CAST-SGX GPS Satellite Simulator

The SGX GPS satellite signal simulator from CAST Navigation provides the user with dynamic, repeatable GPS RF signals for use in the laboratory or in the field for a wide range of GPS applications. The SGX simulator is housed in a portable, lightweight handheld enclosure measuring 7 × 11× 3 inches and weighing just over 4 pounds.

The SGX replaces the CAST-SIMCOM simulator, a 17-inch, 50-pound simulator. The SGX is lightweight, portable, operates on AC or battery power, features 16 channels of L1 C/A- and P-codes, and is extremely accurate and repeatable. It is based on CAST technology that has been developed for use in the company’s larger military products.

The SGX is controlled via an intuitive touchscreen interface that allows the user to select start and stop scenarios, change screen views, and change satellite RF power levels while a scenario is running. Three test scenarios are delivered with the simulator.

XGen Scenario Generation Software. This optional software gives the user the ability to generate custom scenarios for use with the SGX. The software allows for complete control over GPS almanac, ephemeris, and all satellite error sources, including multipath. The user can select from a variety of vehicle types and simulate static or dynamic motion for land, sea, air, and space-based vehicles. The user may also employ antenna gain patterns and vehicle silhouettes.

GPSG-1000: Portable GPS/Galileo/SBAS Positional Simulator


GPSG-1000: Portable GPS/Galileo/SBAS Positional Simulator

Designed to be a versatile yet affordable satellite simulator, the GPSG-1000 is used by those validating and testing GNSS receivers in a variety of applications in the transportation, consumer electronics, aerospace, and military industry segments, to name a few. The GPSG-1000 is a single carrier, multi-channel GPS/Galileo simulator. Portable and ruggedized, it can be safely and confidently deployed in a variety of outdoor and indoor environments. The unit is available in a 6- or 12-channel configuration, and supports L1, L1C, L2C, L5, E1, E5, E5a, E5b, and SBAS (WAAS and EGNOS) signals.

The GPSG-1000 can be directly connected to a GNSS receiver under test. It can also simulate actual “open sky” situations, whereby the unit can generate its signals through the included antenna coupler system that isolates and transmits to the UUT’s antenna(s). Utilizing an integrated GPS receiver, the GPSG-1000 simulates actual time of day and date as well as the real constellation that would be available for navigation at that specific time. Multiple almanacs and route files can be saved to memory, enabling current and past history dynamic motion, constellation environment creation/recreation, and other troubleshooting capabilities. During any given static or dynamic simulation, space vehicle parametrics and health can be user controlled.

At less than 10 pounds, the GPSG-1000 features a touch-screen user interface that can be remotely hosted via an integrated Ethernet port. The unit uses a rechargeable, lithium-ion battery, enabling hours of untethered use, or can be used while the battery is recharging.

LabSat Turntable


LabSat, LabSat 2, SatGen v2

LabSat and LabSat 2 are record and replay multi-constellation GNSS simulators. Designed as lightweight, easy-to-use standalone systems, the LabSat range has the ability to provide and deliver solutions for a wide range of testing requirements. Equipped with pre-recorded test scenarios and the ability to record and replay the user’s specific scenarios, LabSat delivers precise and accurate test results — replicating real-world situations in the lab or testing facility.

The range also has the ability to record and replay data from a wide range of data sources, including vehicle CANbus, inertial sensors — such as gyrometers and wheel speed sensors — and reference receivers. A recent innovation is the LabSat Turntable Solution, which allows for the replay of dead-reckoning turn-rate signals to be played into a navigation device to simulate use through built-up areas and urban canyons. Both LabSat and LabSat 2 can observe all satellites in view; while LabSat observes GPS, Gallileo, and SBAS, LabSat 2 includes GLONASS and BeiDou-2.

Reliability of the gathered data can be assured when used together with SatGen v2, Racelogic’s simulation software. This scenario-generation software enables users to create scenario files based on user-defined trajectories, which can be replayed on LabSat. With SatGen v2, a scenario can be generated anywhere in the world, with position, route, speed, and time defined by the user. This high-performance software allows users to verify that their GNSS equipment performs as required in a variety of locations that maybe geographically remote or unavailable due to hostile environments.

GSS8000 Simulator

Spirent Federal Systems

GNSS Simulators

Spirent provides simulators that cover all applications, including research and development, integration/verification, and production testing.

GSS8000 (pictured). Spirent’s flagship simulator, the GSS8000, is fully approved for Y-code, SAASM, AES M-code, and SDS M-code testing. Spirent provides options and configurations for testing GNSS interference effects and interference mitigation techniques, such as integrated GPS/inertial testing, CRPA testing, and jamming/anti-jam simulation.

Spirent has delivered simulators that produce both legacy signals as well as modernized signals such as 2C, L5, and L1C. In addition to GPS, systems can include GLONASS L1/L2, Galileo, and Beidou-2, plus SBAS (WAAS, MSAS, and EGNOS) and Japan’s QZSS.
CRPA Test System. Spirent’s Controlled Reception Pattern Antenna (CRPA) Test System generates both GPS L1/L2 and interference signals; multiple GSS8000 chassis may be combined to coherently control up to seven antenna elements. Null-steering and space/time adaptive CRPA testing are both supported by this comprehensive approach.

GSS7790. Spirent’s GSS7790 Multi-Output Simulation System allows the signal from each satellite to be mapped to a separate RF output. These signals can then be fed to individual transmit antennas, which, when suitably deployed in an anechoic chamber, replicate the spatial diversity of satellite and jammer signals incident on the receiver antenna. Additional flexibility is offered as the signal is further split into its GPS L1 and L2 components, as appropriate.
