Description

Maximum Productivity for Wide-Area, Mountain, Urban, and Corridor Survey Applications

The new ALTM Galaxy T2000 is the ultimate wide-area lidar sensor, offering best-of-class density performance and collection efficiency. It delivers the highest quality data sets to meet rigorous USGS lidar standards. With a 6500 m AGL collection envelope and a 2-MHz “on-ground” collection rate, Galaxy is simply the highest-performance sensor on the market in the smallest form factor, ensuring maximum application and platform flexibility.

Whether gyro-stabilized or fixed-mounted, high-altitude or low, one camera or six, one Galaxy or two, the Galaxy T2000 excels in all application areas with unmatched configuration flexibility, while providing the highest data precision and accuracy available.

Applications

• Wide-area mapping
• Urban mapping
• Natural resource management
• Engineering & infrastructure modeling
• Powerline & transportation corridor

Key Features

The Galaxy T2000 includes an innovative set of lidar technology enhancements that significantly increase sensor performance and collection efficiency, improve data quality, and greatly simplify the collection process.

1. Continuous Operating Envelope

PulseTRAK™ technology eliminates data coverage gaps and irregular point density commonly found with other multipulse-equipped sensors.

• Enables consistent point density with no more receiver “blind” zones.
• Complete collection freedom irrespective of terrain variability enhances efficiency.
• Greatly simplifies mission planning.

2. Dynamic Field of View (FOV)

SwathTRAK™ technology maintains fixed-width swaths, even in varying terrain heights.

• Maintains regular point distribution and improves point density consistency despite changes in terrain height.
• Fewer flightlines for maximum collection efficiency.
• 40-70% collection cost savings, depending on terrain variability, over fixed-FOV sensor designs.

3. Real-Time Sensor Protocol

Real-time sensor protocol enables in-air target observation and collection monitoring.

• Real-time XYZi point display for true-coverage verification over the entire operating envelope.
• In-air target detection and monitoring confirm small target detection, such as powerlines, in real-time.
• Real-time LAS file generation for immediate data deliverables.

4. High-Performance Scanner

A high-performance galvanometric scanner boosts performance, reliability, and data quality.

• Improves XY point distribution at higher PRF sample rates.
• Enables faster aircraft velocities and wider scan FOVs.
• Includes built-in roll compensation for clean, straight data swaths over ground.
