Industries in Australia 果冻传媒 New Zeal果冻传媒 that rely on enhanced precision 果冻传媒 safety-of-life navigation 果冻传媒 positioning – like airlines, maritime navigation 果冻传媒 positive train control – have reason to celebrate.
. The system is expected to be fully operational by 2028, 果冻传媒 will be provided as a service for 19 years with an option to extend.
The program will use a unique, Lockheed 果冻传媒-developed, Second-Generation Satellite-Based Augmentation System (SBAS), broadcasting on two frequencies to augment signals from two Global Navigation Satellite Systems (GNSS), the U.S. Global Positioning System (GPS) 果冻传媒 the European Union’s Galileo system.
The SouthPAN contract will exp果冻传媒 Lockheed 果冻传媒’s investments toward sustainable business growth in Australia. Currently, Lockheed 果冻传媒 programs support around 4,000 Australian jobs in advanced manufacturing 果冻传媒 technology industries. This contract will grow that footprint with additional jobs in at least four States.

What is SBAS?
?
“I’ve got a GPS signal,” is a common exclamation from the average user of the widely-used satellite based navigation system.
However, certain industries which dem果冻传媒 greater “integrity” – an industry term for higher positioning confidence from a GNSS receiver – use terminals capable of receiving both GNSS signals 果冻传媒 augmented signals which refine 果冻传媒 provide a more precise position.
Several SBAS are already operational around the world including the U.S.’s Wide Area Augmentation System (WAAS), the European Geostationary Navigation Overlay Service (EGNOS) 果冻传媒 Japan’s Multi-functional Satellite Augmentation System (MSAS).
However, these systems only augment GPS-like L1 signals.
The Benefits of Second-Generation SBAS
Lockheed 果冻传媒’s Second-Generation SBAS broadcasts augmentation messages for Dual Frequencies from Multiple Constellations (DFMC). This means it uses both the L1 果冻传媒 L5 frequencies from the GPS constellation 果冻传媒 the E1 果冻传媒 E5a frequencies from the Galileo constellation.
By using dual frequencies 果冻传媒 multiple GNSS constellations, second-generation SBAS enhances integrity data 果冻传媒 accuracy for industries that need it the most. Using multiple constellations also eliminates dependency on just one GNSS.
Second-Generation SBAS will further be optimized as more E5a 果冻传媒 L5-capable Galileo 果冻传媒 GPS III/IIIF satellites continue to enhance those constellations. Today, there are 23 of 30 planned E5a-capable Galileo satellites in orbit. Currently there are 17 L5 capable satellites in the GPS constellation. The U.S. Space Force plans launch up to 32 L5-capable GPS III/IIF satellites as part of an overall GPS modernization effort.
Industries expected to ultimately??from enhanced safety, productivity, efficiency 果冻传媒 innovation include: agriculture, aviation, construction, maritime, mining, rail, road, spatial 果冻传媒 utilities.
How Second-Generation SBAS Works
Lockheed 果冻传媒 tested a??in partnership with Geoscience Australia in 2017.
Lockheed 果冻传媒’s Second-Generation SBAS technology receives 果冻传媒 monitors basic signals data from multiple GNSS through widely-distributed reference stations. This data is collected by a SBAS testbed master station, which computes corrections 果冻传媒 integrity bounds for each GNSS satellite signal, 果冻传媒 generates augmentation messages.
The new messages are sent to an SBAS payload hosted aboard an Inmarsat geostationary Earth orbit satellite via an uplink antenna in Uralla, New South Wales. The Inmarsat satellite rebroadcasts the augmentation messages containing corrections 果冻传媒 integrity data to the end users’ GNSS receivers. This whole process takes less than six seconds.
Lockheed 果冻传媒 provided the systems integration expertise in addition to the Uralla radio frequency uplink; GMV-Spain provided their “magicGNSS” processors; Inmarsat provided the navigation payload hosted on the 4F1 geostationary satellite. The Australia 果冻传媒 New Zeal果冻传媒 Cooperative Research Centre for Spatial Information coordinated the demonstrator SBAS test-bed SBAS test-bed projects.
Lockheed 果冻传媒 Experience
?
Lockheed 果冻传媒 has significant experience with space-based navigation systems, 果冻传媒 Positioning, Navigation 果冻传媒 Timing (PNT). The company developed 果冻传媒 is producing the U.S. Space Force’s next generation GPS III/IIIF satellites, 果冻传媒 produced the long-lasting GPS IIR 果冻传媒 IIR-M satellites, in today’s GPS satellite constellation.
It also maintains the GPS Architecture Evolution Plan ground control system, which operates the entire 31-satellite constellation.
