QZSS L1 SAIF
The QZSS satellites transmit also a SBAS signal, called L1 SAIF. The GSG unit can emulate
this signal. The signal is enabled by setting the value of “QZSSL1SAIF” to ”1” in a scenario
file.
If the user does not specify a file containing the messages for transmission, the unit will
transmit only the default (MT63) messages. The naming convention for the transmitted
files is the same as for the WAAS satellites above. The PRN numbers reserved for QZSS
L1 SAIF transmission start from 183, so the name of the message file for J01 should start
with “Geo183_”, for J02 with “Geo184_”, etc.
For the best results, the user should specify the Rinex navigation file(s) used in the scen-
ario, together with the SAIF message files. This way the user can ensure that the simulated
satellite position based on Rinex NAV files is in line with the position information trans-
mitted in the L1 SAIF messages.

3.6.1 Transmit Power
The term Transmit Power refers to the satellite signal power (signal level) transmitted by
GSG during the execution of the currently chosen scenario.
The Transmit Power can be adjusted as described under "Adjusting Transmit Power" on
page 88 , or during scenario execution (see "Setting Transmit Power" on page 113 ).
Caution: To learn more about signal level compliance in the United States,
see "Signal Power Level Considerations" on page 24 . If you live in other
countries, check your local emission standards.
The transmit power is specified in dBm .
The supported range is: Max. -65 dBm … min. -160 dBm .
The resolution is: 0.1 dBm .
Default setting: -125.0 dBm .
Note: The External Attenuation setting decreases the set Transmit
Power level.
