GNSS Repeater Kit for Indoor Positioning (GPS/BDS/GLONASS, 30m Cable, 50dB)

A repeater for places where GPS cannot reach

GNSS signals rarely get through roofs and walls, so a device inside a warehouse, factory or lab may never get a fix. This repeater kit solves that by receiving the signal with an outdoor antenna and re-transmitting it indoors through a second antenna, improving positioning inside enclosed spaces.

The kit supports GPS, BDS and GLONASS, and the amplifier boosts signal strength by 50 dB. It is used for asset tracking, indoor navigation and precision timing, as well as for testing GNSS devices in a workshop.

What is in the kit and how to use it

The package contains the GNSS signal transfer main unit, a GNSS antenna, a 30 m GNSS cable, a transmitting antenna and a power adapter. The product title lists a 30 m cable while one feature line says 25 m, so check the length when it arrives.

Place the receiving antenna with a clear view of the sky, run the cable to the indoor unit and position the transmitting antenna where you need coverage. Keep the two antennas well apart so the amplifier does not feed back on itself, and comply with local rules on re-radiating navigation signals.

Who it is for

Warehouses, factories, laboratories and test benches that need to run GNSS devices indoors. The seller offers a 14 day replacement warranty for manufacturing defects.

Installing safely

Mount the receiving antenna on a roof or high window where it has a good view of the sky, and route the cable without sharp bends. Keep the receiving and transmitting antennas as far apart as the cable allows, because a repeater that feeds its own output back into its input will oscillate. Test with a phone or GNSS receiver indoors to check that the coverage matches your needs.
