Embodiment Construction

[0065] The present invention will now be described in conjunction with specific embodiments. The specific examples help to provide a better understanding to those skilled in the art, but are not intended in any way to limit the scope of the invention, which is defined by the appended claims. In particular, embodiments described independently throughout this specification may be combined to form other embodiments within the scope of not mutual exclusion.

[0066] In order to understand the problems solved by some embodiments of the present invention, figure 1 Schematically shows satellite 30 in geostationary orbit ( figure 1 marked "Earth orbit") around the Earth.

[0067] Satellite 30 receives an uplink signal from ground station 60 ( figure 1 labeled "uplink") (for example, voice or data to be relayed toward another point on Earth). Furthermore, due to, for example, a mis-pointed satellite dish (i.e., a mis-pointed antenna) or because the radiation pattern of the antenna ...

Abstract

An observation satellite used to obtain information on electromagnetic energy emitted from Earth. The satellite orbits the earth with an inclination greater than 90° and less than 270°. In addition, the observation satellite includes at least one receiving antenna having a receiving pattern directed toward the earth and adapted to operate at radio frequency while the satellite is orbiting relative to the earth's surface Receive electromagnetic energy within range. The observation satellite also includes a transmitter configured to at least one of: (i) retransmit at least a portion of the received electromagnetic energy, (ii) transmit information representative of at least a portion of the received electromagnetic energy , (iii) transmitting information derived from at least a portion of the received electromagnetic energy. The invention also relates to related systems and methods.

Description

technical field [0001] The present invention relates generally to telecommunications and obtaining information related to electromagnetic energy emitted from one or more sources on Earth. The invention may be used, for example, to locate sources of interference on Earth, but the invention is not limited to this particular application. Background technique [0002] Satellite communications particularly involve the transmission of signals from stations on Earth to satellites and vice versa. Satellite communications can be used to provide communication services between two points on Earth, including point-to-point services (such as the Internet, satellite telephony) and point-to-multipoint (broadcast) services (such as television). Stations performing satellite communications may be fixed (eg, rooftop dishes) or mobile (eg, vehicles, ships, aircraft, handheld devices). As the use of satellite and terrestrial communications increases, so does the risk of interference between t...
