Based on Airbus DS Products’ heritage in the development of HiRel space GNSS receivers, the LION 1000 generation navigation receiver series delivers high performance supporting both multiple frequency reception and multiple navigation constellation operation. The cutting-edge new series takes benefit from advances in navigation processing technology, as well as from upgrades of the GPS constellation - now providing more civil signals - and from Galileo entering its operational phase. Therefore, LION 1300, the first member of the Product family, is designed to make use of the GPS signals L1, L2C, and L5 and of the Galileo signals E1, E5a, as well as Glonass and Compass open signals.
