What Does a Rally Tripmeter Do?
A rally tripmeter, sometimes referred to as a tripmaster or rally odometer, measures the distance travelled by a vehicle and displays the information in a format suitable for rally navigation.
Unlike a standard vehicle odometer, dedicated rally tripmeters are designed to support frequent distance resets, adjustments and calibration. This allows the navigator to compare the displayed distance with the information provided in a rally roadbook.
Depending on the model, functions may include:
- Total distance measurement for the complete route or stage.
- Interval distance measurement between roadbook instructions.
- Manual distance adjustment and resetting.
- Calibration to match a known reference distance.
- Current vehicle speed indication.
- Average speed information for suitable models.
- Stopwatch and time-of-day functions.
- Connections for external controls or remote displays.
- GPS-supported distance measurement on selected models.
Available functions differ between individual products. Always check the specifications of the chosen tripmeter before purchasing.

GPS Rally Tripmeter or Sensor-Based Distance Measurement?
One of the most important decisions when choosing a tripmaster is how the equipment will measure the distance travelled. Different systems use either an electronic vehicle signal, a dedicated distance probe or satellite positioning technology.
Sensor-Based Rally Tripmeters
Traditional electronic rally tripmeters can calculate distance from pulses generated by a suitable sensor or vehicle speed signal.
These signals are converted into distance using a calibration setting, allowing the tripmeter to calculate how far the vehicle has travelled.
The correct installation and calibration of the sensor are essential. Depending on the vehicle, this may involve a dedicated probe, a compatible electronic speed output or another approved signal source.
GPS and GLONASS Tripmeters
Selected Terratrip GeoTrip models use GPS and GLONASS satellite signals to support distance measurement. This can be particularly useful for vehicles where fitting an additional wheel or drivetrain sensor would be difficult.
GPS-based measurement can simplify certain installations, although signal availability and measurement performance depend on reception conditions and the surrounding environment.
Some GPS-enabled tripmeters also support external sensor inputs, providing additional options for configuring a rally navigation system.
A GPS tripmeter should not be confused with a conventional satellite navigation unit. Its primary purpose is distance and rally information rather than automatic turn-by-turn route guidance.
Tripmeters for Regularity Rallying
Regularity events often require competitors to follow a prescribed average speed or reach particular locations according to a defined schedule. Consistent distance and time information can be valuable when navigating these events.
A suitable regularity rally tripmeter may provide distance, current speed, average speed and timing information. Certain advanced models can also support more specialised regularity functions.
The correct equipment depends on both the event format and its rules. Some historic and regularity competitions restrict the use of electronic navigation aids or GPS-based equipment.
Before choosing a tripmeter for regularity rallying, always check which functions are permitted by the event organiser.
Classic Rally and Historic Roadbook Navigation
Classic car rallies frequently rely on roadbook navigation, where the co-driver follows route diagrams, distances and written instructions.
An electronic tripmaster allows the navigator to compare the actual distance travelled with the roadbook and make adjustments when necessary.
Fitting electronic measurement equipment to an older vehicle may require additional consideration. Classic cars do not always provide a directly usable electronic speed signal, making a dedicated sensor or GPS-supported system a possible alternative.
Always check the electrical compatibility, installation requirements and event regulations before fitting navigation equipment to a historic competition vehicle.
Calibration and Accurate Rally Distance Measurement
Correct calibration is essential for obtaining useful distance readings from a rally tripmeter, particularly when using a wheel or drivetrain sensor.
For many sensor-based systems, the normal procedure involves travelling a known distance and entering or calculating the relevant calibration value. The tripmeter then uses that setting to convert the incoming signal into travelled distance.
Distance accuracy can be influenced by factors including tyre dimensions, tyre pressure, sensor installation and the calibration procedure.
GPS-enabled models may offer additional calibration options, depending on their specifications.
Before a competitive event, it is advisable to check the tripmeter against a known reference distance and confirm that the selected measurement settings are appropriate.
Tripmaster Accessories, Sensors and Remote Displays
Installing and operating a rally tripmeter may require additional components. The correct accessories depend on the tripmeter generation, the vehicle and the intended navigation setup.

Choosing the Right Tripmaster for Your Rally Car
The ideal rally tripmeter depends on the event, the vehicle and the information required by the navigator. A straightforward distance meter may be sufficient for some rallies, while regularity competitions can benefit from additional speed and timing functions.
Before selecting a tripmaster, consider:
- The type of event: navigation rally, regularity, historic rally or road survey.
- The distance information and display resolution required.
- Whether satellite positioning is permitted or preferred.
- The availability of suitable vehicle speed or distance signals.
- The need for current and average speed information.
