ASR specializes in the design and manufacture of innovative survey systems. 


Our differential barometers/altimeters (patent pending) provide accurate readings corrected for natural deviations in atmospheric pressure. 

Forward Rate of Growth (FROG) sensors (patent pending) incorporate this technology to provide real-time data on conditions at the head of an active wildfire front where it is normally too dangerous for firefighters to work.

We are based in Whitehorse, Yukon Territory, Canada.
