A mobile reception experiment of Galileo improved I/NAV navigation messages

Abstract (in Japanese) (See Japanese page) 
(in English) In satellite positioning, both the reception of ranging signals and the acquisition of navigation messages are necessary. In general, the acquisition of navigation messages does not always require the reception of radiowaves; however, when radiowaves are used for acquisition, a period of continuous reception significantly longer than one second is required. The European satellite positioning system, Galileo, started broadcasting new navigation messages from August 2022. The improvement is based on a secondary synchronization pattern, secondary forward error correction, and reduced ephemeris to aid in the rapid recovery from interruptions in message acquisition caused by temporary deterioration in radio reception. This report evaluates the recovery characteristics from interruptions in navigation message acquisition by moving reception of this improved I/NAV navigation message.
