GPS World’s 8th annual Simulator Buyers Guide features tools, devices and software from leading providers.   CAST NAVIGATION JACKSON LABS TECHNOLOGY INC. OROLIA QASCOM RACELOGIC ROHDE & SCHWARZ SKYDEL SPIRENT FEDERAL SYSTEMS TALEN-X CAST NAVIGATION CAST-5000 GPS wavefront generator Photo: CAST Navigation 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 millimeter, 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. The CAST-8000 is a new simulator that merges both the CAST-5000 CRPA tester with a CAST-3000 EGI tester.

Micro-Transcoder GPS Simulator/RF-Modulator Photo: Jackson Labs The tiny 1-inch square Micro-Transcoder module allows glueless retrofitting of existing GPS equipment with secure and Assured-PNT (A-PNT) capability. It is the smallest, full-constellation, stand-alone, real-time 10-channel GPS simulator available from JLT. The unit is useful in upgrading existing legacy GPS receivers with external position, navigation and timing references such as INS, CSAC, SAASM, M-code, GNSS, eLoran or other alternative positioning and timing sources by simply replacing the legacy GPS antenna from an existing GPS system with the Micro-Transcoder RF output. The unit is based on the JLT CLAW GPS Simulator and RSR Transcoder technologies, and includes a general-purpose, stand-alone, full-constellation, 10-channel, real-time GPS simulator with integrated high-stability timing reference, as well as an internal GNSS receiver for monitoring the RF output signal for quality and accuracy. The unit will transmit a standard UTC time, position, velocity and heading GPS L1 C/A RF signal by simply applying 3.3V power to it. The Micro-Transcoder can also be operated as a generic GPS simulator with built-in GPS Disciplined Oscillator (GPSDO), and is supported by a free Windows application downloadable from the JLT website. The Windows application allows control of all the simulation aspects, creating and storing simulation vector commands and testing user equipment for leap-second and GPS week rollover event compatibility to identify weaknesses in user equipment. The unit does not require a connected PC to function. The Micro-Transcoder is also available mounted onto an evaluation board for easy evaluation. The unit transcodes baseband PNT NMEA signals into a GPS L1 RF signal with typically less than 100-ms latency. UTC 1PPS timing-transfer accuracy to the GPS RF output is typically better than 5 ns. The unit requires only 3.3V to operate, and setup, location and simulation vector file information can optionally be stored in its internal NV memory. sales@jackson-labs.com www.jackson-labs.com (702) 233-1334 [Back to top] OROLIA GSG-5/6 Series All Constellations, All Frequencies Photo: Orolia For those responsible for mission-critical PNT applications, the Orolia GSG series of GPS/GNSS simulators is an important tool to evaluate risk for jamming, spoofing or any other threat.
