Teledyne Optech ALTM Galaxy PRIME

Compact, high-performance lidar sensor provides industry-leading collection efficiency and point density in all terrains

The new Galaxy PRIME is the next evolution of the popular Galaxy wide-area/corridor lidar mapping platform that incudes the advanced and unique PulseTRAK and SwathTRAK productivity feature sets. An innovative “boost mode” increases range performance, and an expanded range of motion for the dynamic FOV used by SwathTRAK ensures that the Galaxy PRIME is quite simply the most versatile, highest-performing, and most productive sensor on the market.

Description

The new Galaxy PRIME is the next evolution of the popular Galaxy wide-area/corridor lidar mapping platform that incudes the advanced and unique PulseTRAK™ and SwathTRAK™ productivity feature sets. An innovative “boost mode” increases range performance, and an expanded range of motion for the dynamic FOV used by SwathTRAK™ ensures that the Galaxy PRIME is quite simply the most versatile, highest-performing, and most productive sensor on the market, no matter the type of terrain you survey. Coupled with its compact form factor, the Galaxy PRIME offers maximum application and platform flexibility.

Core to Galaxy PRIME is a significant increase in collection efficiency — as much as 50% over competing fixed FOV sensors —when using Galaxy PRIME's SwathTRAK technology. SwathTRAK dynamically adjusts the Galaxy’s scan FOV in real time during data acquisition, enabling fixed-width data swaths and constant point density, even in highly variable terrain — effectively enabling you to survey steep mountains as if they were flat! The result is far fewer flightlines to collect and process, and a consistent point distribution whether on hill peaks or valley bottoms — in fact, the steeper the terrain, the greater the project cost savings.
