Real GIOVE-A mission commencing imminently
The main objective of GIOVE-A is to secure the frequency filing for the Galileo satellite navigation system with the ITU (International Telecommunication Union), which is fundamental to the operation of the Galileo project and a crucial first stage in the development schedule.
The payload will be switched on today (Tuesday 10th) or tomorrow so that the first of the two frequency bands can be tested. SSTL are running on schedule, so the operators have a few days spare time if required before the planned payload start.
The payload is operated as a single unit that will start transmitting the various signals at about the same time.
The ITU rules dictate that once the satellite is transmitting, there cannot be a break in transmission for more than 4 months. For this reason, the GIOVE-B satellite will provide a back-up system once launched to ensure that these crucial frequencies are secured.
