Embodiment Construction

[0071] exist Figure 5 In the illustrated embodiment, the method according to the invention comprises the following steps:

[0072] - Establishing [16] an approximate estimated position of the terminal. The approximate estimated position may be derived using assisted GNSS methods, wherein the positioning system derives the approximate position of the cell in which the mobile terminal is moving. This can be equivalently derived from the initial position of the terminal,

[0073] - estimate[17] the position of the satellites of each constellation (e.g. GPS and Galileo),

[0074] - deriving a list of satellites visible to the terminal from the approximate position of said terminal and said satellite positions,

[0075] - deriving [18] the elevation and azimuth angles of each satellite in the list of satellites visible to the receiver from the approximate position of the terminal,

[0076] - Classify the satellites in the visible satellite list by:

[0077] Construct [19] N g...

Abstract

The present invention relates to a method of optimization of processing of signals from satellite positioning systems in the case where at least two satellite systems cohabit and are utilized to obtain the position of a receiver. One of the systems is given preference on the basis of a criterion of performance and the satellites of the other systems are eliminated that are situated at an azimuth / elevation angle difference less than a threshold relative to the satellites of the preferred system.

Description

technical field [0001] The invention relates to a method for optimizing the processing of signals from a satellite positioning system in the presence and use of two satellite systems at the same time. By satellite positioning system is meant a system of the GPS (Global Positioning System), Galileo or Glonass type. Background technique [0002] In satellite positioning systems using GNSS (Global Navigation Satellite System) type receivers such as GPS or Galileo receivers, the data signals used by the receiver to calculate the position come from different satellites (at least four to determine the four unknowns x, y, z and t). Those skilled in the art know that positioning with such a system requires two types of processing in the receiver. [0003] The first consists in acquiring signals from at least four satellites and the second consists in estimating the distance from the receiver to the satellite from which the signal was received. The interface between the Radio Navi...
