GNSS RF simulation, recording and playback

Simceiver™ GNSS RF Simulation, Recording and Playback Systems

Compact GNSS RF simulator systems combining selected-band recording, SDR software-receiver processing, 8-bit signal generation and controlled RF playback. The current USB 3 Simceiver A3-R2-U3 is available for individual configurations; the established single-frequency USB 2 A1-R1-U2 remains available for volume projects.

IP-Solutions Simceiver A3-R2-U3 compact GNSS simulator, recorder and playback system

Simceiver family

Select by RF scale and ordering model.

Both configurations integrate simulation, recording and controlled playback. A3-R2-U3 is the current individually configured USB 3 model; A1-R1-U2 remains available for standardized multi-unit deployment.

Simceiver A1-R1-U2

A proven one-board, single-frequency USB 2 Simceiver for universities, teaching laboratories, research groups and OEM applications requiring multiple identical systems.

One RF output, single-frequency operation
Integrated one-channel recording and playback
Defined, standardized USB 2 architecture

Available for volume orders; minimum order quantity applies

A four-RF solution is also available for broader multi-output tests. Please contact sales for configuration details.

Three independent operating paths

Simulation and live-signal recording are alternatives—not one mandatory sequence.

File-based simulation

Generate an 8-bit simulated signal file with ReGen. Reproduce it later as RF through Streamer and/or process the file directly with the bundled ARAMIS receiver or Borre's free MATLAB receiver.

Real-time simulation

Generate and transmit civil GNSS signals directly in real time through the 8-bit simulation path. No recording stage is required.

Live-signal recording

With A3-R2-U3, check the live signal with bundled ARAMIS before recording. SPS, NavIC and SBAS are supported. Record the selected band, then process it with ARAMIS or Borre's MATLAB receiver and/or reproduce it through the controlled RF playback path.

Recording and RF playback are separate operating modes. There is no real-time record-to-transmit relay path.

Selective baseband / digitized-IF architecture

Record the GNSS signal band required for the test—not unused wideband spectrum.

Receiver-relevant capture

Simceiver is configured around selected GNSS centre frequencies and receiver-test objectives. The recording preserves the complete signal mixture within the selected band for later software-receiver processing and controlled RF reproduction.

Receiver-matched 2-bit recording

Two-bit recording reflects the low-bit quantization commonly used inside high-performance GNSS receivers. For thermal-noise-dominated GNSS signals, additional recording bits can multiply data volume without improving a typical receiver-level test in proportion.

Software-receiver access

Bundled ARAMIS processing makes the recording an engineering dataset rather than an opaque RF archive. Users can verify acquisition and tracking before recording, then process simulated or recorded files with ARAMIS or Borre's free MATLAB receiver.

Manageable records

Signal-focused sampling and low-bit quantization keep recordings practical to store, transfer, inspect and reuse. The result is suited to iterative laboratory work rather than one-time bulk capture.

RF configurations

Dual-frequency, dual-scenario or standardized single-frequency operation.

The selected bands, sampling, bandwidth and software options are defined against the receiver and test objective. A four-RF solution is also available for broader multi-output tests.

Dual frequency

Combine two selected GNSS frequency bands at the SUM output for one vehicle scenario and receiver test.

Product positioning

Three platforms with distinct RF and commercial roles.

Both Simceiver models integrate simulation, recording and playback. Replicator provides four RF outputs and broader advanced-test capability; recording requires a separate recorder, while playback is available as an option.

Controlled record & playback

Integrated does not mean a live relay path.

Both Simceiver models contain recording and playback functions, but recording and RF transmission operate as separate modes. Saved signal data is checked and then selected for later controlled RF reproduction.

No real-time recording-to-transmission path.

Configuration enquiry

Choose the RF architecture before the option list.

For A3-R2-U3, tell us whether the requirement is dual-frequency or two-antenna / two-vehicle operation, together with the signals, dynamics, recording format and interfaces. For A1-R1-U2, tell us the single-frequency configuration, quantity and intended laboratory or OEM use.
