IFEN’s SX3 multi-GNSS software receiver tracks all known GNSS signals in view, including Galileo signals, in real time on a standard laptop now and in the foreseeable future (up to 1,000 channels in parallel on a core i7). The included RF front end offers four RF frequency paths with 50-MHz bandwidth each, covering the entire GNSS L-band spectrum. The USB 3.0 interface enables high-speed data transfer with up to 8-bit quantization. An optional dual RF input front end can be used for attitude determination, reflectometry and other applications requiring the synchronized input from two antennas. An optional built-in shock and vibration robust OCXO reference oscillator (MIL-STD 202G) is available, which replaces the standard high-quality TCXO normally used.

The SX3 software lets users configure the data processing, including changing loop bandwidths, integration times and the main processing rate, and choosing between different correlation types. The software includes a multi-correlator providing a two-dimensional (code and Doppler) correlation function visualization in real-time. The receiver comes with several powerful processing algorithms like vector tracking, to improve the tracking of weak signals in degraded environments.

The NEO-M8L Automotive Dead Reckoning (ADR) module by u-blox has integrated motion, direction and elevation sensors. The module integrates gyro and accelerometer with u blox’ GNSS platform M8 to achieve high indoor/outdoor positioning performance for road vehicle and high-accuracy navigation applications.

The module is able to track all visible GNSS satellites including GPS, GLONASS, BeiDou, QZSS and all SBAS, with Galileo to be supported in a future firmware version. Concurrent reception of two GNSS systems is supported. The NEO-M8L module can output a position up to 20 times per second.

In addition to accessing the integrated module’s gyro and accelerometer data, accident reconstruction systems can provide the location of an accident to facilitate insurance claims even if a collision occurs in a tunnel or park house. High-end navigation devices are able to guide drivers through tunnels of several kilometers because of the accuracy of u-blox’ ADR system. Stolen vehicles can be located instantly due to continuous monitoring of sensor data and storage of location in non-volatile memory.

The NovAtel FlexPak6D enclosed GNSS receiver is a flexible dual-antenna solution for application developers seeking a high-precision heading-capable positioning engine for space-constrained applications.

Designed for efficient and rapid integration, the compact receiver tracks Galileo as well as GPS, GLONASS and BeiDou. Antenna placement is flexible: the antenna baseline can be set according to space available on a vehicle and heading accuracy required. The modular OEM6 firmware enables users to configure the receiver for unique application needs. Scalable for sub-meter to centimeter-level positioning, the FlexPak6D delivers NovAtel’s ALIGN precision heading and relative heading firmware, as well as its GLIDE firmware for smooth decimeter-level pass-to-pass accuracy and RAIM for increased GNSS pseudorange integrity.

The GNSS simulator in the vector signal generator R&S SMBV100A is designed for development, verification and production of GNSS chipsets, modules and receivers. The simulator supports all possible scenarios, from simple setups with individual, static satellites up to flexible scenarios generated in real time with up to 24 dynamic Galileo, GPS, GLONASS, BeiDou and QZSS satellites. The simulator also supports Assisted GNSS (A-GNSS) test scenarios, including generation of assistance data for Galileo.

The simulator offers real-time simulation of realistic constellations with up to 24 satellites and unlimited simulation time. Flexible scenario generation includes moving scenarios, dynamic power control and atmospheric modeling. Users can configure realistic user environments, including obscuration and multipath, antenna characteristics and vehicle attitude.

The all-in-one TRIUMPH-LS by JAVAD GNSS combines a high-performance 864-channel GNSS receiver, all-frequency GNSS antenna, and a modern featured handheld. The 864 all-in-view channels include Galileo E1/E5A/E5B, GPS L1/L2/L5, GLONASS L1/L2/L3, QZSS L1/L2/L5, BeiDou B1/B2 and SBAS L1/L5.

The TRIUMPH-LS offers GUIDE data collection, Visual Stake-out (VSO), navigation, six parallel RTK engines, more than 3,000 coordinate conversions, advanced CoGo features, and rich attribute tagging on a high-resolution, bright, 800 x 460 bright display. Two 3-megapixel cameras enable recording of images along with GNSS data.

With VSO, the virtual location of a point to be staked can be seen by a “flag” shown on the Triumph-VS camera image. This visual aid helps users navigate quickly to a point and makes stakeout jobs fast and easy. VSO can be used as a convenient way to get close to a target point before switching to the regular stakeout mode to perform precise measurements.

More than 100 channels are dedicated to continuous interference monitoring. The Triumph-LS monitors and reports interference graphically and numerically with patent-pending interference protection. Interference awareness allows safe GNSS operation in a city, airport and military environment.

The unit can serve as base or rover. It has a GSM modem, UHF transmit and receive, and an internal high-performance geodetic antenna.

The TRIUMPH-LS automatically updates all firmware when connected to a Wi-Fi Internet connection.



GNSS Interference Monitoring Tool

TeleOrbit's GNSS Interference Monitoring Tool

TeleOrbit’s GNSS Interference
Monitoring Tool

TeleOrbit’s software-defined radio receiver and GNSS interference monitoring tool receives and processes all available Galileo signals. Signals that are not yet transmitted and interference sources can be simulated and processed within the software tool.

Within a software-defined radio framework, the analog-to-digital converter is moved as close as possible to the antenna to perform most of the signal processing in software. This leads to adaptable solutions with lower hardware costs that can be easily extended to new signals and systems with only a software update.

The GNSS Software Defined Radio Receiver (GSDR2X) developed by TeleOrbit’s sister company TeleConsult Austria can track most readily available signals from Galileo, GPS and SBAS. By utilizing input from TeleOrbit’s GNSS multi-system performance simulation environment (GIPSIE), even signals not yet transmitted by satellites can be tracked and processed by the GSDR2X. Furthermore, input data can be read from various radio frequency front-ends, either directly or from file.

The modular GSDR2X framework enables new capabilities, such as the GNSS Interference Monitoring Tool (GIMT), which enables the GSDR2X to detect and classify interfering and jamming signals (see figure).
