Signals & constellations
Generate the required civil GNSS signals and frequencies within one repeatable scenario and receiver test definition.
GPS, Galileo, GLONASS, BeiDou, QZSS, NavIC and SBAS simulation
ReGen™ GNSS RF Simulator Systems
Software-defined GNSS RF signal generation for multi-constellation receiver development, repeatable laboratory testing, dynamic simulation and specialized multi-output experiments.
Replicator ReGen-based GNSS RF simulator
ReGen software
One scenario engine. Several forms of output.
ReGen defines the signal environment, vehicle motion and receiver test conditions independently of the final hardware configuration.
ReGen-DIF can generate files for ARAMIS or a user SDR without RF hardware. With a Replicator chassis, the same scenario engine provides real-time RF for ARAMIS or an off-the-shelf conventional receiver, including dynamic signal and power control.
Test capabilities
Control the conditions that are difficult to repeat outside.
Motion & timing
Exercise static, vehicle, airborne, space and customer-supplied trajectories with external timing and trigger integration.
Propagation & errors
Introduce controlled atmospheric effects, multipath, antenna behaviour and measurement errors for comparative testing.
Adverse signals
Build controlled interference and spoofing experiments for receiver evaluation and multi-antenna processing research.
System family
Select by test architecture, not by a fixed package.
These names identify the principal system roles. RF cards, output count, signal set, dynamics and software options are defined in the final configuration.
General-purpose GNSS RF simulator
Replicator
The principal ReGen hardware platform for receiver development, verification, production and acceptance testing. RF architecture, outputs and interfaces are configured for the required test program.
- Static and dynamic receiver tests
- Multi-constellation, multi-frequency scenarios
- Reference clock, trigger and 1PPS interfaces
Multi-output and multi-antenna testing
Ninja
A ReGen configuration for controlled interference, spoofing, antenna-array and CRPA experiments requiring several coordinated RF outputs and defined spatial signal conditions.
- CRPA and adaptive-processing experiments
- Interference and controlled spoofing scenarios
- Direction-dependent and multi-antenna tests
Integrated compact system family
Simceiver™
The Simceiver family integrates ReGen simulation, recording and controlled RF playback. Simceiver Two-RF supports dual-frequency or two independent vehicle scenarios; Simceiver USB-2 provides a mature single-frequency volume configuration.
- Two-RF and single-frequency USB-2 models
- Integrated recording and controlled playback
- No real-time record-to-transmit path
Digitized-IF generation
ReGen-DIF
A digital-output configuration for receiver and signal-processing development where the required interface is digitized IF rather than an RF connection.
- Defined digital sample formats
- Algorithm and baseband development
- Repeatable data-driven testing
Controlled record & playback
Simceiver™ integrates recording and playback through separate operating paths.
Simceiver Two-RF records up to two RF inputs; Simceiver USB-2 records one single-frequency input. Both models reproduce saved data through their integrated playback path, while recording and transmission remain separate operating modes.
Simceiver recorder
Two RF or one USB-2 input
Saved RF data
Simceiver playback
Two RF or one USB-2 output
No real-time recording-to-transmission capability.

Integration
Built around the receiver and test bench.
ReGen systems can be configured for software-only digitized-IF, compact two-RF work with Simceiver, full rack-mount RF generation with Replicator, or controlled playback of saved signal files. External frequency reference, 1PPS, trigger, trajectory, inertial, automation and HILS interfaces are defined against the intended experiment.
- Bench, rack and customer-specific hardware
- Single- or multi-output RF architectures
- ARAMIS, user SDR and conventional-receiver test paths
- External clock, 1PPS and trigger connections
- GNSS–INS and hardware-in-the-loop integration
- Scenario, automation and customer software interfaces

Independent scientific use
LEO spaceborne-receiver simulation.
ReGen was used by Prof. Pavel Kovář and colleagues in work for an ESA project to simulate GNSS signals for a LEO spaceborne receiver. Prof. Kovář also reported using ReGen for testing LEO satellite GPS receivers.
Configuration enquiry
Define the signals, outputs and test objective first.
Tell us the receiver, constellations and frequencies, dynamics, interfaces, number of RF outputs and intended acceptance method. We will separate the standard configuration from customization and NRE.
