We provide a wide variety of corrections:

 

RTK Correction (Get Pricing)

  • Within the limits of our Network Coverage, eGPS provides raw Real Time Kinematic (RTK) GNSS corrections with a precision of 1 cm +/- horizontally and 2 cm +/- vertically.
  • Distance dependent errors are considerably minimized with utilization of the eGPS RTN, thereby achieving increased accuracy, precision, and reliability.
  • RTK Surveying works at its optimum with a RTN to achieve the pinnacle of RTK Technology production potential.

Possible Fields of Application

Staking

  • Engineering Survey
  • Topographic Survey
  • Boundary Survey
  • Construction Staking
  • Utility Extension Survey
  • Flood Survey Study and Analysis
  • Photogrammetric Control Surveys
  • GIS Applications
  • Hydrographic Survey
  • Precision Agriculture
  • Machine Control

Hardware Requirements

The eGPS Solutions corrections can be applied to any mobile GNSS receiver capable of connecting to a cellular modem using Bluetooth or wired technology. The benefits of a true, wireless operation should not be ignored; however, older technology requiring cable connections to the cell phone and data collector also successfully use eGPS Solutions RTN. The highly qualified eGPS Solutions staff can assist with any hardware evaluations.

DGPS Correction (Mapping Grade) (Get Pricing)

  • This application is a sub-meter Mapping and Navigation Technology.
  • The service provided by eGPS Solutions includes data for post processed positioning and Real Time Correction. Any receiver that is capable of Real Time Corrections and cellular modem service can be used to receive eGPS Solutions & Real Time RTCM corrections.
  • Distance dependant errors are eliminated for users due to the dense array of reference stations operated by eGPS Solutions.
  • Mapping grade subscribers may also post process through RINEX downloads.

Possible Fields of Application

Retention
  • Wetland Location Surveys
  • Soil Location Survey
  • Clearing Limits
  • Tree Surveys
  • GIS Inventory Surveys
  • Mapping and Navigation
  • Other Sub-Meter Uses

Hardware Requirements

The eGPS Solutions correction can be applied to any mobile receiver capable of connecting to a cellular modem. Cell phone reception, therefore, is a requirement of the DGPS (RTCM) correction service. Mobile receivers are available enabling the use of a wireless connection to the cellular modem and data collector.

Precision Ag (Get Pricing)

  • Within the coverage area, eGPS Solutions provides corrections for precision guidance. Precision guidance to the sub-inch year-to-year accuracy is reliable throughout Georgia and Florida.
  • Savings occur through fuel savings, fertilizer savings, and time savings.
  • Ultra-precise elevation mapping
  • Through cellular modems, corrections are more reliable and robust than through UHF radio transmissions.
  • Sometimes farmers don't need a full network. When their crop is within a 20-mile radius we can provide single base corrections.
  • Virtual Reference Stations allow farmers with multiple fields to use GNSS with a continuous connection and calibration. So farmers get the flexibility of that reliability.
Precision AG

 Possible Fields of Application

  • Field Guidance
  • Row Crop Driving
  • Elevation Mapping (DTM)
  • Precise corrections
  • Other Sub-Meter Uses (DGPS)

Hardware Requirements

The eGPS Solutions corrections can be received by using a GNSS/GPS receiver on top of the cab of a tractor capable of CMR or RTCM corrections. The systems require a small computer placed in the cab, and a modem or cell phone with a data plan.

"Metro Engineering & Surveying Co. uses EGPS daily. Our 2 subscriptions have increased our efficiency in providing service to our clients state wide. We have expanded from our original applications for Photo Control and GIS Project Control to include Field Topos and Site Construction Staking.

With our recent purchase of the Harrier 56/G3 LiDAR and Digital Imagery System and installation in our aircraft and helicopter, we use data from EGPS Base Stations, merged with GPS Data collected during our flights, to process the exact position of our instruments at each event. We have also used these Base Stations as control during airborne GPS Photo Capture.

The EGPS Base Stations have reduced our Field GPS Base Station observations by 75%. We appreciate the good service."

- James E. Sease, President
Metro Engineering & Surveying Co., Inc., Hampton, GA


"Prime Engineering was using a Trimble R8 equipped with eGPS. Our crew chief fell in the creek and he and the equipment were immersed. The GPS equipment was fine but the cell phone died a watery death. We contacted Jeff Little of eGPS to get phone recommendations. Within an hour of the phone failing, Jeff met our party chief at the Verizon store to help us get the right phone and get up and running again.

That is exceptional support.

We at Prime appreciate your timely assistance."

Prime Enginering, Atlanta, GA


"With the service that eGPS has provided surveyors of the State of Georgia, we can now cut out at least 1 day of field work and 1 day of reconnaissance, depending on job size. eGPS had made GPS surveying more profitable at a reasonable price.

We have easily doubled our productivity on topo jobs in appropriate areas.

Accuracy has been incredible, while using the equipment and appropriate times and in appropriate places. With a common sense GPS approach, you can easily repeat accuracies of 0.05' horizontal and 0.07' vertical, most of the time doing better than that.

The easiest part of the system is just getting up and running. eGPS and Lonnie Sears will train you and stay in touch with you not only until you are comfortable, but until they are comfortable. I've never had better, more efficient training than what eGPS and Lonnie Sears has provided me."

"We list the local monuments in our software, set up control and use eGPS to stake out the nearest monument and double-check the accuracy," he says. "We want to get the eGPS value instead of the recorded value. The accuracy is much better."

- Thomas E. Peay, Jr., RLS
Frontline Surveying & Mapping, Inc., Marietta, GA


"Woolpert currently has three 'roving' GPS units collecting cm accuracy positions in the Fulton and Gwinnett county areas. We have found their services to be affordable and highly reliable..You will find their staff knowledgeable and helpful."

- David Wilkins, PLS
Woolpert, Inc., Atlanta, GA


"A major benefit [of the system] is [in] reducing the number [of survey monuments] and [the] effort in finding survey monuments. In the past, we could spend half of a day and as much as a few days finding adequate monumentation prior to eGPS. That's quite a bit of time savings."

- Lewis Brown, RLS
Wolverton & Associates, Inc., Duluth, GA


"I had a voice mail this morning from one of our crew chiefs ( Jason Butler ) reporting that you stopped alongside I-285 Friday evening and helped him change a flat tire on his company truck. I really appreciate that Jeff and I know that it was not the safest location for working on a vehicle. As always – excellent customer care from 'eGPS'."

- Robert Bradford, RLS

"I was working late in the day on a Saturday and called with a problem. Not only did eGPS answer the call, they talked me through the problem immediately."

- Pete Nunn
Georgia Professional Land Surveying


"Having the eGPS Network Access takes away the time of setting up a base station and gives you the flexibility to cover more ground faster.

Service & Support are very good, the people at eGPS are easy to talk to and can explain situations very clearly.

We had a crew that was out in the field who was sent a "Breaking News" e-blast about stations being down in Florida, They we able to change their plans without losing any time on the job."

- Tim Gebauer
Geomatics Corp


"eGPS always responds to on-site/in the field issues promptly, they are always available."

- Colin Gowens
Fulton Count GIS Department


"eGPS has the coverage area I need, their claims of accuracies and repeatabilities are consistently great, and they are constantly communicating everything from station information to satellite availability and training opportunities.

Lonnie has always helped us through any problems we may have."
