SimCom’s GNSS modules now integrated with Swift’s Skylark service

Swift Navigation and SimCom are partnering to deliver centimeter-level GNSS accuracy to high-volume robotics applications worldwide. The collaboration integrates Swift’s Skylark precise positioning service with SIMCom’s high-performance SIM66MD and SIM66D GNSS modules.
This combination allows manufacturers and developers using these modules to activate centimeter-accurate satellite positioning, dramatically improving the performance, safety and reliability of robotic lawnmowers, delivery robots, agricultural vehicles, and other autonomous systems. SIMCom’s GNSS modules have compact designs, low power consumption, and wide array of interfaces, making them suitable for seamless integration into diverse IoT and autonomous devices.
Swift’s Skylark Nx RTK, the highest precision variant of Skylark, leverages a proprietary atmospheric model to deliver continuous 1-2 cm accuracy across vast geographic areas, including all of Western Europe. The carrier-grade network eliminates the need for developers to manage base stations or switch between multiple correction providers, simplifying deployment of high-precision outdoor robots at scale.
Key benefits for autonomous navigation:
- Autonomous Operation. Centimeter-level accuracy is essential for robots to execute complex tasks, such as following precise mowing patterns, planting seeds with exact spacing, or navigating narrow construction sites.
- Safety and Geofencing. Precise localization enables reliable enforcement of virtual boundaries (geofencing), preventing robots from entering restricted zones or colliding with obstacles, which is critical for safety in public or shared spaces.
- Improved Efficiency. Reliable 1-2 cm precision reduces path errors, minimizes overlap in coverage (e.g., in farming or lawn care), and ensures the robot consistently reaches its exact target destination, maximizing battery life and operational uptime.
Customers purchasing SIMCom’s SIM66MD and SIM66D modules now receive a six-month free trial of Skylark Nx RTK.
