Galaxy

No more compromises

Lidar Systems

Galaxy is the next generation of airborne solutions, packing more power and accuracy into a tiny footprint than any other sensor. Designed for everything from wide-area mapping to corridor surveys, Galaxy is truly a universal sensor that rivals larger systems with its ultra-dense data and industry-leading measurement precision and accuracy.

Galaxy’s new PulseTRAK™ and SwathTRAK technologies (patents pending) make surveying simpler than ever before by providing unique innovative feature sets that maximize productivity, increase information content and reduce overhead costs.

Whether installed in a tactical UAV, integrated in a helicopter pod for powerline surveying, or gyro-stabilized with an orthometric camera for wide-area mapping, Galaxy’s performance and capability is out of this world.

A breakthrough in
collection efficiency


Features & Benefits

  • PulseTRAK technology replaces conventional multi-pulse technologies for high PRFs at high altitude
  • SwathTRAK technology moves collection efficiency to a whole new level by dynamically modifying the scan field of view during collection to maintain fixed swath widths and even point distribution, even in variable terrain
  • 2 MHz effective PRF provides on-the-ground point density and efficiency formerly reserved for dual-beam sensors
  • Industry-leading data precision and accuracy for the highest-quality datasets possible
  • Up to 8 returns per pulse provide increased vertical resolution of complex targets without the need for full waveform recording and processing (waveform recorder optionally available)
  • Fully programmable scanner enables dramatic point density increases at lesser FOVs
  • Industry-leading discrete timing electronics for pulse pair separation (i.e. minimum target separation distance) of less than 0.7 m (or less with optional waveform recorder)
  • Wide dynamic range enables exceptional small-target detection capability and capture of even the smallest details
  • In-air lidar point cloud display for maximum collection confidence
  • Real-time XYZI point clouds in LAS format enable immediate data deliverables
  • Low power requirements and compact form factor provide maximum platform flexibility
  • Tight integration with PhaseOne medium-format aerial camera systems provides excellent application flexibility and scalable solutions, and additional data deliverables
  • Production-focused workflow software with automated calibration and boresight capability using rigorous least squares methods and robust bundle block adjustment for both lidar and camera within a single workflow, enabling truly coincident datasets and quantified accuracies

The G2 Sensor System

Teledyne Optech’s new G2 sensor system for the ALTM Galaxy is the perfect solution for doubling your collection efficiency and productivity on those really large survey projects.

Designed specifically for the USGS 3DEP lidar program collections, the G2 sensor system enables efficiency and resolution comparable to FLASH lidar while maintaining independent range measurement and superior data fidelity.

Leveraging the compact form factor of the award winning ALTM Galaxy, the G2 sensor system​​ combines two Galaxy sensor heads and a 150MP camera over a standard 19" aircraft sensor portal.


All the Features and Benefits of the ALTM Galaxy, ×2!

High Productivity — Reduce Your Collection Times in Half!

  • The unique compact form factor of the ALTM Galaxy enables maximum configuration flexibility with a new option to install two sensors into a single aircraft portal, and/or fly separately for smaller jobs.
  • Maintain all the unique Galaxy feature sets of SwathTRAK™ and PulseTRAK™ to stay ahead of your competition.
  • With a doubling of the effective sampling rate, the G2 sensor system enables lidar point densities rivalling that of much more expensive FLASH lidar systems, but with the ease of collection, processing and data quality found only in a linear-mode lidar sensor.

Superior Data Fidelity

  • Maintain the high measurement confidence possible only from independent range measurement (no data averaging required).
  • Eight discrete returns with eight intensity measures.
  • Superior smooth surface repeatability.

Ease of Use

  • Using your existing Optech workflows, plan and control both sensors via a single flight and mission management system.
  • Single production workflow that processes, calibrates, co-registers and outputs survey-grade LAS files from both sensors, simultaneously.
