Mayflower Communications Company, a Massachusetts-based leader in advanced anti-jam system solutions for military and commercial markets, has been granted two U.S. patents — US 11,262,457 and US 12,235,365 — that significantly advance its GNSS anti-jam capabilities.
The patents expand Mayflower’s proprietary technology into signals of opportunity (SoOP), enabling interference suppression across both Iridium and GNSS frequency bands.
GPS remains a cornerstone of positioning, navigation and timing (PNT) for both military and commercial platforms. However, its vulnerability to intentional and unintentional jamming and spoofing has underscored the need for more resilient PNT solutions. Signals of opportunity — non-navigational RF signals not originally intended for PNT — can serve as valuable backups when GPS signals are degraded or denied. But like GPS, these signals are also susceptible to interference and require protection to be viable contributors to a resilient PNT framework.
Mayflower’s newly patented technology provides simultaneous protection of GPS and Iridium satellite signals within a compact, low size, weight and power (SWaP) footprint — critical for modern platforms operating in GPS-contested environments.
“The issuance of these seminal patents by the U.S. Patent and Trademark Office affirms Mayflower’s continued leadership in resilient PNT technologies for both military and commercial markets,” said Triveni Upadhyay, president of Mayflower. “Our innovative approach to filtering interference across multiple satellite communication systems — including Iridium — demonstrates our ability to meet the growing demand for GPS-alternative solutions. Leveraging signals of opportunity without significantly increasing SWaP is a key milestone in delivering more robust, operationally viable PNT systems. We’re excited to bring this technology to our partners across sectors.”
Taoglas has expanded of its Comet Series with the MA58x family of compact, discrete, screw- or through-hole mount puck antennas.
Metal structures or flat surfaces, such as cabinets, can affect antenna performance and change the electrical groundplane. The Comet MA58x series is specifically engineered to maintain stable, high-efficiency operation in these challenging conditions.
Conventional LTE antennas rely on their RF cable to achieve low-band efficiency, particularly when the cable itself is routed inside a metal enclosure, turning it into an unintended radiator. The MA58x design removes this dependency, enabling efficient radiation and delivering at least 20% better performance than comparable alternatives.
With a footprint of 101 x 101 mm and low profile of 20 mm, the antennas deliver reliable multi-antenna connectivity across GNSS constellations including GPS, GLONASS, Galileo, and BeiDou, as well as 5G/4G MIMO and Wi-Fi 6/7. Advanced RF design enables consistent gain and efficiency across global cellular frequencies from 600 MHz to 6 GHz and Wi-Fi bands up to 7.125 GHz, while also supporting legacy 2.4/5.8 GHz Wi-Fi and Bluetooth for maximum compatibility. These levels of performance are rarely achieved in antennas of this size, and even more so when installed on metallic structures.
The rugged, weather-resistant housing is molded in Acrylonitrile Styrene Acrylate (ASA) for long-term outdoor durability, and the IP67-rated enclosure with a screw/stud mount provides a permanent installation option that ensures secure, reliable operation in vibration-prone and harsh conditions such as fleet vehicles, heavy equipment, and industrial automation.
The new antennas are available in multiple configurations and in either black or white enclosures. Custom cable lengths and connector options are also offered, making integration more flexible for OEMs and system designers. The MA58x series is suited to gateways and routers, public safety systems, point-of-sale terminals, digital signage, smart home automation, robotics and industrial automation. The Comet Series also offers a magnetic mount MA32x variant to address different deployment needs.
Further details on the design principles that deliver these performance gains are available in a Taoglas white paper.
Telit Cinterion, an end-to-end IoT solutions enabler based in Irvine, California, has launched the SE869eK5-DR, a dual-band, multi-constellation positioning receiver with untethered dead reckoning (UDR) built on the Airoha AG3335 chipset family.
The UDR ensures reliable, continuous positioning even when satellite signals are lost due to jamming, interference or physical obstructions, delivering continuous and reliable location data for mission-critical applications without depending on a car connection.
With its power-efficient design, the module is ideal for mission-critical applications in business and government that demand ultra-reliable location information, and long battery life. Applications include fleet management, automotive telematics systems, and high-value asset tracking, where uninterrupted and precise location data is critical for operational efficiency.
Building on the successful Telit Cinterion SL869 series, the SE869eK5-DR adds an integrated six-axis sensor for UDR. This allows the module to maintain a position fix even when signals are blocked or jammed, able to track high-value assets deep inside buildings or in underground parking garages.
The SE869eK5-DR also supports L1 and L5 bands, which maximizes resiliency through frequency redundancy. If one band’s signals are degraded by physical obstructions, the other band provides an alternative set of signals. The module also supports differential GNSS (DGNSS) positioning for applications that require sub-meter-level accuracy.
The SE869eK5-DR includes features that streamline product development. Its UDR technology is simple to integrate because it doesn’t require any external application information, which shortens the design phase. It also automatically identifies the direction of movement (forward or reverse), eliminating the need for a separate heading pin. While the SE869eK5-DR introduces an additional 34 pins for future use, it remains backward compatible with previous 24-pin generations, allowing device OEMs to upgrade existing designs.
SE869eK5-DR engineering validation testing (EVT) samples are available now, with design validation testing (DVT) samples scheduled for November.

Advanced Navigation said the Boreas D90 FOG INS represents the type of technology that will be developed and manufactured at these new facilities.
Aerospace and defense applications depend on position, navigation and timing (PNT) technology for mission-critical accuracy and reliability. But integrating PNT into designs requires extensive specialized knowledge.
To accelerate development, Microchip Technology has introduced a portfolio of GNSS Disciplined Oscillator (GNSSDO) modules that integrate the company’s atomic clock and oscillator technologies, including the Chip-Scale Atomic Clock, Miniature Atomic Clock and Oven-Controlled Quartz Crystal Oscillators.
The GNSSDO modules process reference signals from GNSS or alternative clock sources and discipline onboard oscillators to reference signals, enabling precise timing, stability and holdover performance based on application requirements. The modules serve military and defense applications including radar, satellite communications, mounted and dismounted radios, vehicle platforms and other critical PNT applications, including GNSS-denied environments.
A GNSSDO module functions as a PNT subsystem within larger system designs or as a standalone system, providing precise timing critical to high-performance systems. Microchip engineers and manufactures the local oscillators used in the modules. Other Microchip components include 32-bit microcontrollers and SmartFusion 2 field-programmable gate arrays.
MD-013 ULTRA CLEAN: Microchip’s highest-performance standard GNSSDO module supports multiple GNSS constellations or external reference input. The module uses a high-performance OCXO that enables outputs with ultra-low phase noise and short-term frequency stability. Phase noise performance specifications are minus 119 dBc/Hz at 1 Hz offset and noise floor of minus 165 dBc/Hz. Short-term frequency stability, measured by Allan Deviation, is 3E-13 at 1-second tau, 6E-13 at 10-second tau and 9E-13 at 100-second tau. The module generates 1 PPS TTL, 10 MHz sine wave and 10 MHz square wave outputs disciplined to an embedded 72-channel single-band GNSS receiver, with optional upgrade to configurable L1/L2 or L1/L5 dual-band, multi-GNSS receiver.
MD-300: Designed for harsh environments in a 1.5 in-by-2.5-in footprint, the MD-300 features an embedded MEMS OCXO or TCXO as the local oscillator, enabling low g-sensitivity, high shock and vibration tolerance and low thermal transient response. Its size, weight, and power performance make it suitable for applicationssuch as drones and manpacks.

Software can configure various parameters, including inputs, outputs, auto switching, holdover parameters, GNSS tracking and observables, and reporting messages from the serial interface.
Advanced Navigation has released the Boreas 50 series, marking the company’s smallest fiber-optic gyroscope (FOG) inertial navigation system (INS).
The new product line consists of two devices, the A50 attitude and heading reference system and the D50 strategic-grade INS. Both units feature north-seeking gyrocompasses designed to determine true north without relying on GPS signals or magnetic references.
The 50 series weighs 910 g and incorporates Advanced Navigation’s sensor fusion technology, which processes data from multiple sensors to maintain accuracy during GPS outages or interference. The system can detect Earth’s rotation to establish directional orientation within minutes of activation.
An optional Electronic Counter-Countermeasure capability is available for the D50, designed to detect and counter GPS jamming and spoofing attempts. The feature targets operations in contested electromagnetic environments where adversaries may attempt to disrupt satellite-based navigation.
“The modern battlefield is no longer defined by only physical boundaries, but by electromagnetic dominance,” said Maximilian Doemling, head of product at Advanced Navigation. “Assuming navigation will ‘just work’ is a mission-critical oversight.”
Performance Specifications
The system achieves heading accuracy of 0.5° secant latitude through gyrocompassing, with roll and pitch accuracy of 0.03°. Positional accuracy reaches 0.01 m circular error probable at 50% confidence level when GPS is available.
The devices meet military standards for shock and vibration testing, addressing requirements for platforms operating in harsh environments. The compact form factor enables integration into space and weight-constrained systems.
Defense applications for the 50 series span multiple domains. Military pointing platforms, including radar systems, can use the technology for target tracking and identification while mobile or stationary. The system’s rapid stabilization capabilities support accurate targeting despite motion and environmental interference.

Counter-unmanned aircraft system platforms benefit from the precise heading and stabilization features when tracking aerial threats. The north-seeking gyrocompass enables rapid target acquisition and tracking in dynamic operational environments.
Maritime vessels operating under GPS-denied conditions can maintain navigation capabilities and threat identification through the system’s independent positioning features. The technology aims to preserve tactical advantages when satellite signals are unavailable.
Intelligence, surveillance and reconnaissance platforms, along with unmanned aircraft systems, can address navigation failures and targeting errors caused by electronic warfare and sensor drift. The compact design accommodates both new and legacy aircraft integration requirements.
Ground vehicles, whether autonomous or crewed, gain protection against electronic interference that could compromise navigation and situational awareness. The anti-jamming and anti-spoofing capabilities maintain consistent positioning data during operations.
Advanced Navigation‘s defense division consists of military veterans who collaborate with system integrators, program offices and end-users to develop tailored solutions. The company plans to double its defense team size within the year.
The firm’s vertically integrated manufacturing approach aims to reduce production lead times compared to industry standards. Products carry a three-year warranty, and the 50 series provides a direct upgrade path for users of the company’s existing Spatial FOG Dual system.
The technology represents ongoing development in assured positioning, navigation and timing systems as military operations increasingly face electronic warfare threats targeting GPS-dependent systems.
