GPS Survey Systems

    This system allows us to utilize cell phone and Bluetooth technology for communication and a network (eGPS) covering the Southeast United States for positioning. The reference stations replace the base and the cell phone technology allows the system to jump from station to station which means we can continue surveying without any distance limitations. This system achieves sub-centimeter accuracies. In addition, the equipment is less cumbersome – lightweight with no cabling. We also have the use of GLONASS and SBAS satellites in addition to the US satellites which limits downtime from lack of satellite reception. For our client, this means that we can provide greater efficiency without losing accuracy. Land & Sea Surveying utilizes the Ashtech/Magellan RTK GPS system for land-based surveying and in conjunction with our hydrographic survey system.
