OEM Time & Frequency Reference GNSS master clock and NTP/PTP time server VersaSync is a high-performance GPS master clock and network time server that delivers accurate, software configurable time and frequency signals under all circumstances, including GNSS-denied environments. Its compact size and high level of ruggedization make VersaSync suitable for mobile applications in harsh environments. Its small footprint allows for easy integration of the time and frequency functionality into systems architecture. VersaSync accommodates an OCXO, a high-performance OCXO or a CSAC oscillator, allowing it to maintain frequency and time accuracy for long periods of GPS/GNSS outage. It can be re-synchronized by an external reference. VersaSync is available with a C/A L1 GPS receiver or with an L1/L2 SAASM receiver. An extension slot accommodates additional timing interfaces. VersaSync physical inputs and outputs are software configurable and can adapt to various application requirements. I/O pins can be configured as TTL, 10 V pulse, RS232, RS485. This allows VersaSync to provide a high number of outputs of the same type, while still fitting into a small form factor. If the combination of software configurable outputs is not enough, VersaSync can accommodate an option board (within the same form factor), designed to customer requirements. Because of its high level of ruggedization, VersaSync provides exceptional intrinsic reliability. Strong status monitoring capability, either locally or remotely, allows quick fault diagnoses. An internal, exportable log can be accessed. Verasync Attributes Low size, weight and power Ruggedized (MIL-STD-810G) High versatility with software configurable inputs/outputs Design can be efficiently customized to match specific customer requirements Easy integration due to small footprint and low power consumption NTP/PTP precise time transfer over Ethernet, including security protocols that prevent network vulnerabilities Low phase noise 10-MHz frequency distribution Configurable pulse signals, including IRIG or HaveQuick timecodes Serial link Time Of Day (ToD) messages Spectracom, spectracom.com GNSS Simulator for advanced research and development The Simceiver by IP Solutions now features Beidou as a simulated signal with access to full parameters rather than the record and playback function used previously. The Simceiver is part of the Replicator system, a multi-frequency, multi-system GNSS simulator for advanced research and development, equipment testing and education. It can also function as a recording, playback and signal analysis instrument. The Replicator is the result of a collaboration with the Japan Aerospace Exploration Agency (JAXA). Besides the Simceiver hardware unit, components include the ReGen control software for real-time simulation, Streamer control software for recording and playback and ARAMIS software receiver for signal analysis. The 24-channel Replicator provides real-time generation of GNSS signals, recording and playback of dual-frequency GNSS RF signals, and GNSS RF signal analysis with JAXA COSMODE ionospheric scintillation monitor. The Replicator offers real-time simulation of dual-frequency GPS, GLONASS, BeiDou or GPS+GLONASS, GPS+BeiDou, GPS+Galileo signals. Comprehensive simulation models include atmosphere, multipath, and more. Also available is signal analysis based on JAXA COSMODE ionospheric scintillation monitor. Two or more units can be used to simulate, record and playback more signals at the same time. Simulated and recorded signals can be stored in digitized format, analyzed by a MATLAB software receiver and played back as RF at any time. Replicator Advantages User defined models with ANSI C API Real-time simulation Record and playback GNSS signal analysis Upgradable to more features , signals and frequencies for the difference in price.

It performs fair-weather tests, but also is designed to subject receivers to suboptimal conditions, extreme situations and combinations of errors difficult to access in real-world tests — all of it finely controlled and indefinitely repeatable. At constellator’s core is software, ensuring that all future constellations, satellites and codes can be handled. Most functional upgrades will then be software-only. Constellator is used in aerospace and defense (among others) for multi-antenna receiver testing for spacecraft launchers, satellite onboard receiver testing (telecom and observation) and defense UAV receiver testing. Constellator includes four spatial reference frames and trajectory editors for ground, marine, aerial and spatial motion and import facility. With hardware-in-the-loop, it receives position updates from test rigs in real time and generates corresponding GNSS signals and messages. Propagation issues can be simulated at individual signal level with different models provided for ionosphere and troposphere. Satellite error modeling options include orbital errors, onboard clock errors, satellite electronics (front-end) defects, satellite dysfunctions and signal fade, disappearance and “evil waveform” incidents.

With industry-standard communication interfaces, the HG4930 is easily integrated into a variety of architectures. The extremely small size, light weight and low power make the HG4930 ideal for most applications. The HG4930 includes MEMS gyroscopes and accelerometers. It employs an internal environmental isolation system to attenuate unwanted inputs commonly encountered in real-world applications. The internal isolation and other proprietary design features ensure the HG4930 is rugged enough to meet the needs of demanding users. The HG4930 is not ITAR controlled. Its Export Control Classification Number (ECCN) is 7A994. Example Applications Aiding a camera pod to track a desired object: For example, a television viewing enhancement systems used in sports broadcasting. Integration with GPS/GNSS to navigate an object from point A to point B: IMU performance is key; errors grow quickly without GPS/GNSS (such as in forested areas, underwater, dense urban). Dynamic antenna platform stabilization: IMU measures small perturbations of a platform under motion (including vibration and shock) and feeds those measurements into a control system that then corrects and stabilizes the platform; without an IMU, communication can be degraded or lost. Robots: Enables robots to navigate indoors with other aiding sources (such as radar or lidar); similar concept to GPS/GNSS aiding.
