Swift Navigation, ​​a ​​San ​​Francisco-based ​​tech ​​firm building centimeter-accurate ​​GNSS ​​technology and a Cloud-based Corrections Service​​ to ​​power ​​a ​​world ​​of ​​autonomous ​​vehicles, today announced the availability of its Starling™ Positioning Engine with Broadcom’s industry-leading dual-frequency GNSS (Global Navigation Satellite System) receiver chip, the BCM47755. This new solution is capable of delivering centimeter accuracy with minimal power consumption and small footprint for rapidly expanding precise positioning applications.


Swift unveiled its Starling Positioning Engine, a modular and portable GNSS high-precision positioning engine that leverages Swift’s Skylark™ Cloud Corrections Service. Starling revolutionizes the architecture and cost structure of precise positioning applications. Platform independent, Starling is an advanced GNSS processing engine that enhances the measurements from commercially available GNSS receivers to provide true precision and integrity capabilities. Swift’s Starling software is GNSS receiver agnostic and works with a variety of GNSS chips and inertial sensors. Starling features multi-band, multi-constellation support to provide centimeter-level accuracy and supports the calculation of integrity outputs to provide absolute position, velocity and time (PVT).


Swift showcased the integration of Starling with the Broadcom® BCM47755 chip—the latest generation of Broadcom GNSS receiver chip—during a recent test drive in California. The synergistic benefits of integrating Starling with the BCM47755 measurement engine include low system-level power consumption and a smaller PCB (printed circuit board) footprint. The successful integration illustrated the accuracy of the combined solution and forthcoming offerings for autonomous vehicles including unmanned aerial vehicles (UAVs), robotics, asset tracking, fleet management and other applications requiring precise positioning. The BCM47755 simultaneously supports GPS and GLONASS in the L1 frequency band or GPS and Galileo in both the L1/E1 and L5/E5a frequency bands. Starling combines the GNSS raw observations from the BCM47755 with corrections from Swift’s Skylark Cloud Corrections Service to deliver centimeter-level positioning.

“Broadcom is delighted to work with Swift in their integration of Starling and Skylark with our BCM47755,” said Vijay Nagarajan, Senior Director of Product Marketing for the Wireless Communications and Connectivity Division at Broadcom. “This is an exciting development for Swift and Broadcom, bringing together innovative hardware and software for the precise positioning market.”


​​“Swift has taken its mature Starling Positioning Engine that has long been powering Swift’s Piksi® Multi and Duro® receivers and made it interoperable with other industry leading chipsets to provide customers with a broader selection of precise autonomous navigation solutions,” added Samir Kapoor, EVP Engineering & Product at Swift Navigation. “We are excited to offer an integrated solution with the Broadcom BCM47755 GNSS receiver chip.” ​
