Laser Technology

Mars’ precise green laser, visible in the daylight, allows to measure points where it’s impossible to stand with a range pole. The combination of the GNSS receiver and laser distance meter, fits ideally well with surveyors’ work and increase significantly the productivity.

IMU

Mars boasts a 3rd generation built-in IMU sensor that detects minute accelerations from the laser point or range pole. Using advanced algorithms, it can maintain high precision with tilt compensation up to 120° in laser mode, simplifying field surveying and eliminating manual initialization

New K8 Platform

Featuring 1590 channels and the ability to track more than 60 satellites, Mars is not just versatile, but also efficient by supporting SBAS PPP services. With its capability to achieve fixation within seconds, it significantly enhances productivity

Enhanced UHF

The integrated UHF transceiver module, built into the Mars device, boasts an impressively long operational range of up to 15 kilometers. Mars offers flexibility by allowing users to freely switch between rover and base modes
