Jackson Labs Technologies Inc. (JLT) released its tiny, new Micro-Transcoder, a full-constellation, stand-alone, real-time 10-channel GPS simulator. The unit can act as a GPS firewall to identify and block jamming and spoofing attempts, and to provide an alternate PNT source during fully GPS-denied operation.

The one-inch-square Micro-Transcoder module allows glueless retrofitting of existing GPS equipment by upgrading systems with secure and assured positioning, navigation and timing (PNT) capability, the company said. It achieves hardening of the customers’ GPS equipment by splicing the unit in between the existing antenna and the users’ GPS receiver.
It takes the output of any secure PNT source — inertial navigation system (INS), SAASM, M-code, Iridium STL, or concurrent GNSS receiver — and encodes (RF modulates) the baseband PNT and UTC timing information into a standard GPS L1 RF signal.
This RF signal can then be received by any legacy GPS receiver.
The unit is based on JLT’s CLAW GPS simulator and RSR transcoder technologies, and includes a stand-alone full-constellation 10-channels 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 RF signal by simply applying 3.3V power to it.
The Micro-Transcoder can also be operated as a generic high-performance GPS simulator with built-in GPS Disciplined Oscillator, and is supported by a comprehensive free Windows application program 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 PC to be connected to it to function. This makes embedded operation as easy as applying power, and connecting the units’ RF output to the antenna input of any GPS receiver.
By generating a legacy RF GPS signal from any secure PNT source, the Micro-Transcoder allows users to maintain their investment in fielded legacy GPS equipment. Example applications include retrofitting financial transaction time servers with CSAC or rubidium atomic clock holdover capability, and adding GPS RF output capability to concurrent GNSS receivers to allow reception of L1, L2, L3, L5 GPS, GLONASS, Galileo, BeiDou, QZSS, Iridium STL, or any other satellite-based navigation signal to legacy GPS receivers.
It can also be used to add inertial navigation system (INS) capability to vehicles and aircraft.
None of these applications require any modifications to be made to the legacy GPS receiver system; all configurations are done externally using the Micro-Transcoder Windows application or a standard terminal program, and on the assured PNT source.
A real-world customer application is a data-center where communications equipment required a GPS signal to operate. The user wanted to prevent vulnerabilities that an external antenna would have introduced. In this scenario, the Micro-Transcoder provided a fixed-position GPS RF signal to a number of the data centers’ GPS receivers, and allowed the GPS user equipment to operate properly without exposing it to the possibility of external jamming or spoofing.
At 0.97 x 0.97 x 0.4 inches and with less than 0.95W power consumption, the Micro-Transcoder is small enough to be designed into emerging assured PNT products, allowing them to communicate gluelessly to existing legacy GPS infrastructure.

U-blox, a global provider of positioning and wireless communication technologies, is partnering with Arvento Mobile Systems, a Turkey-based fleet telematics company, to develop a compact people and asset tracking device with a long battery life.
The Arvento Treyki Mini has eight operating modes, including special settings for tracking children (with geofencing) and senior citizens (with an integrated fall sensor). It is also suitable for use in sports, racing and asset management. It can also be used as an emergency beacon.
The tracker has an onboard positioning receiver, and reports its location using an internal GSM/GRPS modem. It can operate for up to seven days from its 900mAh LiPo rechargeable battery before it needs to be recharged.

The Treyki Mini relies on the u-blox ZOE-M8Q concurrent multi-GNSS module to discover its location. This system-in-package (SiP) offering is 4.5 x 4.5 x 1.0 millimeters. It provides high accuracy thanks to its ability to receive 72 channels simultaneously, from up to three different GNSS constellations, the company said.
It also offers reliable positioning in challenging environments because it has a sensitivity of –167 dBm and is energy efficient.
Communications for the Treyki Mini are provided by the u-blox SARA-G340 dual-band GSM/GPRS module — its very low standby power of less than 0.90 mA helps extend the Mini’s battery life. The SARA-G340 module also supports firmware-over-the-air (FOTA) updates, enabling Arvento to continue to refine the Treyki Mini after production.
“The Treyki Mini is the result of a very close collaboration between Arvento and u-blox to optimize its size and power consumption,” said Özer Hıncal, general manager, Arvento. “We expect that the strong sense of partnership that evolved between our two companies during the development of the Treyki Mini will lead to further collaboration in the future, especially when it comes to telematics system solutions.”
Septentrio has launched the Mosaic high-precision GNSS receiver module.
Despite its compact size (31 x 31 x 4 millimeters, 1.29 x 1.29 x 0.15 inches), the Mosaic module supports more than 30 signals from all six GNSS constellations, L-band and various satellite-based augmentation systems, the company said.
As a multi-band module tracking all GNSS satellites in view, it is also designed to support future GNSS signals.
It also supports correction services, and uses real-time kinematic (RTK) technology, together with Septentrio’s algorithms, to guarantee maximum accuracy and availability. The surface-mount design of Mosaic is optimized for automated assembly and ease of integration, with a full library of well-documented and flexible interfaces.
“Our new Mosaic module represents the best-in-class option for reliable and scalable position accuracy, with integrity,” said Chris Lowet, product manager at Septentrio. According to Lowet, it provides RTK positioning with a power consumption of 0.6-1 W, and requires no or minimal additional components for the design-in. “These characteristics make it an ideal positioning cornerstone for a variety of mass market UAV, autonomous and robotics applications,” Lowet said.

Robustness to interference. Due to the natural weaknesses of distant GNSS signals and a crowded radio-frequency spectrum, GNSS-based services are vulnerable to unintentional radio-frequency interference (RFI). They are also vulnerable to intentional RFI, attacks intended to disrupt receivers by means of counterfeit GNSS-like signals (known as spoofing), and to intentional transmission of RF energy to mask GNSS signals with noise (known as jamming).
To defend against these threats, Mosaic features Septentrio’s AIM+ technology. AIM+ can suppress the widest variety of interferers, from simple continuous narrowband signals to complex wideband and pulsed jammers, the company added. In addition, the integrated spectrum analyzer allows the RF environment around any Mosaic module to be viewed in real time in both time and frequency domains.
Effective interference countermeasures against threats to GNSS signals also require constant knowledge of the changing RF environment. The Mosaic module helps analyze these threats by continuously and automatically monitoring the GNSS frequency spectrum to detect, characterize, log and mitigate interference events when needed.

Image: Quectel
The module is now sampling to the automotive industry for the development of commercial C-V2X products.
The AG15 C-V2X module is manufactured in accordance to IATF 16949:2016 quality management system standard for the automotive sector, and it fully complies with the automotive product quality processes, including APQP and PPAP.
Pairing with the Quectel automotive-grade LTE module AG35, Quectel’s AG15 is designed to meet the telematics and vehicle-to-everything (V2X) connectivity requirements of the next-generation automotive applications, such as autonomous driving and road safety.
Also known as LTE-V2X, C-V2X is the V2X communication technology based on the globally recognized Third Generation Partnership Project (3GPP) Release 14 specifications. The PC5-based direct communication mode of C-V2X supports vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I) and vehicle-to-pedestrian (V2P) communications on the 5.9-GHz intelligent transport system (ITS) spectrum.
In addition, C-V2X paves a strong evolution path toward 5G new radio (5G NR) and plays an essential part of the future of safe autonomous driving with its capabilities including non-line-of-sight (NLOS) sensing to support high-speed mobility and high vehicular density deployments, the company said.
For positioning function, the AG15 features a built-in multi-constellation high-precision GNSS (GPS/GLONASS/BeiDou/Galileo/QZSS) receiver, with additional support from satellite-based augmentation systems (SBAS) and Qualcomm 3D dead-reckoning technology, which greatly improves the positioning accuracy and speed while simplifying customer designs.
Based on C-V2X technology, the Quectel AG15 module adopts the 3GPP Release 14 C-V2X PC5 protocol. It is designed to allow low-latency, highly reliable and highly dense data exchange between vehicles and their surroundings, enabling effective information sharing among road users in avoidance of collisions, thus improving automotive safety, automated driving and traffic efficiency.
Without the need for a subscriber identity module (SIM), cellular subscription or network assistance, the C-V2X direct communication mode helps reduce complexity and cost for customers.
Additionally, the Qualcomm 9150 C-V2X chipset solution has a built in A7 application processor (1.5 GHz), which could be potentially utilized to run ITS stack and associated C-V2X applications.
“We are very pleased to introduce our first batch of automotive grade C-V2X modules based on the Qualcomm 9150 chipset solution.

The BHI160BP position tracking smart sensor. (Photo: Bosch Sensortec)
Bosch Sensortec has released the BHI160BP, a position tracking smart sensor that uses integrated inertial sensors to improve GPS location tracking.
Bosch will exhibit the new sensor at Electronica Munich, Nov. 13-16.
When used with a GPS or GNSS module, the BHI160BP enables users to take full advantage of pedestrian position tracking with up to 80 percent saving in system power consumption compared with a typical GNSS-only solution, without compromising on accuracy, the company said.
Users benefit from greatly extended battery life and longer charging intervals for wearable applications such as smartwatches and fitness trackers as well as mobile devices such as smartphones.
The new position tracking approach is set to enable a new class of compact devices with even smaller batteries, Bosch claimed.
The BHI160BP tracks a person’s position by intelligently applying an inertial-sensor-based algorithm for pedestrian dead reckoning. To maintain accuracy, it calculates the user’s relative location based on data collected from the inertial sensors and then recalibrates itself every few minutes to obtain the absolute position provided by the GNSS/GPS module. This means that the GNSS/GPS module can be kept in sleep mode for most of the time, which drastically reduces a device’s power consumption and extends its operating time.
“Pedestrian position tracking is a crucial application for mobile applications; unfortunately, GPS modules can rapidly drain a device’s battery capacity — especially when the battery is as small as in wearable devices,” said Stefan Finkbeiner, CEO of Bosch Sensortec. “Our new position tracking smart sensor solves this problem and enables users to navigate reliably while extending the operation of GPS tracking in their devices from several hours up to several days.”
With the BHI160BP, a device can maintain solid accuracy even when the GNSS signal is blocked or weak, such as near tall buildings or indoors, the company added. This ensures accurate pedestrian navigation at all times, even in shielded indoor areas such as subways, Bosch said.
The BHI160BP is a new member of Bosch Sensortec’s BHI160 family and adds application-specific functionality for position tracking. It provides a ready-to-use solution that can be quickly and easily integrated into a system design without requiring an update to a new GNSS module, thereby significantly cutting time to market, Bosch said.
While the current configuration is optimized for use with GNSS receivers (such as GPS), the BHI160BP can also support most of the common global localization technologies. According to the company, the BHI160BP can handle gesture recognition and 3D orientation, with 3D calculations performed by the sensor itself rather than by an application processor.
The new BHI160BP draws 1.3 mA in active operation mode and integrates the company’s Fuser Core microcontroller and a six-axis inertial measurement unit. The BHI160BP offers a variety of customized virtual sensors, such as a calibrated accelerometer, orientation and wake-up gesture, within a single device. It BHI160BP can be extended by connecting additional physical sensors, such as a magnetometer, over a secondary interface.
The new BHI160BP comes in a compact 3 x 3 x 0.95 mm³ LGA-package and is pin-to-pin compatible with the BHI160. It will be available via distribution in December.

The high-frequency nanominiature coax contact is engineered with smaller contacts and a higher RF contact density within a multi-position module. This design enables smaller packaging and saves valuable space, TE said.
Half-size modules can support up to 12 RF contacts, and full-size modules can support 18 contacts or higher, with the option to customize contact count and position.
TE’s NanoRF modules and contacts are versatile, TE said. Their blind-mateable, float-mounted backplane contacts support module-to-module or box-to-box architecture. While they are designed for 0.047-inch coax cable, multiple cable types are available to fit the application’s needs. To bring high-frequency capability into a high-density modular package, the contacts are optimized for signal integrity and support frequencies up to 70 GHz.
The NanoRF’s design features a floating insert on the backplane side, with guide features to pre-align the array of contacts before they engage. This results in reliable mating and consistent RF performance up to 500 mating cycles.
“NanoRF offers outstanding high frequency coax contact density in a rugged modular package, which is ideal for providing reliable RF performance in harsh environments,” said Mike Walmsley, global product manager for TE’s Aerospace, Defense and Marine division. “It has been tested to VITA 72’s high vibration standards and is ready for VPX open architecture under VITA 67.3 — with a roadmap for expansion into other high- density packages.”

Imagination Technologies has introduced a comprehensive GNSS IP offering. The Ensigma Location GNSS IP core supports GPS, GLONASS, Galileo and BeiDou as well as several satellite-based augmentation systems (SBAS) including WAAS and EGNOS.
With Ensigma Location GNSS IP, companies can integrate position, navigation and timing (PNT) services while keeping power consumption to a minimum, the company said.
The Ensigma GNSS IP is designed to be used with a wide range of GNSS receivers.
The IP is optimized for battery-powered remote internet of things (IoT) sensors and edge devices, wearables, health monitors, consumer mobile products, automotive after-sales products such as insurance boxes and road tolling equipment, and asset tracking devices.
A growing number of battery-operated products must support PNT services. Consumers want to track their devices, but don’t want to recharge batteries frequently. In industrial and agricultural environments, users need to track mobile assets to improve efficiency and reduce operational costs, but it isn’t possible to frequently change batteries across numerous devices in disparate locations.
In addition, new regulatory requirements mandate the use of location services in some products, for example, to address spectrum sharing requirements in IoT devices and base stations.
Key features of the Ensigma GNSS IP include:
Ultra-low power operation
Ability to share location information with external wireless technologies such as LTE or Wi-Fi
Options to share peripherals such as memory and system clock to enable reduced total system cost
High sensitivity for indoor location
Support for assistance information using external sources such as LTE and Wi-Fi to improve time to first fix
Radio Frequency Interference (RFI) detection and mitigation
With Ensigma GNSS IP, customers can choose a configuration, from standalone to highly integrated, that works best for their specific system implementation, the company said. The IP can be configured for lowest power or highest integration, and is designed to fit into any existing solution with the optimum level of design and resource reuse.
The Ensigma GNSS IP builds on the Ensigma connectivity engine, which incorporates an ultra-low power CPU core. Imagination employed many innovative GNSS techniques to build on the efficiency of this platform to ensure low-power consumption.
The GNSS IP includes dedicated hardware blocks which enable much lower power compared to a software only solution. In addition, the GNSS IP not only supports continuous fix techniques, but it also supports power-efficient “capture and process” for devices that only require periodic location updates, the company added. This feature further conserves battery life by capturing data, such as fitness information from a wearable device, and storing it for later processing.
The initial solution is optimized for use with SaberTek’s ultra-low power GNSS receiver.
