Synchronization for RSG/Real Time/HIL Usage Tech Note
This technical note gives information about GSG-6 synchronization consideration for RSG/REAL TIME/ HIL usage on GSG-5 and 6 units, especially when integrating your system with OPT- RSG option installed on your simulator unit.
Sensor Simulation with GPS Testing
GPS simulators are able to test the integration of a GPS/GNSS receiver into a nav system by generating signals corresponding to virtually any condition including vehicle dynamics. They can also generate signals for other sensors for a comprehensive system test. As the simulator generates satellite data for a given trajectory, it simultaneously calculates position and attitude data in six degrees of freedom in real-time; forward/backward, left/right and up/down as well as the rotations about three perpendicular axes, pitch, yaw, and roll; which can be queried and used in integrated test systems.
Frequency Measurements in MDA Mode for HP53310A Users
The TimeView 3 software is intended to make measurements easy for the current user of the HP 53310A Modulation Domain Analyzer. The added MDA mode is designed to emulate the parameters of the HP 53310A making the transition to the TimeView 3 solution seamless
Leap Second Testing Made Easy
Spectracom’s GNSS constellation simulators can easily simulate a leap second event such December 31, 2016. A typical test can take as little as 30 to 35 minutes to set up and run. A sample leap second scenario is available for download. This application note provides background on the leap second event and describes leap second testing with the Spectracom simulator.
Programming Interfaces for Automation and Remote Control for GSG Series Simulators
One of the benefits of Orolia GSG Series GPS/GNSS simulators is that it does not require any external controller and can operate for 31 days continuously (longer if the unit is connected to the internet). However, there are many situations where remote control from an external program is helpful and required when integrating GPS signals with other test parameters. GSG simulators can be connected to a PC using Ethernet, GPIB or USB. A SCPI command set allows for remote control and integration into test systems.
Testing SAASM and Carrier Phase Receivers
Orolia’s GSG-6 GPS/GNSS simulators can be configured for dual frequency L1/L2 simulation. It generates both the C/A and P code signals simultaneously for the GPS and GLONASS navigation systems. Though it does not have an encryption capability to simulate a true classified P(Y) signal, it is still a powerful tool for acceptance testing of classified Selective Availability / Anti-Spoofing Module (SAASM) receivers. This technical note explains how to use the simulator for military SAASM receiver testing and for also testing commercial carrier phase receivers that use the L2 P(Y) signal.
Vehicle Modeling with GPS Simulation Testing
The typical application for a GPS simulator assumes an unobstructed view of the satellites. For advanced testing applications, it is possible to model the placement of the GPS antenna relative to the vehicle body. Starting in application software version 6.2 of the GSG series GPS simulators, vehicle modeling allows the simulated satellite signals to be blocked by the vehicle. Applications of this feature include aircraft maneuvers.
Environmental Modeling with GPS/GNSS Simulators
The value of a GPS simulator is to generate RF signals corresponding to real-world scenarios for comprehensive testing from the bench. In addition to features such as multi-path and interference conditions, Orolia’s GSG series GPS/GNSS simulators can simulate signal obscuration via Environmental Models starting in application software version 6.1.
Using an Antenna with GSG 5/6 Simulators
When using the GSG signal generator with an optional antenna, one must consider additional regulations controlling the radiation of GPS-like signals into the air.
