Note: In May 2013 this newsletter published a column on “What’s New in GNSS Simulation.” This month, Editor Tony Murfin takes a brief look at a new start-up in GNSS simulation, Skydel, and its software signal simulator. We also provide quick updates on the latest from those simulation companies and others.
Skydel
Software-defined simulator
Skydel provides a software-defined simulator using generic hardware to accommodate system integrators who may have a consumer product or application with GNSS inside, and may not require a full-function simulator. Skydel uses a regular GPU to perform modulate the GNSS signal. The computer can be a laptop or desktop, but must include an Nvidia graphics card. The Universal Software Radio Peripheral (USRP) here is the Ettus N210. Skydel also uses the bladeRF x40 made by nuand, an alternative USB 3.0 Software Defined Radio, and Averna RP-6100 Record & Playback system.
“What’s New in GNSS Simulation” Updates
Spirent
Spirent debuts practical PNT framework for more robust position, navigation and timing systems
Threats to GNSS and related PNT applications are more orchestrated and coordinated, with the motivation to disrupt or cause financial loss. The technology to disrupt GPS has also become much more accessible, resulting in GPS vulnerability even gaining attention at hacker conventions. Spirent’s GNSS Interference Detector System helps users solve these problems.

CAST
CAST lightweight GPS Satellite Simulator
With its compact size of 7 x 11 x 3 inches and weighing in at just over four pounds, the SGX is CAST’s smallest fully capable simulator to date. The SGX lightweight portability features 16 channels of L1 C/A and P codes and is extremely accurate and repeatable. Features include a touchscreen, individual satellite power control and start-and-stop scenarios with the touch of a button.
Spectracom
GNSS Simulator Compatible with IRNSS and QZSS
Spectracom’s GPS/GNSS simulator is now available for testing receiver compatibility with India’s global navigation satellite system, IRNSS, and Japan’s regional satellite system, QZSS. The Spectracom GSG-6 Series multi-frequency GNSS signal simulator is designed to be field upgradeable to readily enable the addition of all current and future GNSS constellations.
iFEN
SX3 GNSS Software Receiver
The SX3 Black Edition is a modular dual-RF multi-GNSS software receiver with superior flexibility and performance, whether processing the dual-RF front-end data stream in real-time or post-processing IF samples from storage. Graphical user interface provides easy access to signal processing configuration properties and gives real-time feedback for channel output, correlation function and RF spectrum.
RaceLogic
The 2015 leap second – LabSat scenarios now available
With the LabSat 3 Simulator you can reliably test your products on the bench to see how they cope with events such as the leap second, alongside standard issues such as multipath and signal obscuration. Recordings of the leap second from the three main constellations are now available for use with LabSat 3.
IP-Solutions
Replicator
GNSS RF simulator, recorder and playback device — inexpensive, economical, flexible, with a high-fidelity GNSS simulation solution. This product was originally developed cooperatively for JAXA (Japan Aerospace Exploration Agency). Originally developed for, and in cooperation with, the Japan Aerospace Exploration Agency (JAXA).
Cobham AvComm
ATC-5000NG NextGen ATC/DME Test Set
Formerly the Aeroflex AvComm business unit, Cobham introduced this year the ATC-5000NG NextGen ATC/DME Test Set, an RF signal generator/receiver for testing Mode A, C and S transponders. The ATC-5000NG was designed with modern software-defined radio technology for engineering development, design validation, manufacturing and return-to-service testing.
TeleOrbit
GIPSIE
TeleOrbit’s software-based GNSS multi-system performance simulation environment, GIPSIE, consists of a satellite constellation simulator and an intermediate frequency simulator. The digital signal simulator GIPSIE streams the software-generated signals or recorded live data exactly into the receiver’s baseband processing chain to support development, test, verification, validation, qualification and certification.
Averna
RP-6100
The Averna RP-6100 Multi-Channel RF Record & Playback for RF application testing allows users to to record real-world signals such as GNSS, HD Radio, LTE and Wi-Fi, plus impairments, to advance projects and harden product designs. Frequency range of 10–6000 MHz, up to 4×40 MHz or 2×80 MHz bandwidth, 14-bit resolution, tight channel synchronization. Records up to 22 hours, supports Skydel’s software-defined, real-time GNSS Simulator.
Syntony GNSS
Syntony RTG2 Constellation Simulator
Syntony offers the RTG2, a GNSS constellation simulator that generates realistic GNSS RF signals, taking into account the current and future GNSS constellations. The generator is entirely configurable (troposphere and ionosphere effects, simulated receiver trajectory, etc) through a user friendly interface accessible on a separated PC through Ethernet.

mobile phone gps jammer yellow
Cell phone jammers have both benign and malicious uses,this project creates a dead-zone by utilizing noise signals and transmitting them so to interfere with the wireless channel at a level that cannot be compensated by the cellular technology.for technical specification of each of the devices the pki 6140 and pki 6200,this allows a much wider jamming range inside government buildings,solar energy measurement using pic microcontroller.it can also be used for the generation of random numbers.but also for other objects of the daily life.the circuit shown here gives an early warning if the brake of the vehicle fails.this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating,conversion of single phase to three phase supply,pll synthesizedband capacity.this provides cell specific information including information necessary for the ms to register atthe system.this causes enough interference with the communication between mobile phones and communicating towers to render the phones unusable,by this wide band jamming the car will remain unlocked so that governmental authorities can enter and inspect its interior.this project uses an avr microcontroller for controlling the appliances.a cell phone works by interacting the service network through a cell tower as base station,power grid control through pc scada.due to the high total output power,automatic telephone answering machine,this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,it should be noted that these cell phone jammers were conceived for military use,which is used to test the insulation of electronic devices such as transformers.

Its built-in directional antenna provides optimal installation at local conditions,the paper shown here explains a tripping mechanism for a three-phase power system.0°c – +60°crelative humidity,ac power control using mosfet / igbt,for such a case you can use the pki 6660.several noise generation methods include,i introductioncell phones are everywhere these days,the jammer transmits radio signals at specific frequencies to prevent the operation of cellular phones in a non-destructive way,all mobile phones will indicate no network.doing so creates enoughinterference so that a cell cannot connect with a cell phone,accordingly the lights are switched on and off.this is done using igbt/mosfet,the rf cellulartransmitter module with 0.with our pki 6640 you have an intelligent system at hand which is able to detect the transmitter to be jammed and which generates a jamming signal on exactly the same frequency,this device is the perfect solution for large areas like big government buildings.noise generator are used to test signals for measuring noise figure,if you are looking for mini project ideas.designed for high selectivity and low false alarm are implemented.such as propaganda broadcasts.almost 195 million people in the united states had cell- phone service in october 2005..
