Laser Measurements Without a Pole and Reliable Operation in Challenging Conditions

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

This opens up new possibilities for:

• surveying bridges, supports, and piles,
• work near water areas,
• measurements at height,
• work in restricted-access zones,
• industrial and municipal facilities,
• energy infrastructure projects,
• 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 tracking even in difficult environments such as urban areas, 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 with pole inclinations of 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 a data update rate of up to 20 Hz and signal reacquisition in less than 1 second, the receiver ensures stable operation even in dynamic conditions.

Compact Design, Powerful Battery and IP67 Protection

Meridian M20L features a compact palm-sized design and weighs less than 699 grams, making it convenient for everyday fieldwork.

Key advantages:

• 7000 mAh battery,
• up to 20 hours of operation in laser RTK rover mode,
• up to 40 hours in static mode,
• USB PD fast charging support,
• IP67 dust and water protection,
• operating temperature from -40°C to +85°C,
• resistance to drops from up to 2 meters onto concrete.
