Positioning and Orientation equip-ment M990 (Adopt Trimble BD990)

With the updating of measurement technology and with the more and more demand of the measuring accuracy. The previous GPS posi-tioning equipment and GPS orien-tation equipment already cannot meet the requirement for measuring. And the higher accuracy positioning and orientation equipment is needed to replace the old ones.

M990 RTK positioning and orientation 

equipment which is new released has the technical features with high precision, signal stabilization, wide operating range, etc. Get the favor of the new and old customers.
