ALTM Gemini

Product catalog summary

Introduction
The ALTM Gemini is the latest addition to the ALTM family, offering enhanced capabilities for base mapping. It maintains the performance of the ALTM 3100EA while allowing higher altitude operations at peak repetition rates, making it ideal for base mapping needs. Key features include intensity capture with a large dynamic range for high-quality lidar imagery.

Technological Advancements
The ALTM Gemini features revolutionary multipulse technology, enabling users to double conventional operating altitudes without compromising data density compared to single-pulse systems. It boasts an effective pulse repetition rate of 167 kHz and advanced inertial technology to maximize mapping efficiency.
