How do I choose the right receiver or module?

Start with the working scenario, accuracy requirement, communication method and installation conditions, and we will suggest a model and a configuration list. The three product lines serve different purposes: choose the handheld receiver when you need a complete device, the customizable RTK module PCBA when you integrate positioning into your own terminal, and the high-precision antenna system when you need reliable satellite signal reception. See the selection guide for a side-by-side comparison.

Which accuracy figures are published?

The published figures are: the handheld receiver supports multi-constellation, multi-frequency joint solving with RTK fixed solutions, and the high-precision antenna system has a phase center error of <±2mm. The positioning accuracy of the customizable RTK module PCBA, as well as the communication interfaces, battery life, dimensions and weight of the handheld receiver, are not published as fixed numbers and depend on the project configuration - please confirm with sales.

Do you support ODM / OEM customization?

Yes. Customizable dimensions include frequency bands, interfaces, form factor, firmware and certification requirements; the exact scope and minimum order quantity are assessed per project.

Which parts of the customizable RTK module PCBA can be customized?

The module is organized in five layers, each of which can be reviewed, prototyped and validated separately: L1 GNSS antenna and RF front end, L2 RTK positioning module, L3 PCBA and interfaces, L4 embedded firmware, L5 structure and certification.

Can you provide samples for testing?

Sample testing can be arranged according to the project; please confirm the method and quantity with the technical support team at support@yueetek.com .

Choosing a Handheld RTK: The Eight Differences Between H13 and H11, and the Upgrade Path

Name: Customizable RTK Module PCBA
Brand: YUEETEK
SKU: MG20
Availability: MadeToOrder

Choosing a handheld RTK is not about which specification is larger; fix three things first, the accuracy the job needs, how the device is mounted and carried, and how data is returned and maintained.

Fix three things first, then look at the parameters

One, accuracy requirement. Work that needs a centimetre-level RTK fixed solution and fast convergence in a complex environment belongs to the H13 target scenario; work that only needs sub-metre to metre level and is mainly about position reporting and track recording is already covered by the H11 multi-frequency positioning. Writing down how much accuracy is needed and how long convergence may take is more useful than saying only that it must be accurate.

Two, mounting and carrying. Handheld survey, pole measurement, harness mounting and helmet mounting are all sensitive to weight and size: the H11 weighs 104g and suits long periods of wear; the H13 weighs 140.5g and trades this for a larger 4000mAh battery and an ISP high-definition screen, suiting all-day field work and roles that need to read values on site.

Three, communication and maintenance. If the project requires 4G full-network, remote parameter configuration, remote OTA and voice broadcast, choose the H13; if the positioning result is only returned over MQTT or HTTP, the H11 four-system multi-frequency plus NTRIP is enough to deliver. Both models share the same set of maintenance tools and data protocols (NMEA0183 / JSON / MQTT / JT/T808), so the maintenance side does not need two systems.

The parameters above are compiled from the YUEETEK website product pages and product specifications, checked on 2026-10-10. For an actual project, the specification of the corresponding batch, the delivered configuration and the technical agreement take precedence.

Scenario matching: when to choose the H13, and when the H11 is enough

Engineering survey, land resources investigation, power and water inspection, pipe networks and transport/rail, GIS collection: needs a centimetre-level fixed solution and short convergence, choose the H13.
Personnel and vehicle positioning management, field survey, inspection, security: mainly position reporting, track recording and status monitoring, the H11 is lighter and lower cost.
Single-person work needing on-site readings and voice prompts: the H13 ISP high-definition screen + voice broadcast reduce how often the phone has to be taken out to check parameters.
Long wear and weight-sensitive roles: the H11 weighs 104g, a smaller wearing burden.
Fleets or device pools needing remote maintenance and remote OTA: the H13 supports 4G remote parameter configuration, remote status query and Bluetooth 5.1 wireless maintenance.

Upgrading smoothly from the H11 to the H13

Both models share the same set of maintenance tools and data protocols (NMEA0183 / JSON / MQTT / JT/T808), so the platform side, return link and data fields of existing H11 projects can largely be reused; the upgrade cost is mainly terminal replacement and on-site configuration. Before upgrading, do two things: first, compile the accuracy requirements, communication protocols and return rate of the existing H11 project into a checklist; second, re-test the H13 time to first fix and repeatability at the same test points, and only replace in volume once the benefit is confirmed. For domestic projects, the H13 domestic version has a built-in eSIM + external Nano-SIM, which reduces on-site SIM-swap maintenance.

Frequently asked questions

Can the H13 and H11 be mixed in the same batch of projects?

Yes. Both models share the same data protocols and maintenance tools, and the platform side can parse them with the same set of fields; assign models by job accuracy requirement, rather than over-specifying in order to unify the part number.

If only position reporting is needed, is the H13 necessary?

Not necessarily. If the job only needs tracks and position reporting and does not need a centimetre-level fixed solution, the H11 four-system multi-frequency plus MQTT / HTTP return is already sufficient, at lower cost and weight.

Which parameters should be taken as authoritative?

Take the model specification of the corresponding batch and the configuration confirmed commercially as authoritative. The parameters in this article are compiled from the YUEETEK website product pages, checked on 2026-10-10, and can be used for side-by-side comparison at the selection stage.
