SatLab SL7 GNSS Receiver
Description
The SatLab SL7 GNSS Receiver is a compact and lightweight high-precision GNSS RTK receiver designed for professional surveying, mapping, and geospatial data collection. Equipped with an advanced GNSS chipset and a high-performance antenna, the SL7 provides stable centimeter-level positioning even in challenging environments such as urban areas, dense vegetation, or complex terrain.
The receiver supports simultaneous tracking of multiple satellite constellations including GPS, GLONASS, Galileo, and BeiDou, increasing satellite availability and improving positioning reliability. It features up to 1408 GNSS channels, ensuring robust signal tracking and strong resistance to interference.
One of the key innovations of the SL7 is its integrated HD starlight camera, which enables visual stakeout with Augmented Reality (AR) through the SatSurv Survey Software platform. This allows surveyors to locate target points visually in the real environment, improving efficiency compared to traditional stakeout methods.
The SL7 is also equipped with a 200 Hz IMU sensor, enabling tilt compensation up to 60° without requiring manual calibration. This allows accurate measurements even when the survey pole is tilted, significantly improving productivity in the field.
With its rugged design, lightweight body (approximately 750 g), and extended battery life of up to 24 hours, the SL7 provides excellent portability and reliability for long surveying sessions.
The receiver is ideal for various geospatial applications, including:
-
Land and cadastral surveying
-
Topographic mapping
-
Construction and engineering surveys
-
GIS data collection
-
UAV ground control point (GCP) surveys
-
Hydrographic surveys
-
Precision agriculture
