LabSat 4 is a GNSS satellite navigation signal recording, replay and simulation device that makes the recording, replay and simulation of advanced Global Navigation Satellite System (GNSS) test scenarios simple. The device records GNSS and other RF signals at a 12-bit I&Q quantization level, supports unrestricted recording across a wideband tunable frequency range including L1, L2, L5, B3, E6 and the S band, with each RF channel offering a flexible 10-60 MHz bandwidth to reduce the file size generated during scenario recording.

LabSat 4 supports multi-system synchronization, tightly synchronizing the recording and replay functions of two LabSat 4 systems, making it suitable for dual-antenna testing. It can also simultaneously record additional signals such as two CAN channels, one CAN FD channel, one RS232 channel and digital level signals while recording GNSS signals. With the SatGen software, the device performs real-time multi-frequency RF simulation based on user-defined static and dynamic scenarios, and provides MGC/AGC gain control and high-speed data transmission.

Product Features

·Data quantization level: 1/2/4/8/12-bit I&Q (LabSat 4); LabSat 4 Core is 1/2/4-bit; LabSat 4 Lite is 1/2-bit.

·3 RF channels with selectable center frequency, variable bandwidth of 10-60 MHz per channel, and sampling frequency automatically adjusted to suit the bandwidth (10-61 MHz).

·Supports satellite constellation signals such as GPS (L1/L2/L5), Galileo (E1/E5a/b/E6), GLONASS (G1/G2/G3), BeiDou (B1/B2a/b/B3), QZSS, NavIC, SBAS and Pulsar; more high/low L-band and S-band signals can be configured through the web interface.

·A built-in variable attenuator provides an adjustment range of +20 dB to -69 dB during replay.

·Multi-system synchronization, suitable for dual-antenna testing.

·Can synchronously record 2xCAN, 4x digital, 1xRS232 and 1xCAN-FD channel signals (not available in the LabSat 4 Lite version).

·Supports user-defined simulation capability through an optional simulation software license (SatGen real-time simulation).

·Storage: 1TB SSD (Lite) / 4TB SSD (Core) / 7TB SSD (LabSat 4); gigabit Ethernet data transmission; all versions are equipped with an 8GB SD card (for firmware upgrade only) and a removable battery pack.

·Dimensions 167 × 137 × 52 mm, weight 1.45 kg (including internal battery and SSD), operating voltage DC 8-30 V.
