Picking up your tracker at scrutineering is a formality; mounting it properly is another matter. Badly placed, a tracker transmits intermittently, punches holes in the live map and turns every remote sector into a worry for race control, and for the people following you from home. Here is how to install a GPS tracker on a race vehicle, bike, car or SSV: the placement, the bracket, the power and the pre-race check, from the competitor’s side.
Who supplies the tracker, and who mounts it
On most rally raids you do not choose the unit: the organizer imposes a single model for the whole field, usually rented for the length of the event and delivered already configured. How that rental works is covered in our guide to renting GPS beacons; at RaidLine, the beacons rented with the platform (Neyos units on cellular with satellite backup, YB Tracking devices on pure Iridium) arrive already paired: positions feed the app as soon as they are switched on.
The mounting, however, is on you. The unit and its bracket are handed out at administrative and technical checks, with placement instructions, and the scrutineers inspect the installation before the start. Your job as a competitor comes down to three things: a rigid bracket in the right place, an antenna that sees the sky, and power that lasts the distance.
Rule number one: the antenna must see the sky
A tracker does two things: it computes its position from GPS satellites, then transmits it over the mobile network or by satellite. Both operations go through antennas housed in the casing, and both demand the same thing: a clear view of the sky, with no conductive material above.
- Antenna facing up. The units have a mounting orientation: the antenna face (often the dome or the marked side) points at the sky, not at the wheel.
- No metal overhead. A roof panel, a boot lid or an aluminium plate acts as a shield. A tracker hidden under a bonnet or inside a boot will transmit poorly or not at all.
- Carbon counts as metal. Carbon fiber conducts electricity and blocks GPS and satellite signals almost as well as sheet metal. Put a carbon roof or panel above the tracker and the tracking degrades.
- Even more true on satellite. Trackers that transmit over Iridium or Globalstar need a genuinely open sky to get a message out. If your event crosses dead zones, antenna placement is the difference between continuous tracking and positions arriving in bursts: our article on GPS tracking without cell coverage explains why.
- Away from other antennas. Keep the tracker clear of the navigation GPS, the satellite phone and any other onboard antenna, to avoid interference between receivers.
Installing a GPS tracker on a bike
On a rally bike, space is scarce: the roadbook tower, the tripmaster and the regulation GPS already fill the cockpit. The tracker mounts on a rigid bracket bolted to the frame, the handlebar or the rear subframe, following the organizer’s instructions:
- Bolted bracket, never glued or strapped alone. An adhesive mount or a single zip tie does not survive a crash. Use threadlocker on the bolts, and a safety tie on top if the organization asks for one.
- Away from the exhaust. Heat degrades the casing and its battery. The rear subframe on the side opposite the exhaust is a classic spot.
- The SOS button usable with gloves on. After a crash you must be able to trigger the alert without removing your gloves, possibly injured. An SOS mounted under the seat is useless.
- Without obstructing navigation. The tracker must not mask the roadbook or the instruments. Our navigation and safety gear checklist helps organize the whole cockpit.
One last test before leaving the paddock: give the unit a firm shake by hand. If it moves, tighten it; what rattles in the paddock breaks in the special.
In a car: bolted plate, sky view through the windscreen, clean wiring
In a 4x4 or a closed buggy, the cabin protects the unit but complicates the sky view: the roof and the bodywork act as a shield. The placements that work:
- The top of the dashboard, against the windscreen. Glass lets the signals through, sheet metal does not: the antenna sees the sky through the windscreen. This is the most common spot for a bolted plate.
- The roll cage, up high. On an open or semi-open vehicle, a cage mount above shoulder line gives the best reception.
- The SOS reachable with harnesses tight. Driver and co-driver must both be able to reach the button without unbuckling. Test it seated, strapped in, helmet on: that is the position you will need it in.
- Protected wiring. If the tracker is wired to the vehicle’s circuit, the cable runs clear of the pedals and moving masses, sleeved, with a dedicated fuse. Tear a wire off in a special and the tracker silently falls back to its battery without you knowing.
The SSV and UTV case
The SSV stacks up the constraints of both worlds, and it is the vehicle where mounting mistakes are most common. The cage is open, so the sky view is good almost everywhere; in exchange, the unit takes everything: dust, mud, water crossings, vibration harsher than in a 4x4, and the pressure wash every evening at the bivouac.
- Up high on the cage or the dashboard, never on the floor: water and mud collect at the bottom of the cabin.
- Watch the roof panel. Many race SSVs run an aluminium or carbon roof: both act as shields. The tracker mounts forward of the roof, behind the windscreen if there is one, or on a cage bracket that clears the panel.
- Check the bolts every evening. SSV vibration loosens hardware faster than a car does. The bracket check belongs on the evening spanner list.
- Waterproof connectors. If the unit is powered by the vehicle, the connector must be sealed and face downward, to survive water crossings and the pressure washer.
To understand what changes between the three vehicle types on the tracking-hardware side, our comparison GPS tracker for a raid: 4x4, motorbike or SSV completes this guide.
Power: internal battery or vehicle circuit
On a bike, the tracker almost always runs on its internal battery. The sizing rule is simple: it must outlast your longest stage with margin, counting the wait at the start, liaison sections and the unexpected. Charge it every evening at the bivouac, like your phone.
On a car or an SSV, the safest configuration is wiring the tracker to the vehicle’s circuit with the internal battery as backup: the unit transmits as long as the vehicle runs, and keeps going for hours if the electrical circuit fails, exactly the moment race control needs to see you. Check with the organizer whether the power cable comes with the unit or is yours to supply.
The pre-race check, then every morning
A well-mounted tracker gets verified before the start, not during the first special:
- A full-scale test. Tracker mounted, engine running, cover a few kilometers and check that the position is coming through on the platform, which the organizer can see on the live tracking map. A fault found the day before gets fixed; on race morning it is too late.
- Never test the SOS without clearance. Pressing the emergency button triggers the real alert chain. If you want to test the SOS, ask race control first.
- The morning routine. Before every stage: the tracker’s lights, the battery level, the bracket bolts, the connector seated. Thirty seconds that spare you a day of holes in your track.
If this is your first event, mounting the tracker is only one step among many: our first rally raid guide walks through the whole competitor journey, from entry to finish.
Beacons delivered ready to mount
RaidLine rents organizers Neyos beacons and YB Tracking devices already paired to the platform: live map, SOS, low-battery and speeding alerts, replay. The competitor mounts them, the positions come through. Demo available on request.

Where do you install a GPS tracker on a rally bike?
On a rigid bracket bolted to the frame, the handlebar or the rear subframe, antenna facing the sky, away from exhaust heat, with the SOS button reachable and usable with gloves on. Never under the seat or in a bag.
Can you mount a GPS tracker under a carbon roof?
No. Carbon fiber conducts electricity and shields GPS and satellite signals much like sheet metal. The tracker needs a clear view of the sky: above the panel, on the dashboard behind the windscreen, or on the roll cage.
Should the tracker be wired to the vehicle’s battery?
On a car or an SSV, wiring the tracker to the vehicle’s circuit with an internal backup battery is the safest configuration. On a bike, the tracker usually runs on its own battery, sized to outlast the longest stage with margin.
Who supplies the GPS tracker on a rally raid?
On most events the organizer imposes and supplies the tracker, usually rented for the length of the race and delivered already configured. The competitor receives the unit and its bracket at scrutineering and mounts it following the organizer’s instructions.
