AUVSI XPONENTIAL is underway in Denver, Colorado, at the Colorado Convention Center. After the first day of touring the XPO Hall of more than 600 exhibits and attending educational sessions lead by industry leaders and speakers, GPS World staff noticed a key theme: mitigating GNSS jamming and spoofing by advancing technology for UAVs.  

Educational Sessions

“Real World GPS/GNSS Protection from Start to Finish,” was presented by Franck Boynton, Vice President of NavTechGPS. He discussed why anti-jam equipment is needed and how to mitigate jamming. Boynton mentioned several anti-jam products, such as NovAtel’s OEM series product line, Septentrio’s AIM+, Tallysman’s HC871SXF and more.

Additionally, GPS World contributing writer, Dana Goward, received a mention for his article regarding the GPS jamming incident on Jan 21, 2022, at Denver International Airport, which can be found here. Boynton also suggested checking out the RNT Foundation, which is a nonprofit, public benefit corporation that helps protect critical infrastructure by promoting resilient navigation and timing, of which Goward is the president and director.

“The Importance of GNSS Security in UAV Applications,” featured a panel of speakers that included Abigail Smith, executive director of UAS security at the FAA, Captain Joe Burns, CEO of the Airo Group and member of the National Space-Based Positioning, Navigation and Timing Advisory Board, Gustavo Lopez, market access manager at Septentrio, Jeff Horne, vice president of security at Skydio, and moderated by Michael Glutting, sales manager at Septentrio. During the panel discussion, the speakers explained types of GPS interference, including jamming and spoofing, and the risk they pose to UAVs. The latest methods for strengthening both GNSS receivers and control units to design secure and robust UAVs was also discussed.

Day-of highlights

Maddie Saines, managing editor, and Jesse Khalil, digital media specialist, had the opportunity to stop by several booths in the XPO Hall on the first day of XPONENTIAL. A few highlights from the day included speaking with Ahmet Salih Erdem, deputy general manager at Tualcom, getting an in-depth look at SBG System’s Qunata Mirco and Ekinox Micro with Yoann Plenet, head of product management, and getting a first-hand look into the newest products from Tallysman Wireless — such as SSL889XF — from Ken MacLeod, product manager for Tallysman.

Percepto has received a waiver from the Federal Aviation Administration (FAA) that allows it to operate unmanned aerial systems (UAS) beyond visual line of sight (BVLOS) in shielded airspace — without humans onsite, and without ground-based or airborne detect and avoid (DAA) systems — for inspection and monitoring operations at critical and non-critical infrastructure sites nationwide.

Under the waiver, low risk “shielded” BVLOS operations are authorized 200 ft above and around assets located on critical infrastructure sites. At non-critical infrastructure sites, shielded BVLOS operations are permitted 50 ft above and around the height of the tallest obstruction located within a half-mile radius of the site.

The operations authorized under this approval build upon recommendations made by the UAS BVLOS Aviation Rulemaking Committee chartered by the FAA. The ARC recognized that shielded airspace near structures and other obstacles where crewed aircraft do not typically operate could be leveraged as a safety mitigation to support safe, scalable, and economically viable UAS BVLOS operations.

The use of Percepto’s UAS to perform critical infrastructure inspections aims to improve worker safety and efficiency of operations by enabling inspections remotely from anywhere in the United States.

Percepto is at XPONENTIAL May 9-11, at booth 3409.

GPS plays a quiet, but integral role in Formula 1 (F1) racing. In a sport where split-second reactions are vital, GPS helps drivers and their teams to improve race to race and navigate tracks safely.

GPS is used to determine the speed of the car, which is beneficial for such things as straight line aerodynamic testing. It also provides data as to how fast F1 cars accelerate, enabling drivers and their teams to predict how much power their competitors are producing on the track.

The streaming of location data can be converted to telemetry, such as what track maps viewers see on F1 broadcasts, that can determine which driver in a head-to-head scenario was faster on each sector of the track. This data is then used to work out strengths and weaknesses of cars relative to each other.

In addition, GPS plays a large role in creating a safe racing space.

If a driver is slowing down to recharge a battery, make space for a hot lap, or cool down tires between runs, and another car is entering the track at full racing speed, this creates safety concerns. GPS receivers on the cars and radio links to transmit their positions are used to show where cars are on the track at any moment. Teams use this information to manage traffic during sessions such as qualifying races to improve overall track safety.

The impact of losing live location data was seen at the 2023 Australian Grand Prix FP1 in late March. At the opening practice session, a red flag was flown due to loss of location data triggered by a glitch in the distribution of live tire information. This caused several near-misses on the track because drivers no longer received traffic advisory calls from their team, reported AutoSport.
