Skylark Options

Skylark is available in a variety of formats to meet the specific needs and requirements of your application. Skylark is an ever-expanding service and is scalable to service billions of users. 






Enhancing Applications

Skylark DGNSS delivers high-precision location data to increase productivity of modern corporate and consumer applications, specifically mobile handsets and Internet of Things (IoT). Improving accuracy enables customers to benefit from improved mapping, targeted advertising and other location-based services (LBS) without requiring changes to the existing hardware, code base or installed application.


The DGNSS Difference

Skylark DGNSS is ideal for small, battery powered devices with size constrained antennas. It offers a low power, lightweight method to improve accuracy and is not dependent on continuous, strong carrier phase signal tracking. Skylark DGNSS offers a substantially reduced data receipt and processing burden on the system compared to RTK.


Easily Integrated

Corrections from Skylark DGNSS are easily integrated into your current platform and have been tested and validated with industry-leading GNSS chipsets. Skylark DGNSS offers a portable client library for integration into the original equipment manufacturer (OEM) domain and provides DGNSS MSM1 corrections in RTCM format.

Lane-Level Accuracy

Skylark delivers the high-accuracy performance that autonomous vehicles require, enabling ADAS, V2X and Autonomous Driving use cases that require lane-level positioning. Swift’s accuracy enables a vehicle to determine accurate position, velocity and orientation, enabling the system to initialize and validate the estimates.

Skylark is available with an integrity option for the most demanding safety-of-life critical applications. When used with Swift’s Starling positioning engine, Skylark is capable of delivering Protection Levels (PL) down to 1.5 m and Target Integrity Risk (TIR) down to 10-7 / hour. Skylark supports automotive functional safety standard ISO 26262 (ASIL B).

Seamless Corrections

Skylark provides seamless coverage across the globe—currently available in the United States, Europe, South Korea, Japan and Australia. Skylark processes positioning observations in the cloud, eliminates dependencies on baseline length and negates concerns about base station switching.



Highest Performance

Skylark RTK provides an integer-fixed RTK solution that delivers accuracy levels down to two centimeters, for optimal performance applications like agriculture GNSS-assisted steering systems, robotic and other machine-control applications.


Leverage Swift’s Network

Traditional single-base RTK solutions rely on one reference station to deliver positioning corrections for applications. Skylark RTK leverages observations from hundreds of GNSS reference stations across continents to calculate and deliver the highest-accuracy RTK solution—via the cloud—to your devices in your operating location.


Instant Access

Skylark RTK provides instant access to RTK corrections and eliminates the need for any local base station setup. All that is required is a cellular modem to access the Skylark RTK cloud-based correction service. Simply sign-up online, activate your account and start receiving Skylark corrections over the Internet via NTRIP protocol.
