Lockheed Martin SBAS leverages GPS and Galileo
Lockheed Martin has developed a satellite-based augmentation system (SBAS), which uses signals from the GPS and Galileo constellations, according to a report by Space News.
The second-generation SBAS uses both GPS L1 and L5 and Galileo E1 and E5 signals to provide accurate navigation and positioning and to reduce dependence on just one system. The SBAS broadcasts on two frequencies to augment the signals from both GPS and Galileo.

In September 2022, Lockheed Martin won a $1.18 billion 19-year contract to develop and operate the Southern Positioning Augmentation System Network (SouthPAN) for Australia and New Zealand. The company is also having discussions with other potential international customers.
As a part SouthPAN, the dual-frequency multiple constellation SBAS signal is being broadcast. As more GPS III and GPS IIIF satellites are launched, including one Jan. 18, service will continue to improve.
