281,356, filed April 4,2001. technical field [0002] The present invention relates to a mobile RF terminal required for two-way communication with a base station via a satellite link, and in particular to a method for identifying which of a plurality of mobile terminals is causing a problem for one or more adjacent satellites in orbit. Method and apparatus for jamming satellites. Background technique [0003] With mobile RF terminals located on mobile platforms such as aircraft, cruise ships, and other mobile platforms that communicate with ground stations via repeating satellites, although there are security devices that can be built into mobile terminals, there is still an extremely small possibility that the terminal malfunctions in unexpected ways. In such an event, there is a possibility that the mobile terminal may interfere with other satellites adjacent to the target satellite with which the ...
