CAST-3000: Complete GPS/INS Integration Testing
CAST GNSS/INS simulators generate high-fidelity GNSS RF signals along with the coherent digital inertial signals that allow for the precise stimulation of the next generation of GNSS/INS navigation equipment. CAST’s GNSS/INS systems provide the highly precise system performance that is required to aid in the integration and testing of the next-generation of GNSS navigation system technologies. The 35-year-old company’s business focus is supplying GNSS/INS simulators, GNSS/INS test equipment, and GPS/INS support services to government and military avionics laboratories, prime contractors, GNSS receiver manufacturers and system integrators.
The CAST-3000 fully supports integration testing of GPS/INS navigation systems where the inertial sensor and GPS receiver are either tightly or ultra-tightly coupled. The CAST-3000 produces GPS RF signals coincident with simulated IMU sensor data that provide dynamic testing in the laboratory environment for military and government applications. CAST has worked closely with both Honeywell and Northrop Grumman over the past two decades in the development of the CAST-3000, which
-
- provides strapdown IMU measurement data synchronized with GPS RF data to the navigation system under test.
- contains a mature avionic sensor simulation Barometric Altimeter model.
- includes high rate inertial measurements with very high degree of fidelity to support testing of high-performance coupled systems.
- simulates sensors to provide the necessary fully coordinated, dynamic vertical channel aiding needed to maintain Kalman filter stability of the navigation system.
- includes years of development and refinement of the precise GPS/INS synchronization capability needed for simulation of aircraft dynamics.
- includes a complete 6-DOF motion generation capability.

Racelogic
LabSat 3 and LabSat Real-Time
LabSat 3 from Racelogic is a low cost, stand-alone, battery-powered, multi-constellation, RF record and replay device, designed to assist GNSS engineers in the development and testing of their products. By capturing live-sky RF signals, it enables repeatable and realistic testing to be carried out under controlled conditions, and is available as a record and replay, or replay only version; either one, two or three constellation types generate a single, dual or triple constellation file.
With standalone operation, LabSat 3 can be used in any outdoor location to create real-world scenarios for eventual replay back in the lab. As well as being able to simultaneously record or replay GPS, GLONASS, BeiDou, QZSS, Galileo and SBAS signals, it can log CAN bus, serial or digital data, embedded alongside the satellite information. This additional information can then be replayed alongside the GNSS output, with synchronization to within 60 nanoseconds. A 1 PPS signal can also be generated using the internal GPS receiver.
LabSat 3 can be used as a replay system out of the box with a set of 60 pre-recorded scenarios supplied as part of the package, recorded from various locations around the globe.
Additionally, SatGen software allows for scenario generation of user-defined trajectories, with precise control over velocity, heading, height and constellation profiles, giving the test engineer the ability to develop their product using simulations that would be difficult or impossible to record due to geographic location or safety constraints. NMEA and KML imports are supported.
New for 2016 is LabSat Real-Time, which allows for bench testing of GNSS devices where a current time stamp is required. SatGen V3 PC software generates a live signal stream to a LabSat RT unit which up converts the RF data from digital to analogue with less than one second latency. LabSat RT operates on any two of the three constellations of GPS, GLONASS and BeiDou.

Skydel
SDX: Software-Defined GNSS Simulator
Software-Defined Innovation
Skydel brings a new generation of GNSS simulators to the market. With the SDX simulator, signals are modulated by the graphics processing unit (GPU) as opposed to dedicated FPGAs found in traditional simulators. This allows new possibilities, such as adding signals and constellations without resorting to additional hardware. This design offers many benefits:
- The number of channels is defined by the GPU, eliminating the need to buy additional proprietary FPGA-based hardware whenever more channels are needed.
- Price per simulated channel is greatly reduced by using powerful, mass-produced off-the-shelf hardware such as graphic cards and software-defined radios. Moreover, the same hardware can be repurposed for numerous applications.
- Numerous hardware configurations provide flexibility ranging from single software-defined receiver (SDR) setups to racked instruments multi-element systems.
- SDX can be distributed over many computers, GPUs and signal generators to expand its capabilities.
Turnkey or Software-Only Solutions
SDX users can reuse their own SDR with the software-only solution, or choose a turnkey solution that comes with all the required hardware and a preconfigured laptop or desktop. Skydel can customize turnkey solutions to meet special requirements.
