Frequently Asked Questions
What does GNSS or GPS mean?
GNSS (Global Navigation Satellite System) is the umbrella term for all satellite constellations that provide global positioning.
GPS (Global Positioning System) is one specific system, owned and operated by the United States. Other constellations covered by GNSS are Galileo (EU), BeiDou (China), GLONASS (Russia), QZSS (Japan), NavIC (India).
Why doesn’t my GPS receiver work indoors?
The signals sent by satellites are incredibly weak by the time they reach Earth— the GNSS signals travel 24,000 kilometers from satellites. Signals are easily blocked or “absorbed” by dense materials like concrete, brick, and metal roofing.
How can I get GPS indoors?
GPS or GNSS can be brought indoors by using a GNSS repeater or active amplifiers and splitters.
- GNSS repeaters transmit the signal wirelessly to any device with an antenna.
- Amplifiers and splitters are suitable for wired devices with a physical GNSS port.
What is a GPS repeater?
A GNSS Repeater includes an Outdoor Antenna on the roof, a Coaxial Cable, and an Indoor Repeater Unit that re-radiates the signal inside.
Can I do indoor navigation with a GNSS repeater?
No. A repeater repeats the signal seen by the outdoor antenna. If you move inside, your “blue dot” on the map stays at the position of the outdoor antenna.
Where can I use a GNSS repeater?
Use cases include Fire Stations, Aircraft Hangars, Product Testing Labs, and Data Centers where live GNSS signal is needed continuously.
Can I have multiple GNSS repeaters?
Yes. You can distribute the signal from a single outdoor antenna to several indoor units using a splitter for multi-room coverage.
What are the benefits?
- Continuous availability: No long reacquisition times.
- Operational readiness: Vehicles ready immediately.
- Testing: Verify GNSS functionality indoors.
- Timing: Precise time synchronization.
Are GNSS repeaters legal to operate?
Yes, if you follow local regulations. Typically, you need a radio license from authorities like Ofcom (UK), Traficom (Finland), or BNetzA (Germany).
Can I install one myself?
Yes, but it is highly recommended to use a skilled installer to ensure the best performance and avoid interference issues.
