Calls made by 24 satellites running Global Positioning System (GPS) services are more expensive than calls to help you find the nearest gas station. From ground missions to missile systems, the military depends on GPS. The military’s dependence on GPS is so high that its personnel and agencies have warned that GPS may become a single point of failure. If the system fails, the military will regularly organize exercises without using the system. Global civilian life depends on GPS more than we know.
Although these 24 satellites may fail for various technical reasons, they are also worried that opponents using jamming technology will prevent access to GPS. This attack will have an impact on the critical applications of civil infrastructure (GPS-based power networks and ATM networks) and will greatly disrupt military operations.
In recent years, a team in the aeronautical communications system implementation department has developed Blind Interference Signal Suppression (BLISS) technology, designed to eliminate potential interfering signals—GPS jammers.
Because the GPS signal on the earth is very weak, GPS signals received by ground users are easily blocked. On the battlefield, the enemy can intentionally block the GPS to prevent the soldiers from knowing their exact location. In Canada, there are many documented cases that use gps jammer purchased on the Internet to reject location information. Specifically, man-made jammers are easy to obtain, although they are illegal, and have been used to circumvent GPS tracking technology.
Dr. Philip Dafesh said: “BLISS uses a set of proprietary algorithms to estimate the specific characteristics of high-power jammers, so as to mitigate the impact of various powerful jammers.” BLISS can be implemented with existing receivers as an independent device between the GPS receiver and its antenna, or it can be integrated into future receiver chipsets.
BLISS is effective for many types of interference
There are well-known techniques for eliminating interference, which focus on eliminating interference in a narrow band in a small frequency range. When the GPS jammer frequency changes rapidly, these techniques will fail. Unlike these traditional technologies, BLISS can also effectively combat interference that matches the target signal, and is not sensitive to interference that rapidly changes frequency or phase characteristics.

This technology is very promising and has been licensed by Talen-X, a subsidiary of Orolia, which specializes in the production of precise time and frequency products for solving global navigation satellite system problems.
The research and development of BLISS was originally funded by the Aerospace Innovation Laboratory (iLab), which was designed to encourage engineers to explore innovative solutions to solve space capacity problems. BLISS is an example of how the ideas generated in iLab can be turned into real solutions.
Dr. Esteban Valles, Head of Implementation, said: “We have a very talented and diverse group of employees who use cutting-edge technology from many fields to create and deliver operational proof-of-concept devices, such as BLISS. The concept of communication.
