Data Reliability

The eGPS Solutions network's mission is to operate 24 hours a day, seven days a week. The network software performs quality and data integrity checks continuously by relative positioning between base antennas. The network is monitored during regular business hours, 8:00 AM until 5:00 PM, Monday through Friday.

eGPS Solutions’ system reports WGS-84 datum. The antenna locations are surveyed in from HARN monuments and vertical control monuments throughout North Georgia. The values of these are presently being Bluebooked through NGS.

The maximum Positional Error Tolerance of points that eGPS Solutions systematically observed using a VRS correction over a period of months and with one minute of data:

eGPS Solutions recommends that users verify their own data by observing existing survey monuments near their projects as datum verification, and that they repeat observations to model positional error tolerances for themselves. This verification would be similar to use of a calibrated baseline for EDM equipment verification.

All major manufacturers’ receivers and data collectors can be used in the eGPS Solutions network. The system broadcasts CMR+, and RTCM correction formats.

Rover-receivers may function with different cell phone modems, data collectors and software than those utilized with the eGPS Solutions rover-receivers. The specialists at eGPS Solutions can advise users and offer their support to obtain the proper configuration of subscriber’s equipment through the manufacturer’s support system. Upon proper configuration of the equipment, the data reliability of eGPS Solutions’ service can be checked by subscribers at anytime by simply logging into the network.

System downtime is viewed as unacceptable. Any break in data streaming will be met head-on, and resolved quickly to restore the RTK correction signal and the RINEX storage.
