Product Detail
Features
-
Multi-constellation
The L300, with its 1408 channels, new generation full GNSS chipset & ability to support multiple satellite constellations including GPS, GLONASS, BEIDOU, GALILEO, QZSS, SBAS, and IRNSS, provides precise and accurate spatial data for all users around the world. -
WiFi and WebUI
L300 serves as a WiFi hotspot, so users can easily access and manage the status, set the configuration, or download static and PPK raw data through the advanced WebUI using a computer, smartphone, or other electronic devices with WiFi support without any need for third-party software or cables. -
IMU Tilt Sensor
L300 is equipped with a fast initialization, calibration-free, & magnetic interference-immune Inertial Measurement Unit (IMU). All users can use this technology to collect or stakeout topo points up to 60°.
-
GSM & UHF radios
A fast internet connection is guaranteed with a built-in 4G module that accelerates receiving correction data using all telecommunication signals and bands. L300 comes with an integrated 15 km-range Tx/Rx internal UHF radio that ranges from 410 MHz to 470 MHz with selectable frequency, providing the ability to connect and collect accurate real-time data in base/rover mode. -
Battery & Power
L300 is delivered with an internal large-capacity 6800mAh lithium-ion internal battery supporting USB type-C fast charging, which allows users to work for more than 12 hours in daily fieldwork. -
Working mode
Every surveyor needs to operate and choose a suitable working method based on project requirements and required accuracy. In order to work in such conditions, users will need a device to be able to work in different modes such as static, network RTK, UHF RTK, PPK, & etc. The L300 is offering all you need in a package!
