Cast-5000 GPS wavefront generator
CRPA and Attitude Determination Receiver Testing
The CAST-5000 produces a single coherent wavefront of GPS RF signals to provide repeatable testing in the laboratory environment or anechoic chamber. The basic system generates four independent, coherent simulations that reference a single point and is upgradeable to support seven elements for CRPA testing. With an intercard carrier- phase error of less than 1 centimeter, the CAST-5000 is extremely accurate.
The system generates a wavefront of GPS when its GPS RF generator cards are operated in a ganged configuration. Each generator card provides a set of GPS satellites coherent with the overall configuration. Several RF generator cards may be utilized together, ensuring phase coherence among the bank of signal generator cards.
The CAST-5000 Controlled Reception Pattern Antenna (CRPA) tester allows a full end-to-end test of the antenna system. The CRPA antenna, antenna electronics and the GPS receiver can be tested as a unit with or without radiating signals.

LabSat 3 Wideband
LabSat is a cost-effective and intuitive GNSS simulator.
New to the LabSat range of GNSS record and replay devices is LabSat 3 Wideband, which continues with the established reliability, cost-effectiveness, and simplicity of operation that are the benchmarks of the LabSat system.
A recording bandwidth of 56 MHz allows for the capture of a very wide range of live-sky satellite signals:
- GPS: L1 / L2 / L5
- GLONASS: L1 / L2 / L3
- BeiDou: B1 / B2 / B3
- QZSS: L1 / L2 / L5
- Galileo: E1 / E1a / E5a / E5b / E6
- IRNSS: L5
- SBAS: WAAS / EGNOS / GAGAN / MSAS / SDCM
Depending on the desired bandwidth, recording resolution can be set to 2, 4, or 6 bit. Check out the GNSS frequency guide on the LabSat website — labsat.co.uk — to see exactly which signals can be recorded and at which resolution.
Even with this greatly increased capacity over the original LabSat 3, the new simulator remains extremely easy to use: one-touch recording, no connection to PC required, battery powered for up to two hours, and with a removable 1-TB solid-state hard drive that can be replaced in no time, the LabSat 3 Wideband is convenient to use. It measures a compact 167 x 128 x 46 millimeters and weighs 1.2 kilograms.
For product future-proofing, the soon-to-be-launched SatGen Wideband will allow for testing with signals not yet fully available, such as GPS L2C and L5 — further increasing the power and versatility of the new LabSat 3 Wideband.

BroadSim: The NAVWAR Simulator
BroadSim was developed to simplify advanced jamming and spoofing scenarios with Navigation Warfare (NAVWAR) testing in mind. Powered by Skydel SDX, a 1000-Hz GNSS simulator engine, BroadSim is able to simulate multiple vehicles, constellations, and code types (military and civil). BroadSim is ideal for supporting real-world field tests, NAVWAR testing and jamming.
Field Testing. Field testing GPS receivers to determine their performance and vulnerabilities in degraded or competing environments is becoming standard practice. BroadSim has proven to excel in field testing events due to its integrated GPS receiver allowing for built-in live-sky synchronization, four independent RF outputs, and a wide dynamic range with up to 0 dBm transmit power. A typical configuration for a live-sky field test would have BroadSim time synchronized to live sky, transmitting C/A, P, Y and M on L1 while simultaneously transmitting P, Y and M on L2 all at 0 dBm.
NAVWAR. BroadSim is great for NAVWAR testing because of how easy it is to use and configure multiple vehicles. Talen-X has carefully designed the simulator such that users can easily create true signals using two RF outputs and spoofed signals using the other two RF outputs. BroadSim’s graphical user interface (GUI) is intuitive and designed to meet the demand of NAVWAR testing.
Advanced Jamming. An innovative feature that has been added to BroadSim is the ability to generate jamming signals without any additional hardware. Using a simple interface, users can specify the jammer location, power level, waveform type and antenna pattern. BroadSim uses its 1000-Hz engine to compute the I/Q data incident on the user antenna for both the GNSS and jammer signals. This new paradigm of jamming simulation makes it easy to simulate complex jamming environments.
