Customer satisfaction is our major goal. See what our customers are saying about us.

I am used to work mostly in challenging ground terrains with hills and heavy canopy and CORSnet RTK service has greatly enhanced my work speed and productivity. 24 x 7 customer support from CORSnet team has been one of the best experience I had.

I was mostly used to Total Station Survey till I experience CORSnet powered GNSS RTK surveying technology. Now I find CORSnet service is very productive and easy to use technology. CORSnet professional team provides excellent support and they are very friendly and available anytime. Their field support is superb.

Have been using SULECO CORS Network for last couple of years in our field operations and found to be very reliable and dependable. We could complete many of our tasks even before the expected targets due to the support received from CORSNET. Wherever you go and whatever you do in Sri Lanka, positioning will be assured with CORSnet.
