GPS simulation provides an effective and efficient means of testing GPS receivers and the systems that rely on them by generating the same signals transmitted by GPS satellites, thus GPS receivers process the simulated signals in exactly the same way as signals from actual satellites. A GPS simulator provides control over the signals generated over the global test environment, so that testing can be conducted in controlled laboratory conditions

A GPS simulator provides a superior alternative for testing compared to using actual GPS signals in a live environment. Unlike live testing, testing with simulators provides full control of the simulated satellite signals and the simulated environmental conditions. With a GPS simulator, users can easily generate and run many different scenarios for diverse kinds of tests, with complete control over:

• Date, time, and location
• Vehicle motion
• Environmental conditions
• Signal errors and inaccuracies

WHY USE A GPS SIMULATOR?

Testing with simulators is the widely accepted best practice for validating the performance of GPS receivers and systems, in many different scenarios and operating conditions in a controlled laboratory environment. Simulators are used extensively in academia and industry, in virtually all GPS receiver manufacturing and major system integration and in many different application fields, including navigation, positioning, telecommunications, aviation, automotive, and space, for both civilian and military applications. Using simulators facilitates several stages of research and product development, including requirements analysis, design and development, integration, production, maintenance, and support.

GPS SIMULATION BENEFITS

GPS simulators provide many benefits, including:

Control	Completeness	Reliability	Efficiency
Flexibility	Repeatabality	Cost	Realism

GPS and GNSS Simulators provide the only effective means of testing new and future GNSS capabilities that are not yet supported by actual constellations, such as the GPS L2C and L5 signals and the Galileo system.

GPS TESTING

• The GSS8000 Multi-GNSS Constellation Simulator provides GPS/SBAS, GLONASS and Galileo signals. GPS configurations can also support QZSS and SBAS. Classified signals and various options are also available.
