4.3.49 SIMulation:LNAV:WRITE
The SIM:LNAV:WRITE command must be issued to store the ionospheric/UTC parameters and
ephemerides most recently uploaded by SIM:LNAV:ION and SIM:LNAV:EPH to nonvolatile
(EEPROM) memory. After issuing SIM:LNAV:WRITE, the command SIM:LNAV:SELECT USER
may be transmitted to select the uploaded navigation data for simulation.
4.3.50 SIMulation:LNAV:EEPROM?
The SIM:LNAV? query returns a list of all ionospheric/UTC and ephemeris parameters stored in
EEPROM. The 24-bit words are returned one at a time in the form of individual SIM:LNAV:EPH
and SIM:LNAV:ION commands.
4.3.51 SIMulation:LNAV:ACTIVE?
The SIM:LNAV? query returns a list of all ionospheric/UTC and ephemeris parameters actively used
in the current simulation. The 24-bit words are returned one at a time in the form of individual
SIM:LNAV:EPH and SIM:LNAV:ION commands.
4.3.52 SIMulation:LNAV:SELect
The SIM:LNAV:SELect command determines whether internally-generated navigation data or
user-uploaded navigation data is used for simulation. The format of this command is:
SIMulation:LNAV:SELect <SYNTH | USER>
SYNTH mode selects the internally generated synthesized constellation with circular orbits and
precisely 12 hour orbit periods. This is the default mode.
USER mode selects the user-uploaded ephemeris and ionospheric/UTC parameters.
4.4 SIMulation?
This query command will output the query results from the following queries:
SIM:MODE?
SIM:STATE?
SIM:HOLD:MODE?
SIM:HOLD:STATE?
SIM:HOLD:LIMIT?
SIM:TRACE?
