GNSS Receiver Manufacturers in China: Brands, Suppliers and Sourcing Tips

China has become an important source of GNSS RTK receivers for land surveying, construction and geospatial projects. Buyers searching for GNSS receiver manufacturers in China will find established equipment brands, specialized GNSS technology developers and companies supplying instruments for international markets.

However, identifying a Chinese GNSS brand is only the first step. Before placing an order, buyers need to understand who develops the equipment, who supplies it, and which technical requirements must be confirmed.

This guide introduces several Chinese GNSS receiver brands and explains how international buyers can make practical sourcing decisions.

Major GNSS Receiver Manufacturers and Brands in China

Several Chinese companies develop GNSS positioning equipment for professional surveying. Their product portfolios and target applications differ.

Hi-Target — Surveying and Geospatial Equipment

Hi-Target is a Chinese surveying equipment company with a broad range of geospatial products, including GNSS RTK systems, total stations, laser scanning equipment and hydrographic solutions.

Its GNSS range includes conventional RTK receivers alongside visual and laser-assisted models.

For example, the Hi-Target V200 is a conventional surveying receiver, while the V600L is designed for applications that benefit from laser-assisted, non-contact measurement.

Buyers should compare these models according to the field workflow rather than assuming that additional features are necessary for every project.

CHCNAV — GNSS Positioning and Integrated Surveying Solutions

CHC Navigation, commonly known as CHCNAV, is a Shanghai-based positioning and mapping technology company.

Its products cover GNSS surveying, positioning systems and other geospatial applications.

CHCNAV offers different receiver configurations for surveyors who need portable equipment, tilt measurement and integrated field workflows.

When evaluating CHCNAV equipment, buyers should consider the receiver, field controller and software as a complete working system.

ComNav Technology — GNSS Receivers and OEM Technology

ComNav Technology is another Chinese GNSS technology company. Its business includes GNSS receivers, OEM boards and positioning solutions.

This distinction matters because the term GNSS manufacturer can refer to different activities.

Some companies develop GNSS boards or positioning technology used inside other equipment, while others sell complete surveying systems with field software and accessories.

For a surveying contractor, purchasing a complete RTK system is different from sourcing GNSS components for integration into another product.

SOUTH, KOLIDA and FOIF — Additional Chinese Surveying Brands

SOUTH, KOLIDA and FOIF are also familiar names in the Chinese surveying equipment market.

Their available product ranges include GNSS RTK receivers and other surveying instruments, depending on the brand.

For international buyers, the practical comparison should be made at the model level. Two receivers may both advertise multi-constellation positioning and centimeter-level RTK performance while differing in radio compatibility, field software, tilt functions and package contents.

GNSS Manufacturer vs Supplier: What Is the Difference?

A GNSS receiver manufacturer develops or produces positioning equipment. Depending on the company, its activities may include hardware design, GNSS technology development, receiver assembly, software and product testing.

A GNSS receiver supplier provides equipment to customers. A supplier may specialize in one brand or offer products from multiple brands.

For buyers, the distinction affects the purchasing process.

A supplier is not automatically a manufacturer, and a manufacturer does not necessarily sell every product directly to international buyers.

RTKSurvey.com is a China-based surveying equipment supplier, not a GNSS receiver manufacturer. We provide access to multiple surveying equipment brands and help international customers compare models and purchasing requirements.

Practical Case: A Distributor Needs Two Types of RTK Equipment

Illustrative sourcing scenario — not a documented customer transaction.

A surveying equipment distributor is preparing to expand its product range.

Its customers fall into two groups:

• Small land-surveying teams that need straightforward RTK equipment for everyday topographic surveys.

• Construction contractors that want IMU tilt compensation and more efficient stakeout workflows.

The distributor initially considers ordering 15 identical receivers from one Chinese manufacturer to simplify purchasing.

However, the two customer groups have different requirements.

A more useful evaluation might involve testing a conventional RTK model alongside an IMU-equipped receiver before deciding on quantities.

During the evaluation, the distributor discovers that the most important questions are not limited to the GNSS specifications:

First, correction compatibility. Both receiver configurations must work with the NTRIP services commonly used in the target market.

Second, field software. Customers need coordinate system settings, stakeout functions and data export formats suitable for their projects.

Third, training and support. The distributor must understand the configuration process well enough to help customers begin using the equipment.

Fourth, total package cost. A receiver-only quotation cannot be compared directly with a package that includes a controller, software and accessories.

The distributor can then choose a product mix based on actual customer needs instead of purchasing one configuration for every application.

Sourcing lesson: A Chinese GNSS receiver manufacturer may offer several technically different models. Choosing the right combination is more important than buying a large quantity of a single receiver.

Is GNSS Equipment Made in China Suitable for Professional Surveying?

The country of origin alone does not determine GNSS surveying performance.

A professional receiver should be evaluated through its published specifications, supported correction formats, field software and performance under relevant operating conditions.

For example, a receiver may obtain an RTK Fixed solution in an open field but perform less consistently near buildings, trees or reflective surfaces.

Buyers should also verify measurements against known control points. A Fixed solution does not guarantee that the selected coordinate reference system or localization parameters are correct.

The same principles apply to GNSS receivers manufactured in China and elsewhere.

Five Questions to Ask Before Sourcing GNSS Receivers from China

1. Is the exact receiver model available?

Confirm the full model name, configuration and included components. Similar model names do not always mean identical capabilities.

2. Does it support the correction service used in your country?

Ask about NTRIP, RTCM support, local CORS compatibility and UHF radio options where relevant.

3. Which software and controller are included?

Clarify software licensing, controller compatibility, coordinate transformation features and data export requirements.

4. What does the quotation include?

Confirm whether the price covers the receiver alone or a complete surveying package, including poles, controllers, cases and other accessories.

5. How will after-sales issues be handled?

Discuss warranty terms, technical documentation, software support and the process for resolving equipment problems before ordering.

These questions help buyers compare quotations on a consistent basis, regardless of whether they purchase directly from a manufacturer or through a supplier.
