Starling Positioning Engine

High-precision positioning engine designed for automotive applications that require centimeter or decimeter accuracy using GNSS and dead reckoning sensor fusion

Starling works with a variety of GNSS chipsets and inertial sensors, making it ideal for mass-market autonomous applications. Starling’s software is written in standard C++ and runs on a variety of compute platforms. Starling utilizes the measurements from commercially available GNSS receivers to provide centimeter-accurate results with high integrity. Starling supports the calculation of precise position, velocity and time (PVT) and when combined with inertial sensor measurements, wheel odometry and other sensor inputs, Starling can assist with localization, decision and control.

    Receiver Agnostic

    Starling works with single and multi-frequency, multi-constellation automotive and commercial-grade GNSS measurement engines, offering companies a choice in selecting the best components for their autonomous sensor suite, whether in Vehicle to Vehicle (V2V) applications, automated driving systems, rail, delivery, mobile, industrial, robotics, UAS, or micromobility.

  • starling 2


    Starling has been designed for fast portability and runs on leading processors and operating systems. Through the use of industry standard protocols and application program interfaces (APIs), customer engineering investment in porting and bring-up time is minimized.

    Designed for Automotive Safety

    Starling is engineered from the ground up to comply with the automotive industry functional-safety standardISO 26262 for Automotive Safety Integrity Level (ASIL)-B safety standards. When used in combination with Swift’s Skylark precise positioning service, Starling offers industry leading Protection Levels (PL) and Target Integrity Risk (TIR).
