The distinction that matters
The main instrument reads live speed from the location service rather than waiting for a trip to start. That makes it possible to inspect a current reading without recording a session. Waymark also shows the state of the location fix, and it distinguishes a missing or stale reading from a live one. The displayed speed and the saved trip maximum answer different questions.
Check the GPS label before interpreting the number. Good, poor, acquiring, lost and denied states describe different conditions. A large numeral is still an approximate phone reading, not a calibration certificate. Configure units and alerts while stationary. Sound or vibration requires the relevant setting and supported device behaviour; neither should become the only cue you depend on.
Read the information in context
The last known reading is not a prediction of current movement.
- Read the lost-fix label
- Note any age indicator
- Wait for current location before relying on live values
What this does not establish
A journey passes through an area where fixes stop arriving. This is an illustrative scenario, not measured field-test evidence.
Compare readings only when they refer to the same unit and time period. A current display is not the same as an average over a whole journey, and a filtered number need not change exactly like a separate device. When investigating a surprising value, record whether a trip was running and whether the location state changed at the same time.
Quick reference
| Item | Meaning | Keep in mind |
|---|---|---|
| Acquiring | Waiting for usable location | Do not read an unavailable placeholder as zero |
| Poor | Limited location quality | Read the caution alongside the number |
| Lost | The fix is no longer current | A last-known value is not a prediction |
| Denied or off | Permission or location-service issue | Use the recovery action for the stated condition |
