RaceBox
RaceBox Mini S
25 Hz GPS that turns your phone into a precision lap timer.
Your iPhone updates its position about once a second. A RaceBox Mini S updates 25 times a second using four satellite systems at once, so TRACK sees exactly when you cross the timing line and how you used every metre of the corner.
01What it adds to TRACK
What it adds to TRACK
- 01
Timing you can trust
In TRACK’s timing tests on simulated laps, 25 Hz input cut the median lap-time error from 0.037 s (phone GPS) to 0.007 s. Every lap still shows its own uncertainty.
- 02
Sharper sectors and deltas
More position samples make the live delta steadier and sector splits fairer when laps are close.
- 03
Traces worth studying
Braking points, minimum corner speed and lines come out smooth enough to compare lap against lap.
- 04
Phone stays cool
The RaceBox does the satellite work; the phone can focus on video and the dash.
02How it connects
How it connects
- 1Charge the RaceBox and place it with a clear view of the sky (dash top or roof area).

04iPhone & Android
iPhone and Android
Bluetooth LE, in the iPhone app (awaiting hardware validation).
Android app planned. Bluetooth LE works the same way on Android.
The TRACK iPhone app is in beta. The Android app is planned.
05Where it stands
Tested, pending, and good to know.
- Decoder built from RaceBox’s published protocol and tested on recorded data.
- Clock alignment over Bluetooth tested in TRACK’s test suite.
- A physical unit still has to confirm the protocol field layout on current firmware.
- Use the RaceBox app for firmware updates; TRACK doesn’t update the device.
