Multiband GPS Wavefront Simulator (PDF)
(GPSS-MBW-008-06)
These units are similar to the dual frequency wavefront simulators with the additional bands at L5 and L2C signals.
Dual-Frequency Multichannel RF Signal Simulator for C/A, P, and M-codes (PDF)
(GPSS-DF-003-04/GPSS-DF-004-04)
These self-contained units simulate high-fidelity multichannel C/A, P, and M-code signals at L1 and L2 bands. Its control is available over all aspects of the signal generated using PRN, Power Level, Doppler, and signal/message content, etc.
The signal generator uses the software-based architecture hallmark of CRS's other simulators and receivers. It provides unprecedented accuracy and flexibility, and offers unlimited vertical upgrade.
The flexibility is reflected in the supplied software that allows an operator interactive mode or fully integrated mode using the supplied 'C' programming libraries. It supports synchronization to other systems. All the signals and internal signal structure can be monitored in real-time.
Multiband (L1, L2, L5) Multichannel GPS Signal Generators (PDF)
(GPSS-MB-006-06/GPSS-MB-007-06)
These units are simular to the dual frequency units with additional L5 band and L2C signals.
Multichannel GPS/WAAS Signal Generator (C/A code) (PDF)
(GPSS-CA-002-04)
This self-contained unit simulates high-fidelity
C/A code signal for up to 12 satellites at any time. It
generates GPS L1 C/A code signal and a Wide Area Augmentation
System (WAAS) signal and can test and help simulate GPS
systems. The signal generator is available in both rack-mountable
and tabletop configurations.
Multiband GNSS Wavefront Simualtor (PDF)
(GNSS-MFW-011-07)
This modular simulator provides comprehensive signal coverage for all GNSS signals in space. Modular units for GPS, Galileo, Glonass, EGNOS, SBAS, etc. are provided in order to seamlessly integrate with each other in both digital and analog domains. Additional modules such as LAAS, IMU emulator, high dynamics jammer/interferer, etc. also integrate with the system providing a truly comprehensive simulation system never attempted before. The simulator is housed in a 19 inch rack and different modules are interfaced through versatile combination modules, providing both digital and RF outputs at multiple antenna ports. A built-in calibrator ensures the precision to an unprecedented accuracy of 1 mm.
The entire simulator is operated using a highly evolved software interface enabling a variety of platform maneuvers, complex environmental simulation, receiver and satellite anomalies, and almost every possible modification in the signal structure. Yet the user interface is extremely simple and intuitive with comprehensive graphical displays.
Galileo Signal Simulators (PDF)
(GALS-MF-009-06: E5ab, L1, E6, Single Antenna/GALS-MFW-010-07:
E5ab, L1, E6, Wavefront)
Galileo signal simulators (for single antenna and multiple port wavefront generation) provide the same class of performance in terms of accuracy, flexibility, versatility, and user friendliness as in our GPS systems. The phase accuracy is held at the 1 mm level.
These simulators provide RF signals in all the three bands. The RF ports are available separately. A combined output with reasonabily high dynamic range is also available at the front panel (7 such outputs are provided in the wavefront generator)
