BARCELONA, Spain, Feb. 12 /PRNewswire/ -- With a new software option
from Rohde & Schwarz, manufacturers of mobile devices with built-in GPS
receivers can simulate and test all GPS scenarios and conformance test
cases defined by the A-GPS (assisted GPS) protocol. The option is available
for the R&S SMU200A and R&S SMATE200A vector signal generators as well as
for the R&S AMU200A baseband signal generator.
To accelerate the accurate positioning of a GPS receiver after it has
been switched on, A-GPS-capable mobile devices simultaneously obtain
navigation data both from the satellite and from a mobile radio network.
Utilizing the mobile radio network can reduce initial positioning time from
several minutes (in the worst case) to just a few seconds. This time
advantage is truly useful in situations such as emergency calls.
The new A-GPS signal generator option from Rohde & Schwarz enables
manufacturers to select the GPS scenarios specified for A-GPS conformance
tests in just a few keystrokes. The signal generator is then configured
automatically. In addition, manufacturers can easily and flexibly configure
their own scenarios. Position, navigation data, and up to eight satellites
can be configured to meet individual requirements. To simulate moving
receivers, manufacturers can define the route to be traveled utilizing
popular mapping applications such as Google Earth(R), and then store the
data in the signal generator.
In addition to standard-compliant A-GPS conformance tests,
manufacturers can also make measurements such as Go/No-Go tests or
sensitivity tests. Go/No- Go tests verify whether a GPS receiver can
determine its position correctly. Sensitivity tests check the minimum power
at which a GPS receiver can detect the satellite.
The R&S SMU200A, R&S SMATE200A, and R&S AMU200A signal generators are
the only instruments presently on the market that can generate both mobile
radio signals and GPS signals in realtime. Manufacturers can therefore test
the normal functionality of their mobile phones as well as the positioning
function of their GPS receiver by using just one instrument.
To generate the signals of up to eight satellites, the following test
setup is required: one signal generator with two basebands, two GPS options
(R&S SMU-/R&S SMATE-/R&S AMU-K44), and the A-GPS option. The setup also
requires a protocol tester such as the R&S CRTU, which simulates the mobile
radio connection required for A-GPS. Control data is exchanged between the
signal generator and the protocol tester.
The A-GPS option (R&S SMU-/R&S SMATE-/R&S AMU-K65) is now available
from Rohde & Schwarz.
