Hovermap ST is a SLAM-based multi-use mobile LiDAR scanning solution capable of survey-grade mapping and georeferenced point clouds with autonomous functionality.

Hovermap ST (SLAM) Simultaneous Localization and Mapping

Hovermap ST Improves accuracy for common mapping tasks and, with GCP, can be used to create survey-grade scans for long, linear assets or feature-poor environments that have previously been challenging for other SLAM-based systems.

A compact design

The compact and lightweight design makes it easy to carry when scanning on foot and offers longer flight time when used on a drone.

Survey-grade control & georeferenced point clouds

Hovermap ST’s precision engineering, Emersent’s world-class Simultaneous Localization and Mapping (SLAM), and automated ground control feature provide dense, shadow-free, survey-grade point clouds of entire assets. Ground control also automatically georeferences point clouds to survey control.

Weather Resistant

The rugged, weather-resistant, IP65-rated Hovermap is dust and splash-proof, so you can create maps in harsh environments, rain or shine. Hovermap’s resistance to moisture makes it ideal for use in underground mines.

Autonomous Tap-To-Fly

Hovermap ST’s Tap-To-Fly feature allows exploration of previously inaccessible areas beyond the line of sight and communication range and access to unprecedented insights from a tablet. Omnidirectional collision avoidance, guided exploration, and smart Return-to-Home capabilities ensure assets remain safe and valuable equipment is not damaged or lost.

Hovermap ST transmits a live point cloud to the Hovermap app and previews the data in real-time as it is collected within communication range. That way, you can exit the site knowing you’ve captured everything you need.

Autonomy Levels

Mobile Mapping Mode

Mapping mode provides fast, accurate, high-resolution mobile scanning of environments where drone autonomy is not necessary. In addition, Hovermap ST’s quick-release mechanism allows you to easily switch from a drone to handheld scanning.

Pilot Assist Mode

Pilot Assist Mode offers omnidirectional collision avoidance, GPS-denied flight capability and stability control, providing confidence and stability for accurate and thorough inspections. It acts as a safety bubble for your drone, protecting the asset and your equipment.

Autonomous Waypoints

Autonomous Waypoint Mode enables beyond-line-of-sight flights through Smart Waypoints and guided exploration. Just tap on the map to set smart waypoints, and Hovermap ST will take care of the rest, navigating to the waypoints and mapping the area while keeping itself and the drone safe from obstacles.
