Aspen Electronics is now offering a series of easy to use and cost-effective GPS simulators in the UK. One and sixteen GPS signals are generated by the GSG-L1 and the GSG-55 Simulators respectively, aimed at production test applications, product development and R&D applications.
GSG-L1
GPS simulators are now becoming an indispensable test instrument for system integrators mainly because it is not easy to capture GPS signals in indoor sites such as laboratories and factories, where the verification and development work is carried out. Even though getting signals from roof mounted antennas is possible, it is not fully controlled as only limited repeatability to testers is provided. This solution can also not simulate arbitrary times or places and movements, or change atmospheric conditions.
Mobile phones and other handy computing and communication devices along with cameras and games now use integrated GPS technology as a standard feature. Moreover, there is a huge demand for GPS- based applications in the market, such as fleet management, navigation devices for vehicles, tracking of people, goods in transit and personal belongings, personal training devices and road tolls. Normally, only specialists such as GPS R&D community and the Chip manufacturers have been able to afford the GPS simulator. But now there is a growing demand for a low cost version of the equipment for manufacturing test applications and product development among system integrators and OEMs.
The single channel GSG-L1 is aimed at simple, rapid, go or no go factory tests of GPS receivers, which have been integrated into devices such as navigation, tracking devices and mobile phones, while the 16 channel GSG-55 has an additional capacity of performing precise testing of navigation parameters and also the ability to replicate user movements suitable for both production and R&D tests. Its features include a set of pre-installed scenarios, such as basic trajectories, ability to stimulate a series of atmospheric conditions, built in support for multiple antenna models along with 3GPP A-GPS test scenarios and multipath simulation.
