For EGNOS : PRN<prn>_y<YYYY>_d<doy>_h<hour>.ems
For WAAS : Geo<prn>_<GPSWeek>_<dayOfWeek>
Note: WAAS files do not have a file extension.
Should the files downloaded from the ftp server do not meet these format requirements, it will
be necessary to rename the files accordingly.
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 scenario,
together with the SAIF message files. This way the user can ensure that the simulated satellite pos
ition based on Rinex NAV files is in line with the position information transmitted 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 82, or during scenario execution (see "Setting Transmit Power" on page 107).
Caution: To learn more about signal level compliance in the United States, see
"Signal Power Level Considerations" on page 23 . 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 .
