Laser Measurements Without a Pole and Operation in Challenging Conditions

Meridian M20L is equipped with a modern green laser with a working range of up to 100 meters, allowing precise measurements on hard-to-reach or hazardous objects without the need for physical access to the point.

This opens new possibilities for:

• surveying bridges, supports, and piles,
• work near water bodies,
• measurements at height,
• operation in restricted-access areas,
• industrial and municipal facilities,
• energy infrastructure facilities,
• combined indoor and outdoor measurements.

The green laser remains clearly visible even in bright daylight, making fieldwork more comfortable and efficient.

High-Precision GNSS RTK with IMU Tilt Compensation

Meridian M20L supports all modern satellite systems and signals:

• GPS
• GLONASS
• Galileo
• BeiDou
• QZSS
• SBAS
• NavIC
• PPP (Galileo HAS and BeiDou)

The receiver is equipped with 1408 GNSS channels, ensuring stable signal reception even in challenging urban environments, under trees, or near obstacles.

RTK positioning accuracy:

• Horizontal: ±(8mm + 1ppm)
• Vertical: ±(15mm + 1ppm)

The 200 Hz IMU module provides fast and accurate tilt compensation without calibration. Tilt compensation accuracy reaches up to 2 cm even when the survey pole is tilted up to 60°.

4G, Wi-Fi, Bluetooth, and Integrated Radio

Meridian M20L supports modern wireless communication technologies for maximum compatibility with field equipment and RTK correction networks.

Communication modules:

• 4G LTE modem
• Bluetooth SPP + BLE 5.0
• Wi-Fi 802.11 a/b/g/n/ac
• Integrated UHF Radio 410–470 MHz

Supported formats and protocols:

• RTCM 2.X / 3.X
• CMR / CMR+
• NMEA-0183
• RINEX

With data update rates up to 20 Hz and signal reacquisition in less than 1 second, the receiver delivers stable performance even in dynamic conditions.

Compact Design, Powerful Battery, and IP67 Protection

Meridian M20L features a compact palm-sized housing and weighs only 699 grams, making it convenient for everyday field use.
