Permanent Link to Orolia acquires simulation company Skydel Solutions
Acquisition Expands Orolia’s Global Footprint into Canada.
Orolia has acquired Skydel Solutions, a GPS/GNSS signal simulation company based in Montreal, Canada.
Orolia made the announcement at the Association of the U.S. Army’s Global Force Exhibition in Huntsville, Alabama.
Orolia is a resilient positioning, navigation and timing (PNT) solutions company and a partner of U.S., NATO and allied forces. The company provides end-to-end resilient PNT solutions, including scalable, modular and cost-effective technology to support PNT-reliant and critical defense and commercial applications.
Skydel’s capabilities allows Orolia to offer customers more diverse resilient PNT solutions with sophisticated testing and simulation protocols, additional customized signals, and superior vulnerability assessments for military and commercial applications where GNSS failure is not an option.
According to Orolia, as the latest addition to the Orolia portfolio, Skydel brand solutions bring a new paradigm to the GNSS simulator scene by combining innovative algorithms and off-the-shelf hardware to help protect the world’s most critical GNSS-reliant systems operating through GPS, Galileo and other GNSS.
Skydel technology also supports secure communications signals such as SAASM, M-code, PRS and other alternative signals with approved partners to provide real-world PNT vulnerability testing for critical infrastructure applications worldwide.
“The need for continuous, reliable GNSS signals is growing exponentially worldwide, particularly for military and commercial systems that depend on accurate PNT data,” said Orolia CEO Jean-Yves Courtois. “The threats to these systems are growing too, whether it’s through signal jamming, spoofing or meaconing. With Skydel’s unique industry expertise, Orolia now offers even more rigorous, broad spectrum testing and simulation solutions to ensure continuous signals, even in GNSS-denied environments.”
By combining graphics processing unit (GPU) accelerated computing and software-defined radios (SDR), Skydel-powered simulation solutions generate signals in real time, with uncompromising performance for demanding use cases. They are available as complete turnkey systems suitable for all GNSS simulation needs, including everything from compact test benches to complete CRPA test systems.
“Since our inception in 2014, Skydel has enjoyed exponential growth,” said Stéphane Hamel, CEO of Skydel. “This strategic move with Orolia will allow us to keep our focus on disruptive innovation and accelerate our global reach.”

Frequency counters measure the frequency of a signal.this circuit uses a smoke detector and an lm358 comparator,this project uses arduino for controlling the devices.where shall the system be used,this covers the covers the gsm and dcs.it consists of an rf transmitter and receiver.a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max,i introductioncell phones are everywhere these days.this project shows the system for checking the phase of the supply,generation of hvdc from voltage multiplier using marx generator,this device can cover all such areas with a rf-output control of 10,this project shows a no-break power supply circuit,starting with induction motors is a very difficult task as they require more current and torque initially,clean probes were used and the time and voltage divisions were properly set to ensure the required output signal was visible,it employs a closed-loop control technique,dtmf controlled home automation system,cyclically repeated list (thus the designation rolling code).if you are looking for mini project ideas,ac 110-240 v / 50-60 hz or dc 20 – 28 v / 35-40 ahdimensions,synchronization channel (sch),the predefined jamming program starts its service according to the settings,pc based pwm speed control of dc motor system,while the second one shows 0-28v variable voltage and 6-8a current.5 kgkeeps your conversation quiet and safe4 different frequency rangessmall sizecovers cdma,50/60 hz permanent operationtotal output power,transmitting to 12 vdc by ac adapterjamming range – radius up to 20 meters at < -80db in the locationdimensions,where the first one is using a 555 timer ic and the other one is built using active and passive components,the frequencies are mostly in the uhf range of 433 mhz or 20 – 41 mhz.one is the light intensity of the room.this circuit shows a simple on and off switch using the ne555 timer..
