Abstract
(EN)
A position determining unit has an assistance data processing and relaying module (software client) (1318) that obtains localised assistance data,such as Global Navigation Satellite Systems (GNSS) assistance data and/or non-GNSS(such as Wireless Positioning System) assistance data, from an assisting peer position determining unitand relays the localised assistance data to an assisted peer position determining unit. The relaying may be done via an assistance server. In a relaying GNSS position determining unit, such as a GPS receiver, the chip (1310) architecture has multi-frequency GNSS baseband (1311), GSM or UMTS baseband (1312) for long range communication and short range baseband (1313) such as Bluetooth or Wi-Fi or UWB. The assistance data generating module (1316) generateslocalised assistance data at the relaying GNSS unit from the GNSS R.F. front end and/or GNSS baseband and/or microcontroller running the GNSS solutions software portion. The assistance data feed module (1317) suppliesassistance data to any combination of the main modulesof the GNSS position determining unit. The supplied assistance data may originate in the relaying GNSS unit itself or the assisting GNSS unit.

L'invention concerne une unité de détermination de position qui comporte un module (1318) de traitement et de relais de données d'assistance (client logiciel) qui permet d'obtenir des données d'assistance localisée, telles que des données d'assistance de systèmes de géolocalisation et de navigation par un système de satellites (GNSS) et/ou des données d'assistance autres que GNSS (p. ex. système de positionnement sans fil) qui proviennent d'une unité de détermination de position homologue d'assistance, et de relayer les données d'assistance localisée vers une unité de détermination de position homologue assistée. Le relais peut être mis en œuvre par l'intermédiaire d'un serveur d'assistance. Dans une unité de détermination de position GNSS de relais, tel qu'un récepteur GPS, l'architecture de puce (1310) comporte une bande de base (1311) GNSS à fréquences multiples, une bande de base (1312) GSM ou UMTS pour les communications à longue portée et une bande de base (1313) à courte portée telle que Bluetooth, Wi-Fi ou UWB. Le module (1316) de production de données d'assistance produit des données d'assistance localisée à l'unité GNSS de relais, à partir du processeur frontal GNSS R.F. et/ou de la bande de base GNSS et/ou d'un microrégisseur exécutant la partie logicielle des solutions GNSS. Un module (1317) de chargement de données d'assistance fournit des données d'assistance à toute combinaison des modules principaux de l'unité de détermination de position GNSS. Les données d'assistance fournies peuvent provenir de l'unité GNSS de relais elle-même ou de l'unité GNSS d'assistance.
