Friends, Here is some more information about the Galileo test satellite extracted from the latest SSTL briefing ....... The E5 channel is 1164-1215 MHz and the L1 channel is 1559-1591 MHz. The website has received spectrum pictures. ( for interest.... those of you with grey beards, and/or thinning hair, will recall that the 25m Chilbolten dish mentioned below was activated by Ian, G3SEK, on 432 MHz many, many years ago) 73 Peter G3LTF " Europe's first Galileo navigation signals were transmitted from space by the GIOVE-A satellite at 17:25 GMT this afternoon 12th January. The satellite payload was commanded 'on' from the SSTL Mission Control Centre and the Galileo signals were successfully received using the 25-metre dish antenna at Chilbolten (Andover) and the ESA Station in Redu (Belgium). The Galileo E5 and L1 channel signals were successfully decoded at the SSTL groundstation using a Galileo navigation receiver. On Monday 9th January, the on-board atomic clocks and signal generating systems were checked by the SSTL Mission Control Centre and found to be performing nominally. An ESA team then travelled to the Chilbolten groundstation in the UK to prepare to analyse the first Galileo signals to be transmitted from the GIOVE-A satellite. The different modes of Galileo signals will now be generated sequentially using the GIOVE-A first payload chain to perform the frequency filing activities. Once these frequency filing activities are completed (expected by the end of January 2006), the payload commissioning will resume with the checkout of the second and third payload chains, assumed to be performed by mid-February 2006. Additional measurement campaigns will then be carried out to assess the Medium Earth Orbit (altitude of 24,000 kilometres) radiation environment, characterise the performance of on-board clocks and perform signal-in-space experimentations."
