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, without user interaction.

Checks that the GNSS receiver can receive and process the navigation signal of standard precision in L1 band of GLONASS and GPS GNSS to determine vehicle coordinates and its velocity
Checks that the GNSS receiver outputs the navigation parameter data to
external devices in NMEA-0183 format
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
Checks that the receiver can utilize PZ-90 and WGS-84 coordinate systems
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
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

radio frequency signal is switched off for a specified time and the recovery
time is measured after the signal was switched on
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 measurement time must not exceed the specified threshold

Key Features
5.12 - Tracking and acquisition sensitivity

5.14 - Check cutoff angle

5.15 - Checking power-off
time of navigation module
Verifies the sensitivity of the GNSS navigation module in signal acquisition
mode and in tracking mode. The minimum navigation acquisition power is
determined by decreasing the signal power stepwise. Afterwards the minimum power is ascertained until the receiver loses signal tracking. Caution:
For this test, a precise calibration of the signal path is necessary.
Checks the supported observation data update rate. All required NMEA-0183
sentences must be received with same data rate.
Checks that the receiver excludes satellites from the position calculation if
the satellite is below the set minimum elevation angle because low-elevated
satellites degrade the position calculation
Evaluates the power-off time of the GNSS navigation receiver after the power
is switched off. The difference between actual and set switch-off time is verified

3 Test Setup
The following figure provides an overview of the test setup. In this example, the instrument an R&S SMBV100A is used. The test setup with another supported instrument is
similar.
Test Setup
The test setup comprises the following components:
●
An instrument, providing GNSS signals to the IVS for positioning.
Connect the RF output port of the instrument to the RF port of the IVS (GNSS
receiver).
●
A computer executing the R&S CMWrun.
The computer controls the instrument via SCPI connections (typically LAN). It controls the IVS typically via vendor-specific commands on a serial port interface.
●
External attenuator is recommended for levels below -120 dBm, refer to "External
Power Attenuation" on page 20.
