Home / Product Selection Guide
Selection GuideChoose between a ready-to-use handheld GNSS RTK receiver, an embedded RTK module PCBA and a high-precision antenna by starting with the working scenario, correction method and required accuracy. Follow the sequence of application, product category and key requirements to identify the configuration that should be confirmed with our sales team. This guide is based on product and solution information already published on this website. Any value not published here must be confirmed commercially.
GNSS describes the satellite systems; RTK describes how correction data improves a GNSS position.
| Term | What it means | What to confirm before selection |
|---|---|---|
| GNSS | The satellite navigation category, including GPS, GLONASS, BeiDou and Galileo. | Which constellations and frequency bands the receiver, module or antenna must support. |
| RTK | A real-time correction technique that can produce a centimetre-level fixed solution. | Correction source, communication link, convergence conditions and the accuracy acceptance method. |
Define the direction, choose the category, then lock down the requirements.
Start with the operating method and field environment: mobile data collection, integration into another terminal, or long-term fixed operation. The application determines the product direction and the interface, durability and environmental requirements that follow.
Choose a handheld GNSS RTK receiver for direct field use, a customizable RTK module PCBA for integration into your own terminal, or a high-precision antenna system for stable satellite-signal reception.
Confirm frequency bands, positioning accuracy definition, interfaces, power supply, form factor, certifications and minimum order quantity. Values not published on the website must be confirmed commercially and should not be inferred.
The table summarizes typical applications, key requirements and delivery models by category.
| Product line | Typical applications | Key requirements | Delivery model |
|---|---|---|---|
| Handheld GNSS RTK Receiver | Surveying and GIS, engineering inspection, mobile data collection, professional field operations | Multi-constellation and multi-frequency positioning, RTK fixed solution, field data collection and real-time transmission, IP67 protection. Confirm communication interfaces, battery life, dimensions and weight with our sales team. | Complete device |
| Customizable RTK Module PCBA | Industrial positioning terminals, automation and robotics, survey and inspection equipment, industrial IoT | Customization scope covering frequency bands, interfaces, form factor, firmware, certification and minimum order quantity; integration capability across multiple bands, interfaces and protocols. Confirm positioning accuracy, power supply and consumption, dimensions and interface definitions with our sales team. | Prototype validation / pilot production / volume delivery |
| High-Precision Antenna Systems | High-precision positioning terminals, reference stations and base stations, unmanned systems, industrial integration equipment | Frequency range, peak gain >= 5.5 dBi, phase-center error < +/-2 mm, RHCP polarization, 50 ohm impedance, LNA gain 40 +/-2 dB, mechanical dimensions and IP67 protection. | Project-specific adaptation and reliability validation |
Use the operating scenario to identify the usual product combination.
| Application | Typical product combination | Notes |
|---|---|---|
| Surveying and GIS | Handheld GNSS RTK Receiver + High-Precision Antenna Systems | Supports field work in complex terrain and point collection. Integrated RTK collection reduces station changes and stores point records consistently. |
| Precision agriculture | Customizable RTK Module PCBA | Provides stable heading and route records for seeding and fertilizing, reducing overlaps and missed areas. |
| Digital construction | Positioning terminal and antenna | Machine guidance and stakeout can directly use coordinate data for roads, pipelines and municipal projects. |
| Smart manufacturing | Positioning module and data platform | Supports online management of vehicles and material status in industrial parks. |
| Smart fuel stations | Smart Fuel-Station Supervision Solution | Collects terminal and monitoring-unit data for centralized monitoring and auditing across multiple stations. |

The questions asked most often during selection.
Choose the handheld GNSS RTK receiver when you need a complete device for field collection and real-time upload; choose the customizable RTK module PCBA when positioning has to be integrated into your own terminal or equipment. The comparison table above lists typical applications, key requirements and delivery methods for both.

A GNSS receiver calculates position from satellite signals. RTK adds real-time corrections from a base station or network service; with stable corrections and geometry, the receiver resolves carrier-phase ambiguities and reports a fixed solution. Confirm the correction source and communications link as part of product selection.
