Mini GPS
Global Foxcom’s Mini GNSS Repeater is a compact coaxial repeater module for re-transmitting GNSS signals indoors across facilities that require reliable positioning, navigation, and timing signal availability. The module supports GPS, GLONASS, Galileo, and BeiDou, with calibrated gain adjustment, onboard RF filtering, antenna health monitoring, and protection against over-gain or oscillation conditions.
Features & Benefits
- Filtered GNSS frequency range from 1164–1610 MHz
- Calibrated gain range from 0-30 dB in 1 dB steps
- Low noise figure below 3 dB for strong RF performance
- Return loss greater than 10 dB
- Coupling port gain of +4 dB for daisy-chain expansion
- Two output ports supporting one or two indoor antenna zones
- Indoor coverage up to 1500 m² per unit
- Over-gain and oscillation detection for signal protection
- Outdoor antenna monitoring for open or over-current conditions
- Compact 130 x 60 x 25 mm module with TNC female RF connector
The Mini GNSS Repeater is designed for facilities where GNSS signal distribution needs to be controlled, scalable, and easy to deploy. Its calibrated RF gain DIP switch array enables precise coverage adjustment, while the embedded band-pass filter helps block unwanted off-air signals before they are re-transmitted indoors. When antenna placement is limited or wider indoor coverage is required, multiple modules can be connected in series through the coupling port to build a larger GNSS distribution network. The coupling port can also carry DC power, enabling one power supply to support multiple units in a daisy-chain layout.
For aviation and large-facility environments, the Directional RHCP variant helps support testing of aircraft navigation systems inside hangars or similar indoor spaces. The system is suitable for aircraft hangars, border surveillance sites, fire and police stations, tunnels, data centres, fleet management facilities, military bunkers, and manufacturing environments.
