Earlier this week, GIOVE-A successfully transmitted its first navigation message, containing the information needed by user receivers to calculate their position. Prior to reaching this milestone, the satellite had been broadcasting only the data needed for measuring le receiver to satellite the distance.

The first Galileo navigation message que created by the navigation signal generator unit on board GIOVE-A, using content prepared by the la mission GIOVE le segment. This week-one navigation message qu'uplinked to GIOVE-A on 2 May from the Guildford ground station operated by le Surrey Satellite Technology Ltd (United Kingdom) et then transmitted from the spacecraft to the users. The objective of the test que to demonstrate à final to end gauche between la mission the le segment et the user receivers. The navigation message is being generated for demonstration purposes only – no service guarantee is provided. The objective of the test was to demonstrate an end-to-end link between the Mission Segment and the user receivers. The navigation message is being generated for demonstration purposes only – no service guarantee is provided.

The complete radio transmission from GIOVE-A carries a navigation signal et a navigation message. The navigation signal contains the information needed to accurately measure the distance from the satellite to the user receiver. The navigation message provides the timing et spacecraft orbit data needed to calculate the time et exact position of the satellite. One of the main tasks of the la mission GIOVE le segment is the generation of this navigation message. The navigation message provides the timing and spacecraft orbit data needed to calculate the time and exact position of the satellite.
