FAQ
What technologies can replace GPS for indoor navigation?
Systems using Ultra-Wideband (UWB), dedicated RFID networks, or pre-mapped Wi-Fi fingerprinting can provide indoor positioning, but each has specific range, cost, and update rate trade-offs that must match operational re...

What are the operational impacts of indoor GPS signal loss?
GPS signal loss leads to misrouted assets, delayed turnarounds, compliance audit mismatches, workers reverting to memory or paper, and invisible routing inefficiencies like pallets getting staged in wrong zones.

Why does GPS navigation fail in large warehouses and airports?
Standard GPS signals cannot penetrate dense warehouse roofs or airport terminal structures, creating absolute dead zones where GPS becomes unavailable for indoor navigation.

When is it a device problem versus a carrier problem?
If location jumps or delays are inconsistent across identical devices on the same vehicle, it's likely a carrier coverage issue. If all the new 5G devices on a carrier show the same lag, but older 4G devices do not, then...

How many vehicles trigger 5G scale problems?
Problems emerge not at a specific vehicle count, but at data concentration. When 50+ devices in one yard all request high-frequency updates at the same time, carrier network prioritization can throttle some, which comple...

What is the biggest hidden risk with 5G fleet tracking?
Signal handoff failure in transition zones. A device can show strong signal but actually be stuck between towers, reporting its last known location for minutes. That creates false 'real-time' data that seriously misleads...

Does 5G make GPS location itself more accurate?
No. 5G improves data transmission speed and latency, but the actual GPS satellite fix accuracy comes from the device's GNSS chipset. Faster data just gets an accurate—or inaccurate—fix to your screen quicker.

When should we abandon fixing our RTK setup and redesign?
A redesign becomes mandatory when positional latency exceeds what your control system can tolerate, when signal reliability in your operational zone dips below 95%, or when compliance logging shows inconsistent data that...

Can I scale an RTK tracking system from a pilot to a full fleet?
Scaling is challenging as it introduces shared network resource contention, more data stream management complexity, and magnifies any tiny latency issue. Often, you need a redesigned data infrastructure, not just more de...

What causes RTK GPS to fail for autonomous vehicles?
Failure usually comes from a few places: correction signal interruption, network latency in the data link itself, and integration delays where the accurate position just isn't processed fast enough by the vehicle's contr...

How accurate is RTK GPS in real-world driving conditions?
Real-world RTK accuracy is conditional. You might get 1-4 centimeters with a perfect signal, but it can degrade to several meters the moment the correction signal drops—which happens near tall buildings or under dense tr...

Does having more satellites always mean better tracking accuracy for fleet vehicles?
No, more satellites don't always guarantee better accuracy. A device might see 20 satellites from one constellation but still experience location drift of 50+ meters if that constellation has issues like regional jamming...
