The D70 is the latest release in the Boreas digital FOG (DFOG) series, offering a new performance grade with superior accuracy, exceptional stability and reliability. The technology is suited to surveying, mapping and navigation across subsea, marine, land and air applications.
“We are thrilled to expand the Boreas series with the D70. It’s a system that will provide additional flexibility in the Boreas family, making ultra-high accuracy inertial navigation far more affordable than with previous FOG INS systems,” said Xavier Orr, CEO and co-founder of Advanced Navigation. “This patented technology opens the possibility for adopting FOG INS systems across a much broader range of vehicular applications, particularly autonomous vehicles and aircraft where weight and size are at a premium.”
Boreas D70 combines closed-loop DFOG and accelerometer technologies with a dual-antenna real-time kinematic (RTK) GNSS receiver. These are coupled with Advanced Navigation’s artificial-intelligence-based fusion algorithm to deliver accurate and precise navigation.
The system features ultra-fast gyrocompassing, acquiring and maintaining an accurate heading under demanding conditions. While the D70 does contain a GNSS receiver, it is not required for gyrocompass operation.
Based on the company’s DFOG technology, the D70 delivers a 40% reduction in size, weight, power and cost (SWaP-C) when compared to systems of similar performance.
0.01° roll and pitch
0.1° secant latitude heading (gyrocompass)
0.01°/hour bias instability
10 mm position accuracy
The Boreas Series
The Boreas DFOG series features ultra-fast gyrocompassing and can acquire heading, either stationary or dynamically, in less than two minutes. The gyrocompassing allows the system to determine a highly accurate heading without any reliance on magnetic heading or GNSS.
The technology stems from Advanced Navigation’s artificial intelligence sensor-fusion algorithm allowing the system to extract significantly more information from the data. It is designed for control applications, with a high level of health monitoring and instability prevention to ensure stable and reliable data.
Advanced Navigation designed Boreas from the ground up for reliability and availability. The hardware and software are designed and tested to international safety standards and have been environmentally tested to MIL-STD-810. The system achieves a mean time between failure (MTBF) of more than 70,000 hours.
Additional features of the Boreas D70 include Ethernet, CAN and NMEA protocols, as well as disciplined timing via a PTP server and 1 PPS. An embedded web interface provides full access to all of the device’s internal functions and data. Internal storage allows for up to 1 year of data logging.
About DFOG Technology
DFOG is patented technology, which has been developed over 25 years involving two research institutions. DFOG was created to meet the demand for smaller and more cost-effective FOGs, while increasing reliability and accuracy.
The first generation of FOG, made available in 1976, used analog signals and analog-signal processing. The second generation was developed in 1994 and is still used to this day. It improved upon the first generation with a hybrid approach using an analog signal in the coil with digital signal processing.
In 2021, FOG evolved into DFOG. This third generation of FOG sets itself apart by being completely digital, providing higher performance and reliability while enabling a 40% reduction in SWaP-C.
To achieve this, three different yet complementary technologies have been developed to improve the capabilities of FOG.
Digital Modulation Techniques. DFOG uses a specially developed digital modulation technique passing spread spectrum signals through the coil. The new digital modulation technique introduced in DFOG technology allows in-run variable errors in the coil to be measured and removed from the measurements. This makes DFOG significantly more stable and reliable than traditional FOGs. It also allows a smaller FOG with less coil length to achieve the accuracy of one with a longer coil.
Revolutionary Optical Chip. By integrating five sensitive components into a single chip and removing all the fiber splices, the size, weight and power are reduced considerably while significantly improving reliability and performance.
Specially Designed Optical Coil. DFOG employs a specially designed closed-loop optical coil, developed to take full advantage of the digital modulation techniques. The design allows for optimum sensing of in-run variable coil errors using the new digital modulation technique. It also provides a very high level of protection for the optical components from shock and vibration.
Lantronix Inc. has launched its new PNT Series GNSS receiver modules. The embedded modules provide an easy-to-use, cost-effective solution to enable the addition of GNSS functionality to products, Lantronix said, supporting the internet of things (IoT).
The new PNT Series modules are suitable for use in consumer solutions including people, pet and asset tracking devices, as well as agriculture asset monitoring and commercial solutions such as drones, toll-road charging, fleet management, maritime, rail, critical infrastructure and utilities.
“With the addition of the GNSS receiver modules, Lantronix is expanding its embedded IoT family to meet the growing demand for GNSS capabilities in a wide range of essential, often critical, consumer and commercial applications,” said Brian Jaroszewski, lead product line manager at Lantronix. “Adding positioning and tracking, navigation and timing capabilities supports essential processes in many industries, empowering our customers to propel our world forward with enhanced safety, security and the increased ability to more effectively and remotely manage people, places and things.”
According to the European Union Agency for the Space Program (EUSPA), by 2031 more than 10 billion GNSS devices will be in use across the world. Mass-market segments — consumer solutions, tourism and health — will contribute to 92 percent of all devices in use. The global GNSS downstream market revenues, covering both device sales and service-related revenues, is expected to grow at a CAGR of 9.2 percent over the next decade, reaching a total of USD $486 billion by 2031.
