Aspen Electronics has a series of three GPS simulators. The Pendulum GSG-L1 and GSG-55 generate one and sixteen GPS signals respectively, and are aimed at a wide range of R&D, product development and production test applications.

The single channel GSG-L1 is intended for simple, fast, go/no-go factory tests of GPS-receivers integrated into other devices such as mobile phones, navigation devices and tracking systems.

Sensitivity of the GPS receiver is tested via the programmable output level.

The 16-channel, GSG-55 has the additional capability of performing accurate testing of navigation parameters as a minimum of 16 channels is required for positioning data.  The GSG-55 can also be used to simulate user movements and is suited for both R&D and production test. 

The benchtop unit is portable and requires no external PC control. The front display and control panel of the GSG-55 can be used to edit position, time, trajectory, events (such as signal outtakes), signal data content (ephemeris/almanac), etc.
