Description:
The use of a multi-channel simulator as the core of any test approach for systems with a GPS receiving capability yields tremendous benefits in verification and evaluation of all aspects of equipment performance.
The STR4500 multi-channel GPS simulator from Spirent GSS represents a real breakthrough in technology, and provides an easy-to-use but powerful solution for a wide range of testing requirements.
Application areas where the STR4500 excels are vehicle tracking and telematics, civil aviation, marine, personal navigation, telecommunications and space. The STR4500 is particularly suited to a production environment, running standard tests, but is equally at home when performing tests in the field, during incoming goods inspection or generating statistical data from multiple test runs.
A quality test environment requires a simulator to provide accurate and repeatable signals, where the user is in control and where the data needed to assess almost any possible scenario is available at any time. The STR4500 GPS simulator meets or exceeds all these requirements.
The simulator offers exceptional repeatability, wide dynamic capability in both Doppler and power level, low phase noise, code/carrier coherence and a large number of signal channels to support all-in-view and multi-path environments.
In addition, full Satellite Based Augmentation System (SBAS) functionality for WAAS, EGNOS and MSAS is included.
The simulator is supplied with Spirent's graphical SimPLEX software pre-installed on a high-performance Windows® 2000 desktop or laptop computer controller. (NOT INCLUDED!)
A comprehensive range of pre-prepared simulations is supplied on CD-ROM (not included), and additional variations of these can be obtained from Spirent GSS via our website. For maximum flexibility, users of STR2760 & STR4760 simulators can develop scenarios for download to an STR4500 via a range of media.
