Andrews Land Surveying performs GPS (Global Positioning Services) surveying services throughout Maryland, Delaware and federal projects in the District of Columbia. GPS surveying can provide a position (Latitude, Longitude and Height) directly, without the need to measure angles and distances between intermediate points. We use two types of GPS surveying:

• Static GPS surveying is a relative positioning technique which employs two (or more) stationary receivers simultaneously tracking the same satellites. One receiver, the base receiver, is set up over a point with precisely known coordinates.
• Real-time kinematic (RTK) positioning is a satellite navigation technique used to enhance the precision of position data derived from satellite-based positioning systems such as GPS.

You can trust Andrews Land Surveying to provide accurate GPS surveying. The turnaround time and cost of a our GPS services may vary due to observation time required to complete the job. Give us a call today to learn more!
