Meet GrowSpace Q1

This is Q1

A UWB RTLS platform that turns any indoor space into real-time location data. Set it up yourself, track in centimeters, and build on it with your own code — from a first PoC to a full research project. Whether you're tracking people, equipment, or autonomous robots, Q1 gives you the raw coordinates to build exactly what you need. Hardware, software, and positioning engine are all developed in-house — one system designed to work together.

Built for developers

Built to be precise. Built to build on

Precise positioning

10–30 cm accuracy at up to 10 updates per second.

Connect and code

Raspberry Pi, Arduino, PC — drive it from your own code.

Ready out of the box

Hardware and software together — nothing else to buy.

Scales with you

Add a gateway to track every tag from one place — 15 tags at 10 Hz, ~150 at 1 Hz.

FAQ

Questions developers ask first

What is included in each kit?
Creator Kit — 3 anchors, 1 listener, 1 developer tag, 3 brackets and USB Type-C cables.
Expansion Kit — 4 anchors, 1 gateway, 1 developer tag and 4 Z brackets.
How many tags can be tracked simultaneously?
It depends on the update rate. 15 tags at 10 Hz, or roughly 150 tags at 1 Hz. The gateway handles up to 150 messages per second. A common approach is to run a PoC at 10 Hz, then lower the rate as tag count grows in production.
What accuracy and range can I expect?
Average positioning accuracy is 10–30 cm both indoors and outdoors, with a maximum measurement range of 25 m in line of sight. Recommended anchor spacing is 15 m indoors and 20 m outdoors — indoor spaces need denser placement because walls, furniture and ceiling structures reflect or block the signal.
How many anchors do I need?
Distance measurement only: 1 anchor. 2D positioning (RTLS): at least 3 anchors for trilateration. 3D positioning including the Z axis: 4 or more recommended. A single PAN ID supports up to 30 anchors including the initiator.
Do I need to install an SDK?
No SDK installation or build step is required. Connect the listener or developer tag over USB-C to a PC, Raspberry Pi or Arduino, open a serial terminal such as Tera Term, and coordinates stream out directly. The lep command outputs coordinates and a quality factor as CSV; lec adds ranging data. Python example code and an Arduino library are provided.
What format does the data come in?
Listener (serial) — plain string output:
POS,0,08A8,-1.22,10.14,1.60,61
In order: data type, PAN ID, tag ID, X/Y/Z coordinates in metres, quality factor.

Gateway (MQTT) — JSON:
{"gatewayID":"GR1234","tags":[{"id":"GR8a8","panID":"0001","x":-1.25,"y":10.12,"z":1.57}]}
Can I integrate it with Python or other environments?
Yes. The system is MQTT-based, so you can subscribe from Python, Node.js, Java and others to receive position data in real time. The serial output can be parsed directly in Python, C++ or Node.js as well.
How do I scale beyond the PoC?
Start with the 3-anchor Creator Kit, then widen coverage with the Expansion Kit, which adds 4 anchors and a gateway. A single PAN ID supports up to 30 anchors, and separate zones can run independently on different PAN IDs — so the hardware you use for a PoC carries through to deployment.
How do I order, and how long does shipping take?
Send us the form below or email [email protected] and we will reply with a quote, including shipping to your country, within 1 business day. In-stock kits are dispatched within 1–2 business days of payment via Korea Post; transit time varies by destination.
Do you help with installation?
Self-installation using the setup guide and documentation is the default. Paid installation consulting is available for business customers depending on the project.
Can I test the kit before buying?
Yes — testing is available at our office in Busan, Korea. Contact us at [email protected] to arrange a session.
What are the return and warranty terms?
Returns are accepted within 7 days of delivery if the product is unused, complete and undamaged. A 1-year warranty applies from the date of purchase, excluding user damage, non-recommended installation methods and consumables.
