Choose based on your hardware and workflow, not a blanket accuracy claim. QuestLHSync uses a Quest headset’s cameras to observe SteamVR 2.0 base-station flashes; Space Calibrator’s standard workflow aligns a device from each tracking system by holding them together and moving them through different orientations. If you have SteamVR 2.0 stations and a supported Quest setup, QuestLHSync may fit without a headset-mounted tracker. Choose Space Calibrator when its mixed-device workflow suits your gear or you specifically want continuous calibration with a tracker mounted on the headset. No controlled head-to-head test establishes that either is more accurate overall.
Check compatibility before choosing
Start with the headset, base-station generation, available controllers or trackers, and network setup. The projects describe different methods, and their compatibility statements are not independent certification.
| Decision point | QuestLHSync | Space Calibrator |
|---|---|---|
| How it calibrates | Headset cameras observe SteamVR 2.0 base-station flashes; the project says alignment continues while playing. QuestLHSync README | Standard calibration aligns selected devices from the two tracking systems while held together and moved through orientations. Its listing also describes continuous calibration with a tracker attached to the headset. Steam listing |
| Base stations | Requires SteamVR 2.0 base stations; 1.0 is unsupported. QuestLHSync README | The Steam listing describes broader SteamVR-compatible use cases but does not state the same 2.0-only requirement. Check exact device support before relying on it. Steam listing |
| Headset claims | README lists Quest Pro as tested; Quest 3 and Quest 3S as untried. It also documents a Steam Frame installation route, not an independent performance test. QuestLHSync README | Listing describes Quest/Pico mixed-device use, but is not a per-model test report. Steam listing |
| Extra hardware | At least one Lighthouse device must be powered on. The stated method does not require a tracker mounted on the headset. QuestLHSync README | Standard calibration uses a controller and tracker together; continuous mode calls for a tracker attached to the headset. Steam listing |
| Platform and network | Windows with SteamVR; headset and PC must be on the same local network. QuestLHSync README | Steam listing specifies Windows 10/11 and SteamVR-compatible devices. Steam listing |
Which method fits your setup?
Choose QuestLHSync when its requirements match
- You have SteamVR 2.0 base stations, a Windows PC running SteamVR, and a Quest Pro or are willing to try an untried Quest 3 or Quest 3S setup.
- Your headset and PC share a local network, and at least one Lighthouse device is powered on.
- You prefer the camera-based method and do not want to mount a tracker on the headset for calibration.
The project says first acquisition takes about half a minute. It advises looking around so the cameras see both stations and suggests wearing a tracker or holding a controller while the stations are first identified. It recommends bringing a third station into view: its documentation says three visible stations let its reference frame be leveled with headset gravity, while with two stations the devices’ accelerometers level it as they move. These are the project’s instructions and explanation, not an independent performance measurement. QuestLHSync README
Choose Space Calibrator when its device workflow fits
The Steam listing names use cases including full-body trackers or Index controllers with Quest/Pico, and Vive Ultimate Trackers with SteamVR headsets. The standard procedure relies on selecting one device from each tracking system, holding them together without letting them slip, then moving and rotating them slowly through varied orientations. The upstream OpenVR-SpaceCalibrator README says calibration saves a profile and applies it as devices turn on. Its instructions may not map exactly to every fork’s interface or behavior.

#1 Best Overall
- Includes One base station and one power adapter per order
- Fits standard threaded mounting points
- Cord: 8' 2'' L
- Compatible with Vive Pro, Vive Pro Eye, Vive Pro 2 and Vive Cosmos Elite headsets
If you want Space Calibrator’s continuous mode, its Steam listing describes using a tracker attached to the headset. That is a distinct option from the standard paired-device calibration workflow; confirm that your tracker and headset combination is supported before setting it up. Space Calibrator Steam listing
Do not run two pose-correction tools together
QuestLHSync explicitly warns users to turn off Space Calibrator, OpenVR-SpaceSync, or any other software that adjusts Lighthouse device poses. Its README explains that two tools correcting the same devices can fight each other. Disable the other correction driver before trying QuestLHSync, rather than attempting to combine both methods.

- VR0572 Japan Authorized Distributor Product, Manufacturer Direct Warranty 1 Year
- Base station for SteamVR 2.0 Recommended for upgrading from the 1.0 environment or adding to a 2.0 environment
- The room scale VR is recommended to use at least 2 base stations. We recommend buying 2 or more when purchasing new models to improve functionality with the inside out format HMD
- Multiple uses for more precise tracking. With 4 units of maximum configuration, you can build a 10m x 10m room scale
- This product should be used with 2.0 standard base stations (with additional setup) and controllers. (It is not compatible with the 1.0 standard products at the same time or mixing)
Account for drift and the limits of the evidence
The upstream OpenVR-SpaceCalibrator README cautions that inside-out and Lighthouse tracking can drift after extensive movement around a room, and that wireless Quest use may require recalibration. It advises recalibrating after changes to the space; for wireless setups, its slow or very slow modes may reduce initial error. These are upstream project instructions, not a guarantee that every fork has identical controls or results. OpenVR-SpaceCalibrator README
QuestLHSync describes its own correction approach, but the available project documentation and Steam listing do not provide a controlled accuracy comparison or independent stability measurement. There is therefore no supported basis for declaring one method more accurate overall. Treat compatibility and behavior as project-stated, and judge the choice by your devices and workflow.

QuestLHSync has a local-network privacy consideration
According to its README, the QuestLHSync headset-side service responds to requests from anyone on the local network without authentication. It sends camera-derived bright-spot positions, camera calibration, headset serial number, model, and firmware, but not camera images. Consider whether that local-network behavior is acceptable in your setup. QuestLHSync README
