GNSS Signal Repeaters & Re-radiation Systems
Bring live outdoor GNSS signals into laboratories, production areas and other controlled indoor environments. The MZ series receives authorized satellite signals through an outdoor antenna, conditions the RF path and redistributes them to defined indoor test areas without generating synthetic GNSS scenarios.

Deployment Architecture
Match the Signal Path to the Indoor Requirement.
Repeater deployment begins with the required signal type: live navigation coverage, bidirectional BeiDou communication, combined RNSS/RDSS operation or regenerated signals for specialized testing.
Live Navigation-Signal Coverage
Receives live multi-constellation GNSS signals outdoors and re-radiates them into a controlled indoor area.
Bidirectional BeiDou RDSS Communication
Transfers the outdoor S-band downlink indoors and forwards the terminal L-band uplink back to the outdoor path.
Integrated RNSS and RDSS Operation
Supports navigation-signal reception and bidirectional BeiDou communication in one indoor terminal workflow.
Regenerative and Hybrid Test Signals
Processes selected live navigation signals before indoor delivery for anti-jam antenna and receiver evaluation.
Where repeater systems are deployed
The exact architecture depends on the receiver type, building environment, signal path and test objective.
GNSS Receiver R&D Laboratories
Provide live satellite signals to indoor receivers, development boards and navigation systems.
Production and Final Inspection
Support receiver initialization, functional checks, production adjustment and final inspection.
Enclosed Integration Areas
Deliver GNSS availability inside workshops, vehicle bays and other spaces without direct sky visibility.
BeiDou RDSS Terminal Development
Support indoor development, production and maintenance of BeiDou short-message communication terminals.
Integrated Navigation and Communication

GNSS repeater system questions
The correct platform depends on signal type, indoor coverage, antenna architecture and whether the application requires transparent re-radiation, BeiDou RDSS communication or regenerative processing.
01 What is a GNSS signal repeater or re-radiation system?
A GNSS repeater receives live satellite signals through an outdoor antenna, conditions and amplifies them, and re-radiates them into a controlled indoor area. It allows receivers and navigation equipment to acquire real satellite signals where direct sky visibility is unavailable.
02 How is a repeater different from a GNSS simulator?
A repeater distributes live satellite signals and preserves the current external RF environment. A GNSS simulator generates controlled scenarios with defined time, location, motion and signal conditions. Repeaters are suitable for indoor access to live signals, while simulators support controlled and repeatable laboratory testing.
03 How is a repeater different from signal recording and replay?
Repeater systems deliver the live outdoor signal environment indoors. A recording and replay system captures RF signals for storage and later laboratory replay. Recording and replay is preferable when the same field event must be reproduced multiple times.
04 Which models are intended for live navigation signals?
MZ101 and MZ101B are intended for same-frequency distribution of live BDS, GPS, GLONASS and Galileo navigation signals. MZ101 supports standard navigation re-radiation, while MZ101B adds broader signal monitoring, an integrated touchscreen and expanded operational control.
05 What is the difference between MZ103 and MZ103A?
Both platforms support integrated navigation and BeiDou RDSS communication signals. MZ103 uses separate RNSS and RDSS antenna paths, while MZ103A integrates RNSS and RDSS through a unified antenna and distribution architecture. The correct choice depends on site cabling, antenna isolation, terminal power and coverage design.
06 When should MZ201 or MZ202 be selected?
MZ201 is a regenerative repeater for applications requiring signal regeneration and higher adjustable gain. MZ202 combines regenerative and same-frequency channels, making it suitable for mixed test architectures involving anti-interference equipment, standard receivers and other authorized navigation-system evaluations.
07 Can one repeater system cover multiple rooms or test zones?
Multi-room and multi-zone coverage is possible when the RF distribution network is engineered for the facility. The standard 50-metre coverage reference is not a guaranteed building radius. Cable loss, splitters, indoor antenna placement, wall attenuation, isolation and required signal level must be evaluated for each installation.
08 What information is required before selecting a repeater?
Provide the required constellations and signals, navigation or RDSS operating mode, room dimensions, number of zones, antenna locations, approximate cable lengths, terminal transmit power and local RF-compliance requirements. These details allow the antenna, gain and distribution architecture to be reviewed before a platform is selected.
Define the signal path before selecting the repeater.
Share the required GNSS or BeiDou RDSS signals, facility layout, antenna locations and indoor coverage objective. Our engineering team will help determine whether the project requires a live navigation repeater, bidirectional communication platform, integrated RNSS/RDSS system or regenerative architecture.
