CAST Navigation CAST-SGX GPS Satellite Simulator The new 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 x 11 x 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 and portable, operates on AC or battery power, and features 16 channels of L1 C/A and P codes. Based on CAST’s technology that has been developed for use in the company’s larger military products, it is extremely accurate and repeatable. 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 Plus 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. The user can select from a variety of vehicle types and simulate static or dynamic motion. The user may also employ antenna gain patterns and vehicle silhouettes if desired. The user may generate a trajectory by defining a total mission profile using a six-degree-of-freedom model. The new scenarios can be downloaded via USB port or SD card interfaces. CAST has been in the GPS simulation and support business for more than 30 years, designing, developing, manufacturing, and integrating innovative GPS/INS simulators and associated equipment for government, military, prime vendor, and consumer markets. www.castnav.com phone: 978 858-0130 email: sales@castnav.com IFEN Inc.

With its small size and all-in-one design, LabSat 3 makes it easier than ever to collect raw satellite data in the same environment that end users experience in everyday use. This enables repeatable and realistic testing to be carried out under controlled conditions. LabSat 3 doesn’t need to be connected to a PC to record live-sky GNSS signals. With one-touch recording to SD card and a two-hour battery life, it can be used in any outdoor location to create real-world scenarios, for eventual replay back in the lab. As well as recording GPS, GLONASS, BeiDou, QZSS, Galileo, and SBAS signals, it can simultaneously log CAN bus, serial, or digital data, embedded alongside the satellite information. This additional information can then be replayed alongside the GNSS output, with synchronization to within 60 ns. A 1 PPS signal can also be generated using the internal GPS receiver. LabSat 3 can be used as a replay system out of the box with a set of pre-recorded scenarios supplied as part of the package, recorded from various locations around the globe. SatGen software, a free version of which is included with LabSat 3, allows for scenario generation of user-defined trajectories, with precise control over velocity, heading, height, and constellation profiles. Routes are also easily created in Google Maps, and the software also supports NMEA and KML file import. SatGen gives the test engineer the ability to develop a product using simulations that would be difficult or impossible to record due to geographic location or safety constraints. LabSat 3 is available in four variants: replay only, or record and replay, of a single channel — one of GPS/Galileo/SBAS/QZSS, GLONASS, or BeiDou; and replay only, or record and replay, of dual channels — two of GPS/Galileo/SBAS/QZSS, GLONASS, or BeiDou. LabSat is currently used by many leading manufacturers of GPS chipsets, portable navigation devices, smartphones, and by major car companies in their test, development, and production processes. www.labsat.co.uk; phone: +44 (0)1280 823803 Rohde & Schwarz R&S SMBV100A: GNSS Simulator on Vector Signal Generator Rohde & Schwarz extends the functionality of the R&S SMBV100A vector signal generator by adding BeiDou/Compass capability to its integrated GNSS simulator.
