Description

Maximum Productivity for Survey Applications

The new ALTM Galaxy PRIME+ is the ultimate wide-area lidar sensor,
with best-of-class collection efficiency, smallest form factor, and highest quality data sets
to meet rigorous USGS lidar standards. Now with a 6500m AGL collection envelope and
1-MHz “on-ground” collection rate, Galaxy is quite simply the most productive sensor available
with the lowest SWaP for maximum application and platform flexibility.

Whether gyro-stabilized or fixed-mounted, high-altitude or low, one camera or six,
full waveform or discrete, Galaxy PRIME+ 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

1. Continuous Operating Envelope

PulseTRAK™ technology enables a truly continuous operating envelope by eliminating
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 significantly enhances efficiency.
• Greatly simplifies mission planning.

2. Dynamic Field of View (FOV)

SwathTRAK™ technology is the only sensor to incorporate a real-time dynamic FOV that
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. Boost Mode

This feature enables enhanced range performance and maximum detectability, day or night, when applications demand it.

• Improved range performance
• Improved small target detection
• Improved vegetation penetration

4. Real-time Sensor Protocol

Galaxy incorporates a real-time sensor protocol to enable in-air target observation and collection monitoring,
significantly increasing collection confidence.

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

5. High-Performance Scanner

A new, high-performance galvanometric scanner forms the foundation of Galaxy’s exceptional performance capability.
Featuring extremely high torque and minimal electrical inductance, the new scanner provides superior scan speeds
at reduced voltages for a significant boost in performance, reliability, and scan linearity.

• Improves XY point distribution at higher PRF sample rates.
• Enables faster aircraft velocities and wider scan FOVs.
• Increases point density at lesser FOVs.
