CHC vs Leica, Trimble, GeoMate, EOS, Sokkia

When comparing CHC DGPS to other industry-leading brands like Leica, EOS, Trimble, Kryptton, and GeoMate, CHC stands out as a well-balanced solution offering professional-grade accuracy at a significantly more competitive price point.

CHC DGPS vs Leica DGPS

Leica is known for its premium build and unmatched precision, but it comes at a premium cost. CHC DGPS offers comparable centimeter-level RTK accuracy and full GNSS support, making it a practical alternative for budget-conscious surveyors without compromising on core performance.

CHC DGPS vs Trimble DGPS

Trimble systems excel in automation and integration but often require expensive subscriptions and software. In contrast, CHC DGPS delivers reliable positioning with simplified setup and compatibility with multiple survey software platforms making it easier to adopt in mixed-fleet environments.

CHC DGPS vs EOS GNSS

EOS GNSS receivers are typically used for GIS and mobile mapping. While EOS emphasizes app-based workflows, CHC DGPS is better suited for traditional surveying, offering stronger field ruggedness, tilt compensation, and versatile connectivity options including UHF, 4G, and Bluetooth.

CHC DGPS vs Kryptton DGPS

Kryptton offers economic GNSS solutions, but CHC wins in terms of real-time accuracy, satellite tracking capability, and long-term software support. CHC DGPS devices also feature IMU-based tilt correction and higher data refresh rates, ideal for fast-paced projects.

CHC DGPS vs GeoMate DGPS

GeoMate DGPS is widely used across India for government and infrastructure work. While both offer robust solutions, CHC DGPS often provides broader global support, better firmware upgrades, and extended RTK coverage making it a future-ready choice for scaling operations.

CHC i73 vs i50

If you’re considering a CHC DGPS for your survey projects, two standout models often come up: the CHC i73 and CHC i50. Both offer centimeter-level GNSS accuracy, robust field performance, and modern connectivity, but they cater to slightly different needs.

The CHC i73 is a compact, next-generation GNSS receiver built for high-mobility and advanced applications, featuring IMU-based tilt compensation and a lightweight design. The CHC i50, on the other hand, is a more traditional base-rover system, ideal for users who prefer a classic form factor with powerful RTK performance.

Choose the CHC i73 if you need a lightweight, tilt-enabled rover for dynamic survey conditions and fast deployment.

Opt for the CHC i50 if you prefer a budget-friendly GNSS system for base-rover setups and standard RTK workflows.

CHC DGPS vs RTK

CHC DGPS uses differential corrections from a base station to improve GNSS accuracy. It typically delivers sub-meter to decimeter-level accuracy, which is ideal for applications like GIS mapping, basic construction layouts, and agricultural planning. CHC DGPS receivers are cost-effective and reliable for standard survey needs.

RTK (Real-Time Kinematic) is a more advanced GNSS technique available in CHC systems like the i73 and i90. It delivers centimeter-level accuracy in real time by receiving corrections over UHF or 4G from a base station or CORS network. RTK is essential for high-precision tasks such as land subdivision, road alignment, pipeline layout, and control surveys.

Choose CHC DGPS for reliable positioning where sub-meter accuracy is sufficient.

Go with CHC RTK when you need precise, real-time results for engineering and cadastral survey work.

How To Use CHC DGPS

Using a CHC DGPS is simple, even for beginners, thanks to its user-friendly interface, advanced features, and compatibility with survey software like CHC LandStar, SurvCE, and FieldGenius. Whether you’re conducting topographic surveys, boundary marking, or construction layout, CHC GNSS receivers make fieldwork fast and accurate.

Step-by-Step Guide to Using CHC DGPS

1. Power On the Receiver
Start by turning on your CHC DGPS device (e.g., i73 or i50). The LED lights will indicate system status and satellite lock.

2. Connect to Your Controller or Mobile Device
Pair your CHC DGPS with a data controller or Android tablet via Bluetooth, Wi-Fi, or 4G. You can also use CHC’s LandStar7 app for easy configuration.

3. Configure GNSS Settings
Choose your satellite constellations (GPS, GLONASS, Galileo, BeiDou) and enable RTK mode or DGPS corrections, depending on your application.

4. Set Up Base and Rover (for RTK)
For RTK surveys, set up one receiver as a base station and the other as a rover. Use UHF or 4G to transmit corrections.

5. Start Surveying
Begin collecting points, stakeout tasks, or mapping boundaries. CHC DGPS systems support IMU tilt compensation, so you can measure without leveling the pole saving time and improving efficiency.

6. Save and Export Data
Once done, save your survey data in formats like CSV, DXF, SHP, or RINEX. Export directly to your GIS or CAD workflow.

Tips for Best Results With CHC DGPS

• Calibrate the IMU sensor before starting.
• Use a CORS network if no base station is available.
• Regularly check firmware updates from CHCNAV for optimal performance.

CHC DGPS receivers are designed to simplify field operations without compromising precision. With just a few steps, surveyors can achieve high-accuracy positioning across India’s toughest terrains.

CHC DGPS Frequently Asked Questions

1. What is the accuracy of CHC DGPS in real-world survey conditions?

CHC DGPS receivers offer centimeter-level accuracy when used with RTK corrections and proper satellite coverage. In RTK mode, most models like the CHC i73 or i50 deliver ±8 mm horizontal and ±15 mm vertical accuracy. In standard DGPS mode without RTK, accuracy typically ranges from 30 cm to 1 meter. The actual results may vary slightly depending on terrain, signal quality, and satellite availability. CHC devices also support multi-constellation GNSS (GPS, GLONASS, Galileo, BeiDou), which improves reliability in urban or semi-blocked environments. Many Indian surveyors have reported highly stable accuracy using CHC DGPS even in remote locations.

2. Is CHC DGPS compatible with Indian CORS networks?

Yes, CHC DGPS systems are fully compatible with Indian CORS (Continuously Operating Reference Station) networks. Models like the i73, i50, and i90 support NTRIP connections via 4G SIM or Wi-Fi, allowing real-time RTK corrections through state-run or private CORS services. This eliminates the need to carry a physical base station for every job. Compatibility with CORS networks ensures faster setup, reduced equipment costs, and reliable positioning even in challenging terrains. Surveyors across states like Maharashtra, Tamil Nadu, and Karnataka have successfully used CHC DGPS with local CORS systems.
