Abstract: A portable phone unit for use in satellite communication systems has a vertically correcting antenna module pivotally secured to the handset for free rotation about a pivot axis. The module contains a mechanism, such as a gravitational counterweight for urging the module to pivot into a predetermined vertical orientation regardless of the handset orientation. An antenna projects from the module in a direction which is vertically upright when the module is in its predetermined vertical orientation. A mast mounted antenna module can also be used to take advantage of dissimilar antenna segment weights for multiple frequency antennas. As the handset is moved into an angular orientation, the module pivots under the weight of the counterweight, or a portion of the antenna itself, until the antenna is oriented vertically.

Abstract: The present invention relates to a method and a system of controlling the gain input into an antenna of a gateway. Based on the obtained antenna elevation a path gain is calculated. Together with the obtained transponder gain and the obtained antenna dish gain the path gain is used to calculate a common gateway gain. This common gateway gain is used to adjust the gain a variable gain amplifier.

Abstract: A system and method for controlling the strength of a shared resource signal transmitted by the satellite transponder in a satellite communications system. The satellite communications system includes a gateway for transmitting communications signals including a shared resource signal, a satellite transponder for relaying the signals to at least one subscriber unit (for example, a phone), and at least one subscriber unit for receiving the signals. The method includes the steps of receiving the shared resource signal, at each subscriber unit, via the satellite transponder; measuring, at each subscriber unit, a signal strength for the received shared resource signal; sending the signal strengths to the gateway; and adjusting the power of the shared resource signal transmitted by the satellite transponder based on the signal strengths.

Abstract: A quadrifilar antenna is comprised of four radiators which, in the preferred embodiment, are etched onto a radiator portion of a microstrip substrate. The microstrip substrate is formed into a cylindrical shape such that the radiators are helically wound. Also etched onto the microstrip substrate is a feed network that provides 0 DEG , 90 DEG , 180 DEG and 270 DEG signals to the antenna radiators. The feed network utilizes a combination of one or more branch line couplers and one or more power dividers to accept an input signal from a transmitter and to provide therefrom the 0 DEG , 90 DEG , 180 DEG and 270 DEG signals needed to drive the antenna. For receive operations, the feed network utilizes these same components to receive the 0 DEG , 90 DEG , 180 DEG and 270 DEG signals from the antenna radiators and to provide a single output signal to a communications receiver. The power divider accepts an input signal and provides therefrom two output signals differing from each other in phase by 180 DEG . The branch line coupler accepts an input signal and provides therefrom two output signals differing from one another in phase by 90 DEG .
