3-Space™ Data Logger Family
If it moves, we can track it. The 3-Space™ Data Logger family puts motion tracking, data logging, and power in one end-use-ready unit: no external logger, no tethered power, no integration project. Attach it and start capturing — indoors, outdoors, and everywhere GPS can’t reach.
Which Data Logger fits your work?
Three models, one question: how does your data need to move?
H3: 3-Space™ Data Logger Nav — adds BLE + GPS. From $599
- Everything in the Link, plus onboard GPS
- GPS outdoors, EEPTS indoors: positioning that doesn’t stop at the door
- Position and motion on one timestamped timeline, one device
- Heading referenced to true, magnetic, or grid north
3-Space™ Data Logger Link — adds BLE wireless streaming. From $499
- Everything in the Core, plus Bluetooth Low Energy (BLE)
- Stream real-time data and access logged files, cable-free
- Dual auto-selecting accelerometers (±2 to ±320g) standard
- Built for wearables, on-body analysis, and untethered deployments
3-Space™ Data Logger Core — standalone logging. From $399
- 10 DOF sensing with onboard barometer
- EEPTS™ GPS-denied pedestrian tracking, standard
- Onboard micro-SD logging, high-speed USB-C
- Low-Range or High-Range (±320g) accelerometer options
Standard on every unit: tracking where GPS can’t go
Every 3-Space™ Data Logger ships with our EEPTS™ pedestrian tracking engine built in. Developed through defense-funded R&D, EEPTS delivers positional tracking where GPS can’t reach — indoors, underground, in dense urban environments, and where GPS is jammed — with floor-level altitude changes tracked via the onboard barometer. No beacons, no external infrastructure. Capability that typically requires a separate software license is simply how these sensors work.
Precision engineered for real-world conditions
Ten degrees of freedom fused through Yost Labs’ proprietary QGRAD3™ filtering, which outperforms Extended Kalman filtering with lower latency and lower computational overhead (selectable EKF included). ±1° dynamic orientation accuracy, update rates to 2000Hz, 10,000g shock survivability, and a -40°C to +85°C operating range. Every model includes a rechargeable battery (up to 10 hours Standard Profile, up to 20 hours Long-Life), and ships in Portable or Screwdown/Strapdown form factors.

Mount the clip, not the logger
The $15 Quick-Mount Kit turns any Portable 3-Space™ Data Logger into a repositionable mounted sensor: screwdown and strap clips with a keyed one-way fit, so the sensor seats in the same orientation on every swap. Fix a clip at every measurement point and rotate loggers between them — $150 instruments ten stations.

If it moves, we can track it
From GPS-denied navigation to pediatric medical devices to the largest naval vessels, our engineers have solved motion tracking problems no datasheet anticipated. We conduct application-specific R&D for your domain, building on our proven COTS platform or engineering one that doesn’t exist yet. Bring us the requirement everyone else said was too hard.
