The SF10C and SF11C altimeters are lightweight short range (100-120m) laser altimeters which can be used on our Arducopter-based UAS. They improve hovering and landing accuracy and the logged values may be retrieved for post flight data analysis. At this time we are not actively using these systems on our UAS fleet, but they remain in our sensor inventory. Please contact us if you would like more information.
