Abstract
Abstract A selective call receiver transmission system for transmitting a message to at least one selected selective call receiver of a plurality of selective call receivers comprises a transmitter for transmitting information including the message thereto. At least one satellite receives the information and transmits the message to the selective call receiver and subsequently retransmits the message from a different location to the selective call receiver.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
76 words
A satellite communications system for transmitting information to a receiver, comprising: transmitter means for transmitting the information; and processor means for calculating first and second locations; satellite means for, subsequent to calculating the first and second locations, receiving and retransmitting the information to the receiver from the calculated first location, and for increasing the probability of the information being received by the receiver by subsequently retransmitting the information to the receiver from the calculated second location.
Claim 2
Dependent Claim
76 words
A satellite communications system for transmitting information to a receiver, comprising: transmitter means for transmitting the information; and processor means for calculating first and second locations; satellite means for, subsequent to calculating the first and second locations, receiving and retransmitting the information to the receiver from the calculated first location, and for increasing the probability of the information being received by the receiver by subsequently retransmitting the information to the receiver from the calculated second location.
Claim 3
Dependent Claim
16 words
The satellite communications system according to claim 1 wherein the satellite means comprises a single satellite.
Claim 4
Dependent Claim
29 words
The satellite communications system according to claim 1 wherein the satellite means comprises a first satellite for retransmitting the information and a second satellite for subsequently retransmitting the information
Claim 5
Dependent Claim
36 words
The satellite communications system according to claim 3 wherein the transmitter means transmits data to the satellite means indicating the location of the receiver, the satellite means determining when the subsequent retransmission is to be made.
Claim 6
Dependent Claim
19 words
The satellite communications system according to claim 3 wherein the second satellite receives the information from the first satellite.
Claim 7
Dependent Claim
67 words
A selective call receiver transmission system for transmitting a message to at least a selected one of a plurality of selective call receivers, comprising: transmitter means for transmitting information including the message; and satellite means for receiving the information and transmitting the message from a first location to the selective call receiver and subsequently re-transmitting the message from a different calculated location to the selective call receiver.
Claim 8
Dependent Claim
67 words
A selective call receiver transmission system for transmitting a message to at least a selected one of a plurality of selective call receivers, comprising: transmitter means for transmitting information including the message; and satellite means for receiving the information and transmitting the message from a first location to the selective call receiver and subsequently re-transmitting the message from a different calculated location to the selective call receiver.
Claim 9
Dependent Claim
91 words
A satellite system for increasing the probability of a plurality of signals from a transmitter being received by a plurality of receivers, comprising: at least one satellite for receiving the signals from the transmitter and effecting first and second transmissions for each of the signals from first and second locations respectively; and programming means coupled to the at least one satellite for determining the first and second locations of each signal transmission by timing the transmission of the plurality of signals with respect to the angle of incidence at the receivers.
Claim 10
Dependent Claim
91 words
A satellite system for increasing the probability of a plurality of signals from a transmitter being received by a plurality of receivers, comprising: at least one satellite for receiving the signals from the transmitter and effecting first and second transmissions for each of the signals from first and second locations respectively; and programming means coupled to the at least one satellite for determining the first and second locations of each signal transmission by timing the transmission of the plurality of signals with respect to the angle of incidence at the receivers.
Claim 11
Dependent Claim
24 words
The satellite system according to claim 7 wherein the transmitter transmits data to the at least one satellite indicating the first and second locations.
Claim 12
Dependent Claim
89 words
In a satellite system for increasing the probability of a signal being received by a receiver from a transmitter, the method comprising the steps of: transmitting at a first time the signal from the transmitter to at least one satellite; transmitting at a second time the signal from the at least one satellite in a first location to the receiver; determining a second location from which the second transmission will be made; and re-transmitting at a third time subsequent to the second time the signal from the second location.
Claim 13
Dependent Claim
89 words
In a satellite system for increasing the probability of a signal being received by a receiver from a transmitter, the method comprising the steps of: transmitting at a first time the signal from the transmitter to at least one satellite; transmitting at a second time the signal from the at least one satellite in a first location to the receiver; determining a second location from which the second transmission will be made; and re-transmitting at a third time subsequent to the second time the signal from the second location.
Claim 14
Dependent Claim
25 words
The method according to claim 9 further comprising the step of transmitting data to the at least one satellite indicating the first and second locations.
Claim 15
Dependent Claim
68 words
A satellite system for increasing the probability of a signal being received by a receiver from a transmitter, comprising: at least one satellite for receiving the signal from the transmitter and effecting first and second transmissions; and programming means coupled to the at least one satellite for determining first and second points in time in which the at least one satellite effects the first and second transmissions, respectively.
Claim 16
Dependent Claim
68 words
A satellite system for increasing the probability of a signal being received by a receiver from a transmitter, comprising: at least one satellite for receiving the signal from the transmitter and effecting first and second transmissions; and programming means coupled to the at least one satellite for determining first and second points in time in which the at least one satellite effects the first and second transmissions, respectively.
Claim 17
Dependent Claim
26 words
