GPS integrity module
Seamlessly integrates with existing platforms

The Shift5 GPS integrity module is a platform-agnostic solution for military, aviation, rail, maritime and space applications.
With real-time access and analysis of onboard data, the module assesses changes in navigational position through multi-faceted anomaly detection methods, which alert operators to GPS spoofing attacks as they happen.

Using data collected from onboard systems, the module uses algorithmic position analysis to identify significant position deviations and GPS data validation to verify GPS information accuracy. Discrepancies or deviations that indicate tampering trigger an immediate notification, allowing operators to initiate standard operating procedures (SOPs) rapidly and accurately.

The module is designed for cross-platform deployment, across commercial and military planes, locomotives, vessels and aircraft, as well as on other critical systems such as radar, unmanned aircraft systems (UAS) and weapon guidance systems. It seamlessly integrates with existing platforms and can deploy directly to onboard hardware.

It offers multi-faceted detection and alerts for GPS spoofing attempts, designed to improve the safety and reliability of navigation systems. It uses physics-based spoofing detection to determine whether reported changes in position are physically possible to provide an effective method for initial spoofing detection. The system analyzes data from all sources to detect subtle, sophisticated spoofing attempts, which is essential for identifying more complex spoofing strategies that may evade traditional spoofing detection techniques.

Shift5 alerts can be integrated into existing SOPs to help preempt contamination of other positioning and navigation data, such as inertial navigation calibration against false GPS data. Metadata about the time, location, duration and estimated position of the attack can be passed for inclusion in threat mapping and other geospatial systems for future route avoidance.

The UAV features a high-performance payload, fitted with a 64MP EO/IR camera mounted on a dual-axis gimbal that can support vertical rotation of up to 200°. AIDrone can spot millimeter-sized cracks and detect subtle temperature changes in challenging environments.

AIDrone uses Nearthlab’s vision-based autonomous flight technology to operate autonomously — in zero-light and GPS-denied environments — both indoors and outdoors.

It weighs around 4 lbs and has a foldable structure. AIDrone is designed for intelligence, surveillance, and reconnaissance (ISR) purposes, which makes it ideal for crisis management scenarios such as wildfire response and law enforcement.

ISR UAV
With jamming resistant-radio

The Ghost Dragon intelligence, surveillance, and reconnaissance (ISR) UAV offers higher resistance against jamming and spoofing. The UAV is equipped with a thermal and visual light camera and jamming-resistant radio. Its wide frequency hopping radio is used to provide a jamming-resistant video and telemetry link, which makes it difficult to detect the UAV and interfere with the mission.

The Ghost Dragon ISR uses a dual-band GNSS module that operates on both L1 and L5 bands, which allows for flight operations even in challenging environments. The UAV can operate in radio silence mode in the presence of GNSS and store reconnaissance data on an encrypted SD card to view after the UAV has landed. The video and target location information streamed to the operator is also georeferenced.

The UAV can be redirected, flown back to base, or handed to another operator at a different ground control station at any time.

Juniper Systems, which has more than 30 years of experience in mapping and data collection in a wide variety of applications across industries, recently released a real time-kinematics (RTK) activation for its Geode GNSS receiver that allows mapping accuracy down to a centimeter. Pairing a Geode with the company’s Uinta mapping and data collection software and a Mesa rugged tablet makes it easy for users to share their data — such as the locations of fiberoptic telecommunication lines or of utility manhole covers — with other people working on site or at the office. The Geode and the Mesa meet IP68 protection certification for water and dust ingress; they also have MIL-STD-810G certification against drops, vibration, and extreme temperatures.

In this month’s cover image, the Geode is at the top of the survey pole, the Mesa Rugged Tablet is mounted near the user’s hand, and the screen on the Mesa depicts the Uinta mapping software.

On construction sites, surveying is an ongoing process. Surveyors are the first on the site, before any other work begins, and the last ones there, to map the project “as built.” Total stations with GNSS receivers, as well as tablets and other mobile digital devices are their essential tools, increasingly complemented by unmanned aerial vehicles (UAV) and lidar scanners. Accuracy is their key contribution. In this month’s cover story on GNSS for architecture, engineering, and construction (AEC), we highlight three building projects: a skyscraper in Sweden, a highway in China, and a luxury resort in the Caribbean.

The CWCS method was first used during the construction of the Burj Khalifa and was subsequently applied in the construction of many other high-rise buildings around the world. Swedish surveying company Teodoliten decided to apply this method for the Karlatornet project. Core walls, which are key structural components of high-rises, require a layered construction approach, with multiple concrete pours for each core wall element. CWCS makes it possible to precisely align these core walls with the vertical axis of the building during construction, using GNSS receivers, total stations, inclinometers, and other tools.

When constructing a tall building, it is essential to continuously measure the positions of various elements at its summit to ensure their vertical alignment. This is typically done by placing at the top of the building four GNSS receivers — referred to in this context as active GNSS control points — each with a 360° prism at the bottom. By sighting the prisms and using the 3D coordinates from the GNSS receivers, a surveyor then sets up a total station. This obviates the need for an extensive array of ground control points, which are often not visible from the top, and for holes in the slabs to accommodate vertical laser plummets. Additionally, observations from a nearby reference station are used to post-process the data from the GNSS receivers in post-processed kinematic (PPK) mode to achieve an accuracy of a few millimeters. The Karlatornet project uses four SinoGNSS multi-constellation T300 GNSS receivers for the active control points.

It is also necessary to correct for the movement of the survey platform as the building’s main axis is flexed by the loads applied to it during construction. This is achieved by placing a series of high-precision dual-axis inclinometers along the core walls and then applying a least squares adjustment that takes into consideration the floor height of the measuring devices.

The SinoGNSS T300 receivers operating in GNSS-RTK mode also will be used to monitor and document post-construction building deformations.
