Small and lightweight design
High performance
Fast initialization
Calibration-free IMU
Compatibility with a variety of GNSS software platforms

Edit Content

The L2 is a lightweight and compact GNSS receiver with IMU, making it ideal for a variety of surveying and mapping applications. It is the smallest geodesic GNSS device in the world so far, with a weight of less than 170g.

Despite its size, the L2 is fully equipped with all the necessary components, including a high-performance OEM board and 1408 channels. This allows it to support all satellites and frequency bands, and to perform exceptionally well even in complex environments.

The L2 also features a fast initialization, calibration-free, and immune to magnetic interference IMU module. This allows users to collect or stakeout topo points up to 60 degrees, without the need for any additional calibration.

The L2 is compatible with a variety of GNSS software platforms, such as SurPro, Field Genius, and SurvCE. This makes it easy to integrate into existing workflows.

The L2 is a versatile and powerful GNSS receiver that is well-suited for a wide range of applications, including:

Land surveying
GIS industry
Pipeline measurement
Construction
Agriculture
Mining
Forestry
