ArduSimple Alternative: Why an Integrated RTK Receiver Now Fits Every Stage
On this page
TL;DR
Keep simpleRTK boards when you need receiver configuration, antenna experiments, or custom hardware. Consider an integrated RTK receiver when you want a supplied antenna, enclosure, and host connection for field use. You can start with either format: learning the hardware favors a board; testing an application with position data may favor a packaged receiver. ArduSimple sells both, so compare complete configurations.
A simpleRTK setup can produce an RTK fix on the bench and still need work before anyone can install it outdoors. The antenna needs a suitable location, cables need securing, and the next operator needs to know how to start the receiver and recognize a lost correction stream.
This ArduSimple alternative guide looks at those installation decisions. It compares the simpleRTK board path with packaged receivers, including ArduSimple's own professional kits and handheld products. For a broader choice between modules, boards, and finished receivers, start with the GNSS Receiver Guide.
What simpleRTK Boards Are Good At
simpleRTK boards let you work directly with the receiver, its connectors, and its configuration. The simpleRTK2B Budget user guide walks through connecting an antenna and PC, inspecting output in u-center, and supplying corrections for RTK operation.
In this workflow, NTRIP delivers corrections from an internet caster or service. RTCM is the correction-message format sent to the receiver. Boards based on the u-blox ZED-F9P give engineers a way to test that chain before designing their own hardware.
You can change antennas, inspect receiver settings, try compatible radio or Bluetooth accessories, and connect to a host or autopilot through the board's documented interfaces. That access is useful when the final product will use a custom carrier, wiring harness, or enclosure.
Where ArduSimple Still Fits
The question is what you need to learn or change. A newcomer who wants to understand receiver configuration benefits from board access. A newcomer who wants coordinates for a mapping app may have little reason to assemble the hardware first.
- Receiver evaluation. You need to inspect u-blox settings, output messages, correction input, or antenna behavior.
- Custom embedded design. Your team will design the carrier, power supply, antenna installation, and enclosure.
- Autopilot and robotics experiments. You need accessible connectors and the ability to change wiring during bring-up.
- Hardware teaching. Students need to see how the antenna, receiver, corrections, and host fit together.
Plan for the Installation
Board access lets you make more of the hardware decisions. Include the enclosure, connectors, antenna mount, power supply, and installation instructions in that design work, even if the first test only needs a USB cable.
When Board-Level Integration Starts to Cost Time
The extra work often appears when a working prototype moves onto a machine or into an operator's hands:
- Antenna placement. Sky view, nearby metal, ground-plane requirements, and the antenna cable can affect reception.
- Weather protection. An antenna's IP rating does not protect an exposed board. Check the housing, connector seals, and cable exits separately.
- Mounting and vibration. Secure the receiver and cables so normal handling or machine movement does not pull on connectors.
- Power and interference. Test with the actual host, motors, and radios running, rather than only on a quiet USB bench.
- Operator handoff. Write down startup, correction checks, and recovery steps that someone else can follow.
Compare the cost of the completed installation. A board price excludes some combination of antenna, enclosure, cable, mount, assembly, and testing. A packaged receiver includes more of that hardware, but its price alone does not tell you whether it meets the job. Total cost of ownership also includes replacements, configuration records, and the time needed to diagnose a field failure.
With several units, record firmware, settings, and wiring consistently. A supplied enclosure and cable can reduce assembly variation; they do not prevent configuration drift or remove the need to test the host application.
| Layer | simpleRTK board path | Integrated receiver path |
|---|---|---|
| Receiver access | Direct access to the board's documented connectors and receiver configuration. | Access through the finished product's supported interfaces and settings. |
| Antenna | Select and install an external antenna; some kits supply one. | May include an integrated or supplied external antenna. Check the specific model. |
| Field hardware | Choose the housing, cable protection, mount, and weather sealing. | Check the supplied housing and cable; design the mount and routing for the site. |
| Host integration | Select wiring and settings, then validate the host connection. | Validate the supplied interface, messages, timing, and correction input. |
| Position and raw data | Depends on the receiver and firmware; F9P workflows can expose NMEA, UBX, and raw observations. | Depends on the product. NMEA position output does not establish raw-observation support. |
| Multiple units | Repeat and document assembly, settings, and testing. | Repeat the mounting and software setup; retain configuration and test records. |
| System cost | Add accessories, assembly, validation, and support to the board price. | Check what is included, then add the remaining installation and support work. |
ArduSimple Alternative: Integrated RTK Receiver Tradeoffs
A packaged receiver is useful when its supplied hardware matches your installation. You still choose the mounting location, correction source, and host software. You also accept the interfaces and configuration options the product exposes.
For example, the documented SCOUT Series USB serial connection to AgIO provides GNSS data without a custom interface board. Steering and vehicle-control hardware remain separate responsibilities.
The same receiver can serve evaluation, field trials, and a small batch if its interface, output rate, and mounting suit all three. That is the sense in which an integrated receiver can fit every stage. Changing requirements may still call for a different receiver or a custom board.
| Option | Useful for | Work still required | Typical fit | Reconsider when |
|---|---|---|---|---|
| simpleRTK board | Receiver access, antenna experiments, and custom wiring. | Housing, wiring, mounting, power, and field validation. | Hardware learning, research, and embedded prototypes. | You need supplied field packaging and have no plan to build it. |
| Integrated RTK receiver | A supplied housing, antenna arrangement, and host interface. | Host software, corrections, installation, and validation. | Field collection, robots, and machines with a compatible host. | You need connectors, raw data, or hardware changes it cannot provide. |
| Survey handheld or rover | Pole use, operator tools, and supported survey workflows. | Check app, controller, corrections, and measurement requirements. | Human-operated mapping, layout, and control-point work. | The selected system does not suit your host, fixed mount, or required workflow. |
Comparing a simpleRTK2B Kit with a Packaged Receiver
If you are looking for a simpleRTK2B alternative, compare the kit you would actually buy. The Basic Starter Kit, AS-STARTKIT-BASIC-L1L2-NH-03 already includes an antenna. ArduSimple also sells a packaged F9P receiver, the RTK Smart Antenna.
| Check | simpleRTK2B Basic Starter Kit | ArduSimple RTK Smart Antenna | SCOUT Standard RTK |
|---|---|---|---|
| Included hardware | L1/L2 F9P board and external ANN-MB antenna with 5 m cable; no board enclosure or USB cable. | L1/L2 F9P receiver, antenna, and battery in an IP65 housing. | L1/L5 receiver and antenna in an IP67 housing, with a 3 m USB cable. |
| Connection | USB-C on the NH-03 board; other documented board interfaces. | USB-C and Bluetooth/BLE. | USB-C for NMEA output and host-fed RTCM corrections. |
| Main decision | Do you need F9P configuration and board-level access? | Do you need a battery-powered F9P receiver with wireless access? | Does a wired host workflow with 1 Hz position output meet the task? |
The kit's antenna rating does not weatherproof the board. SCOUT Standard RTK is specified at ≤10 cm CEP with RTK Fixed; check that tolerance against your requirement and validate the field installation. The kit can be configured up to 10 Hz. If you need more than 1 Hz, SCOUT Standard RTK is not a direct replacement. The SCOUT RTK+DR configuration outputs at 10 Hz and should be assessed separately.
SCOUT is compared here on its documented USB path for NMEA output and host-fed RTCM input. If your workflow depends on F9P-specific configuration, UBX, raw observations, PPK, or an established base setup, do not treat SCOUT as a verified replacement. Keep the kit or choose a receiver documented for that workflow.
Field Example: Static Point Collection
Suppose you are collecting soil-sampling locations or mapping points around a trial plot. You already have a host and collection app; you need the receiver to accept corrections and report positions at the required rate. This is a workflow example, rather than a field-accuracy test.
- Connect the receiver and corrections. The host's NTRIP client retrieves RTCM data and forwards it to the receiver.
- Check the solution before recording. Read the NMEA fix state and verify that corrections continue arriving. An RTK Fixed indication alone does not prove the point meets your accuracy tolerance.
- Follow the measurement procedure. Keep the antenna in the intended position, use the correct coordinate settings and antenna-height treatment, and apply the app's required averaging or quality checks.
- Test recovery. Confirm what the app shows and records if corrections stop or the receiver reconnects.
For an open-sky task that accepts 1 Hz output and the published accuracy specification, SCOUT is a receiver to evaluate with that host and app. An integrated antenna still needs a suitable mounting location and sky view. A receiver does not supply the correction subscription, host, or measurement workflow.
SCOUT PRO is a separate product family: its Standard RTK configuration outputs at 1 Hz, and its RTK+DR configuration adds a 6-axis IMU and 10 Hz output. Dead reckoning is relevant to moving platforms during short GNSS interruptions; it is not a reason to select the DR version for static point accuracy.
For the PRO hardware background, see Why Kalmix Chose AG3335 and the variant differences. Teams designing their own AG3335-based hardware can instead evaluate the Kalmix GUIDE module family; module integration requires its own electrical and software design.
If the host is a phone, use the phone-based RTK guide to check the connection and app requirements. The SparkFun RTK Alternative covers another board-to-field comparison.
For a ROS node, ArduPilot setup, PX4 integration, or custom host, check what that particular configuration expects. If it already reads NMEA and forwards RTCM, test messages, baud rate, update rate, timestamps, and fix-state handling on the replacement receiver. A USB connection alone does not establish compatibility. For localization, sensor fusion, and correction-loss handling, continue with RTK GPS for Robotics.
Migration Path
Start with one replacement unit. Keep the host, correction provider, coordinate settings, and test locations consistent where possible. This compares complete installations; changing the receiver and antenna does not isolate the effect of packaging.
- Record the current setup. Note antenna, mount, cable routing, firmware, corrections, messages, rate, and acceptance criteria.
- Run the required task. Check startup, position output, correction reception, and the app's stored results.
- Repeat the installation checks. Test cable handling, correction loss, reconnection, and startup across several sessions.
- Have another operator repeat it. Fix missing instructions before ordering or installing more units.
Who Should Not Switch
Keep the board if your project depends on F9P-specific configuration, receiver test access, interchangeable antennas, radio accessories, or a custom carrier. Those are reasons to retain hardware control, even for a deployed product.
Also keep a proven raw-observation or post-processing setup until the replacement has documented support and passes your workflow test. For a packaged F9P kit, compare its actual interfaces and accessories with the proposed replacement; the board-versus-enclosure argument may no longer apply.
Conclusion
The choice depends on what your team needs to build. simpleRTK boards suit projects that need receiver access and custom hardware. An integrated RTK receiver can suit application testing from the start, then field use, when its output, interfaces, and installation meet the requirements. Compare the specific products and test one complete setup before scaling.
Key Takeaway
Write down the required messages, rate, accuracy, correction path, and mounting conditions first. Then decide whether your team needs to design the hardware around the receiver or can use a supplied unit.
Frequently Asked Questions
What is an ArduSimple alternative?
Here, it means a receiver compared with the simpleRTK board path for the same task. ArduSimple also sells packaged receivers, so compare the specific kit, interfaces, included hardware, and supported workflow. A packaged unit may suit application testing as well as field use.
When should I use simpleRTK boards?
Use them when you need receiver configuration, antenna experiments, accessible connectors, or custom hardware. They also suit teaching the hardware and correction chain. If you only need position data for an application, evaluate a packaged receiver with the required interface and output.
When do I need an integrated RTK receiver?
Consider one when its supplied antenna, enclosure, and connection cover the hardware you would otherwise assemble. It can be useful from the first application test. You still need compatible host software, corrections, suitable mounting, and a validation procedure.
Is an integrated RTK receiver more expensive than a simpleRTK board?
It depends on the selected products and what their prices include. Compare completed installations: receiver, antenna, enclosure, cables, mounting, assembly, testing, and support. A bare-board price and a packaged-receiver price cover different amounts of that work.
Can I keep my NTRIP service and host software when moving from a board?
Often, if the replacement accepts the service's RTCM messages and the host supports its output and connection. Check the message set, baud rate, update rate, timestamps, fix-state handling, and reconnection behavior. An existing USB or NMEA path still needs testing with the selected receiver.
What output does SCOUT PRO provide, and does it support raw observations?
SCOUT PRO provides NMEA 0183 over USB-C: 1 Hz for Standard RTK and 10 Hz for RTK+DR. NMEA positions are not raw observations. For PPK or another raw-data workflow, obtain configuration-specific documentation and verify the recording and processing chain before treating it as a replacement.
For static field or survey point collection, do I need the dead-reckoning version?
Usually no. Dead reckoning addresses short GNSS interruptions on moving platforms; it is not a static-accuracy upgrade. Evaluate Standard RTK against the required accuracy and output rate. A Fixed indication alone does not establish measurement accuracy, and the app, antenna placement, corrections, and recording procedure still matter.
Can SCOUT replace a simpleRTK2B kit?
SCOUT Standard RTK is a candidate for host-based, real-time collection that accepts 1 Hz NMEA output and its published ≤10 cm CEP specification with RTK Fixed. It includes the antenna, housing, and a 3 m USB cable. If you need F9P-specific configuration, UBX, raw observations, PPK, or an established base setup, do not treat SCOUT as a verified replacement; keep the kit or choose a receiver documented for that workflow.
