1 Key features
The test suites R&S SMx-K360 provide ERA-GLONASS tests with the sequencer tool
R&S CMWrun. The tests are performed on a connected in-vehicle system (IVS) for
ERA-GLONASS. The tests are as closely aligned with the selectable test specifications
as possible. You can select the test specification GOST 33471 or GOST R 55534.
The test equipment simulates a global navigation satellite system (GNSS). The
R&S CMWrun controls the test equipment via SCPI commands and the IVS typically
via vendor-specific commands. The test cases can be performed fully automatic, with-
out user interaction.
Table 1-1: Supported test cases
Test case Test purpose
5.1 - Availability of position/
velocity for GLONASS L1
Checks that the GNSS receiver can receive and process the navigation sig-
nal of standard precision in L1 band of GLONASS GNSS to determine vehi-
cle coordinates and its velocity
5.2 - Availability of position/
velocity for GPS L1
Checks that the GNSS receiver can receive and process the navigation sig-
nal of standard precision in L1 band of GPS GNSS to determine vehicle
coordinates and its velocity
5.3 - Availability of position/
velocity for combined GPS/
GLONASS L1 processing
Checks that the GNSS receiver can receive and process the navigation sig-
nal of standard precision in L1 band of GLONASS and GPS GNSS to deter-
mine vehicle coordinates and its velocity
5.4 - Verify NMEA trans-
mission from DUT
Checks that the GNSS receiver outputs the navigation parameter data to
external devices in NMEA-0183 format
5.5 - Functional RAIM test Checks the receiver autonomous integrity monitoring (RAIM) algorithm by
degrading the pseudo range of several satellites over time in the simulated
signal. The satellites are biased over time and detected satellites must be
neglected after exceeding the specified threshold
5.6 - Use different refer-
ence systems (PZ-90/
WGS-84)
Checks that the receiver can utilize PZ-90 and WGS-84 coordinate systems
5.7 - Location accuracy
(static receiver)
Estimates the error in the evaluation of the plane view and altitude in the
autonomous static mode. A static location is simulated and the error between
actual and determined location is calculated
5.8 - Location accuracy
(moving receiver)
Estimates the error in the evaluation of the plane view, altitude and velocity in
the dynamic mode. A certain trajectory is simulated and the error between
actual and determined location as well as the velocity error is calculated
5.9 - Minimum update rate
of NMEA stream
Checks that received message time delta between adjacent sentences does
not exceed the specified threshold
5.10 - Reacquisition time Evaluates the restore time for signal tracking for a certain GNSS constella-
tion after tracking was lost due to signal blockage. To simulate blockage, the
radio frequency signal is switched off for a specified time and the recovery
time is measured after the signal was switched on
5.11 - Time-to-first fix
(TTFF) under cold start
conditions
Determines the time to first navigation fix for a reset receiver. The ephemeris
and almanac data from all satellites are cleared and thus, the receiver has to
gain all data and the time to first fix is measured. The averaged measure-
ment time must not exceed the specified threshold
