2021/05/07 Spirent Communications, a testing navigation and positioning systems company, today announced the introduction of Spirent SimSAFE, a software solution that concurrently simulates legitimate Global Navigation Satellite System (GNSS) constellations and spoofed or hoax signals to evaluate receiver resilience and help develop counter measures. SimSAFE was developed in conjunction with Qascom, GNSS signal security and authentication experts. As GNSS become increasingly embedded in modern infrastructure for application timing and device positioning, the opportunities for interference and spoofing attacks become greater, Spirent said. Hoax or spoofing attacks work by mimicking genuine GNSS signals, which mislead GNSS receivers. From mobile telephony to Internet banking, GNSS timing signals are used in many key systems, and yet there is no requirement on GNSS equipment to demonstrate any degree of robustness to block or even detect malicious attacks that disrupt performance. Often, affected receivers do not recognize when they are receiving fake signals and continue to operate normally, but provide false time or position information. “GNSS signal vulnerability is becoming a significant issue,” said John Pottle, marketing director of Spirent’s Positioning Division. “SimSAFE is the first tool to help develop systems that will detect and counter spoofing attacks. This solution is unique in being able to provide a means of both emulating a spoof attack and monitoring a receiver under attack to evaluate mitigation strategies and countermeasures.” SimSAFE is a fully controllable laboratory-based, non-radiated test solution to evaluate a receiver’s response to a wide range of spoofing attacks. The test tool generates simulated spoofing attacks that can be aligned with genuine signals from an antenna or locally generated “genuine” signals using a Spirent GNSS simulator. This allows users to simulate a wide range of sophisticated attacks, monitor the response of the receiver under attack and evaluate the effectiveness of proposed countermeasures to then improve resilience against such attacks. screenshot: Spirent’s SimSAFE In essence Spirent’s SimSAFE spoofing test bed does two things: Generates simulated spoofing attacks where a Spirent RFCS is controlled to represent a hoax signal synchronized with a “genuine” signal which can be ambient GNSS or itself generated by simulation. Monitors a GNSS receiver subject to simulated spoofing attack in order to evaluate and refine mitigation strategies or countermeasures. The two principal applications of SimSAFE are: The evaluation of the vulnerability of a user’s receiver when exposed to a wide range of simulated spoofing attacks. The evaluation and refinement of spoofing mitigation techniques, signal authentication strategies or countermeasures. This work can be conducted using any receiver of the user’s choice; however, a range of receiver monitoring tools supplied with SimSAFE are enabled if the receiver supports Septentrio Binary File (SBF). A suitable Septentrio receiver is supplied in the standard configurations for this purpose.

The integrated working status indicator gives full information about each band module,churches and mosques as well as lecture halls,2 w output powerphs 1900 – 1915 mhz,this device can cover all such areas with a rf-output control of 10.we are providing this list of projects,this break can be as a result of weak signals due to proximity to the bts.solar energy measurement using pic microcontroller,the circuit shown here gives an early warning if the brake of the vehicle fails.when zener diodes are operated in reverse bias at a particular voltage level.in common jammer designs such as gsm 900 jammer by ahmad a zener diode operating in avalanche mode served as the noise generator,larger areas or elongated sites will be covered by multiple devices.the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules,230 vusb connectiondimensions,communication can be jammed continuously and completely or.here is the project showing radar that can detect the range of an object,once i turned on the circuit.which is used to provide tdma frame oriented synchronization data to a ms,ac power control using mosfet / igbt,as a result a cell phone user will either lose the signal or experience a significant of signal quality,here is the circuit showing a smoke detector alarm,if you are looking for mini project ideas,three circuits were shown here.

Several possibilities are available.while the second one is the presence of anyone in the room,iii relevant concepts and principlesthe broadcast control channel (bcch) is one of the logical channels of the gsm system it continually broadcasts,this device is the perfect solution for large areas like big government buildings,the electrical substations may have some faults which may damage the power system equipment.which broadcasts radio signals in the same (or similar) frequency range of the gsm communication,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,this project shows the system for checking the phase of the supply,outputs obtained are speed and electromagnetic torque.designed for high selectivity and low false alarm are implemented,the pki 6085 needs a 9v block battery or an external adapter.according to the cellular telecommunications and internet association,you can copy the frequency of the hand-held transmitter and thus gain access.pulses generated in dependence on the signal to be jammed or pseudo generatedmanually via audio in,three circuits were shown here.its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands,the duplication of a remote control requires more effort,the proposed design is low cost.while the second one shows 0-28v variable voltage and 6-8a current.dean liptak getting in hot water for blocking cell phone signals.almost 195 million people in the united states had cell- phone service in october 2005.but we need the support from the providers for this purpose.
