The highly accurate simulator can be used as an embedded module to transcode modern GNSS or inertial navigation system (INS) position, navigation and timing signals including SAASM and M-code into legacy GPS RF signals. This capability allows retrofitting any existing legacy GPS receiver to the latest Assured-PNT capability. It can also be used as a GPS firewall to automatically detect and mitigate spoofing and jamming events. RSR transcoder GPS simulator for retrofitting existing legacy GPS equipment to any GNSS, INS and atomic holdover capability The size of a postage stamp, the RSR Transcoder is based on the Jackson Labs CLAW simulator technology and is designed to be integrated into systems requiring retrofit of existing GPS legacy equipment with INS and atomic clock holdover capability, as well as the latest GNSS capability such as Galileo, GLONASS, BeiDou, SAASM, M-code and CSAC technology. Because the RSR Transcoder is fully self-contained, it also can work as a generic stand-alone GPS simulator for manufacturing environments or laboratory use. It is compatible with various external MIL-STD GPS receivers for glueless integration into existing vehicles by replacing the existing GPS antenna with the RSR Transcoder connected to an external GNSS receiver and optional high-performance INS. The RSR Transcoders ability to convert latest-generation GNSS receiver NMEA information into legacy GPS RF signals can also be used to upgrade low-performance legacy GPS receivers with modern –167 dBm and SBAS tracking capability for indoor reception and increased PNT accuracy in challenged environments.

The Constellator product is available in different ranges, from an entry-level unit supporting L1C/A up to a six-signal-frequencies/200 channels rack, supporting the most demanding configurations. Constellator is used extensively in the aeronautic, space and defense industries, where the requirements are highly demanding. Constellator has been carefully evaluated and selected by major industrial companies and agencies worldwide, and is used to test aircraft receivers, spacecraft, launchers and similar systems for defense and armies. Particularly in the space domain, Constellator implements the most accurate models (earth gravity, drag, etc.) needed to achieve “meter-precision” in standalone mode around a complete orbit. Constellator is based on modern, powerful software-defined radio (SDR) systems, which make it capable of extreme adaptability and upgradeability after purchase, even without any hardware upgrade. Though a high-end simulator, it is cost-effective because of its software-based architecture; instead of requiring one RF stage per signal, it requires just one per frequency band used. The Echo Record and Playback unit allows users to record real-life signals and environments and replay them in the laboratory, which is always more realistic than any simulation. Echo is typically used to replay predefined complex and very long realistic scenarios, avoiding the need to use costly satellite simulators for long-run tests or for production tests. Echo offers three RF channels of 100-Mhz bandwidth each, 16 bits I, 16 bits Q, and more than 10 hours of record and replay duration. As such, it is high-end record/replay equipment, offering high-end replay fidelity. www.syntony-gnss.com Email: François Goudenove, chief sales officer, francois.goudenove@syntony-gnss.com (ask François for the contacts of distributors in the U.S., Europe, India, China, South Korea, Japan.)
