Frequently Asked Questions
How is Skylark different from other GNSS corrections services?
Skylark’s superiority stems from its advanced modeling of atmospheric errors. This model uses observations from strategically placed ultra high quality reference stations that are built and operated in partnership with mobile network operators.
While other services simply manage access to a network of individual local stations, Skylark integrates data from all its stations working together, enhancing the accuracy and reliability of its corrections, and dramatically extending its coverage.
Skylark’s robustness has led it to be the first cloud-based real-time service of any kind to be ISO certified for automotive functional safety.
What level of accuracy can I expect from the Skylark service?
Skylark is available in three variants ranging in accuracy from 2 cm to 1 m while balancing coverage, power consumption, and cost across to meet the full range of requirements of location-based applications.
Do I need to install my own RTK base station?
No, Skylark utilizes a network of ultra high quality Continuously Operating Reference Stations (CORS) around the world to model corrections in the cloud so that you do not need to install your own.
Do I need specific hardware to use Skylark?
Skylark is hardware agnostic and supports a wide variety of GNSS receivers from industry-leading manufacturers. Look up your receiver to check its compatibility with Skylark or contact us to discuss your specific requirements.
Do I need an internet connection to receive corrections?
Yes, a GNSS receiver needs to be connected to the Internet to receive correction data from Skylark.
