20090043503 | Method and Device for Determining Protection Levels for Satellite Navigation Systems - A method and apparatus for determining protection levels in a satellite navigation system includes the following steps: (1) determining an integrity risk at the alert limit for a plurality of application situations—for example, starting from approaches in category I (Category I precision approach) up to the operation “oceanic enroute;” (2) determining an interval of the alert limits between the largest set of alert limits which produces too high an integrity risk, and the smallest set of alert limits which produces an acceptable integrity risk; and (3) carrying out an interval nesting for the interval of the alert limits that was determined in the previous step, the integrity risk between the horizontal and the vertical being divided in the same way as it is obtained from the relationship between these integrity risks in the largest set of alert limits. | 02-12-2009 |
20090284410 | Vehicle System And Earth-Based Receiver System - In a vehicle, a vehicle system is provided that includes a position determination module for determining the position of the vehicle using an estimation of the error of satellite signals which are received by an earth-based receiver system, and an integrity module for determining an integrity risk for the position data for a vehicle, the risk being derived using time determinations performed by a satellite navigation system. When a threshold value for the integrity risk for the position data is exceeded, the vehicle system generates a warning signal which, by means of modules that are connected to the vehicle system, is designed to prevent the use of the position data for the vehicle. The integrity risk is determined using an estimated value for the error in the received satellite signal, and the receiver system functionally interacts with a plurality of satellites to determine and transmit data to a vehicle system containing a position determination module for determining the position of the vehicle. | 11-19-2009 |
20100052979 | METHOD AND APPARATUS FOR THE OPTIMIZATION OF STATUS MESSAGES IN A SATELLITE NAVIGATION SYSTEM - In a method for optimization of status messages in a satellite navigation system, which comprises a space segment having a plurality of satellites that emit navigation signals to be received and evaluated by utilization systems for position determination, and a ground segment having a plurality of observation stations that monitor the satellites, a threshold value is determined, as a function of location, for a message indicating that the error of a satellite is no longer acceptable. | 03-04-2010 |

20130271315 | Enhancement of the Integrity Concept of a Satellite Navigation System - A method for determining the integrity risk at an alert limit of a position solution determined with a satellite navigation system involves calculating a first integrity risk at the alert limit assuming that one satellite j of the satellites is faulty. A first position solution is determined with the signals from all of the satellites and a second position solution is determined with the signals from all of the satellites except for the signal received from the satellite j. A difference between the first and the second position solution is identified and subtracted from the alert limit to create a reduced alert limit. A second integrity risk at the reduced alert limit is calculated with the signals received from all satellites except the signal received from the satellite j. The integrity risk at the alert limit is determined using the minimum of the first and second integrity risks. | 10-17-2013 |
20130273955 | Generation of a Data Stream Comprising User Messages in a Satellite-Based Augmentation System - In a satellite-based augmentation system a data stream is generated that includes user messages having different message types. A plurality of predetermined unique sequences of message types are formed and each formed sequence is allocated to one of a plurality of data sources that are used for generating user messages in the satellite-based augmentation system. A data source is selected for generating a data stream that includes user messages. The selected data source generates the data stream including user messages by using the predetermined unique sequence of message types that is allocated to the selected data source. | 10-17-2013 |

20090289840 | Process for Optimizing Status Notifications in the Case of a Navigation Satellite System - A process for optimizing status notifications in the navigation satellite system includes the following steps: the determination of information concerning a communication network of the navigation satellite system; and the transmission of the determined information as a status notification in at least one navigation message. | 11-26-2009 |
20100141511 | Method for Increasing the Availability of a Global Navigation System - A process for increasing the availability of a global navigation system that includes a plurality of spacecraft, each of which transmits information for determining the position of a terminal. From the plurality of spacecraft, a first subset, with at least one spacecraft, and a second subset are determined. the second subset being constituted by those spacecraft that are not included in the first subset. The integrity risk is determined for the information transmitted only by the second spacecraft. The first and the second subsets of spacecraft are determined such that the integrity risk, for information transmitted by the second subset spacecraft minimized relative to the integrity risk for information of all spacecraft included in the plurality of spacecraft. | 06-10-2010 |

20080288167 | Method and Apparatus for Providing Integrity Information for Users of a Global Navigation System - In a method for providing integrity information for users of a global navigation system, which comprises several space vehicles like satellites transmitting information to a device for position detection, the transmitted information comprises first information from the global navigation system about the accuracy of a signal in space error SISE of a faulty space vehicle, and second information whether or not the global navigation system assesses the faulty space vehicle as faulty. The invention is based on the assumption how exact a fault can be detected, so that performance the global navigation system can be increased; and no unfounded assumption is used which improves the quality of service. | 11-20-2008 |

20130023205 | Satellite-Based SAR Services - A satellite-based SAR system having a space segment with a plurality of satellites and a ground segment with one or a plurality of ground stations is provided. A satellite receives a position report from an emergency transmitter in its service area and forwards it to a ground station. The ground segment stores the position of the emergency transmitter, received with the last position report, in a management system for emergency transmitters. The emergency transmitter sends position reports to the satellite such that the reception of position reports at the satellite is coordinated such that at any time only position reports arrive which differ with regard to their signal parameters such that simultaneous reception is possible. A rescue operation is initiated for the emergency transmitter if no deactivation message has been received from the emergency transmitter and no position report is received from the emergency transmitter within a specified period. | 01-24-2013 |
20130033398 | COMBINED USE OF DIFFERENT SATELLITE NAVIGATION SYSTEMS - Method, arrangement and system for improving a combined use of a plurality of different satellite navigation systems, in which each of the plurality of different satellite navigation systems includes a constellation of at least one satellite. The method includes broadcasting from each satellite of the constellation of a first satellite navigation system the clock models for all satellites of the constellation of a second satellite navigation system. | 02-07-2013 |
