R&S®SMATE-K44 Digital Standard GPS
- Overview
- Features & Benefits
In Generic Mode, static satellites with constant Doppler shifts are provided for simple receiver tests, like for example sensitivity tests.
In Localization Mode dynamic satellites according to a real almanac file are simulated. Hence, the connected GPS receiver can obtain a valid 3D position fix at a user-defined location. The whole configuration of visible satellites and the generation of the ephemeris out of the uploaded almanac is done automatically by the R&S®AMU200A. The user only needs to specify time and location. So, a realistic scenario with an optimal satellite constellation, i.e. a minimum Position Dilution of Precision (PDOP) is achieved.
The GPS functionality of the R&S®SMATE200A can be enhanced with the option Assisted GPS R&S®SMATE-K65. It is only available for 2-path instruments equipped with two GPS options R&S®SMATE-K44. The option R&S®SMATE-K65 enhances the R&S®SMATE-K44 with functionalities required for A-GPS test scenarios for 3GPP FDD and GSM. However, the R&S®SMATE-K65 is not limited to be used in A-GPS testing exclusively. For testing of stand-alone GPS receivers it is useful as it allows to simulate moving receivers and offers the possibility to create user-defined GPS scenarios. Full flexibility is offered on the simulated satellites including definition of the satellites’ orbits, the complete navigation message and the ionospheric model of each satellite.
