1.188 STARFIREMODE (ASCII)
SF-3050 Sapphire SF-3040
This command directs the receiver to use the StarFire GPS service or the StarFire GNSS
service, or both. The StarFire GPS service uses GPS satellite corrections contained in the
legacy type 10 correction message, and the StarFire GNSS service uses both the GPS and the
GLONASS satellite corrections contained in the new type 14 correction message. In addition, if
this command specifies both, the receiver calculates both, but uses the StarFire GNSS
calculations, backing off to use the StarFire GPS calculations if the receiver cannot succeed in
computing the position using the Starfire GNSS corrections.
Command: [STARFIREMODE] gps_gnss
Parameter Definition
GPS Keyword that directs the receiver to use the StarFire GPS service
GNSS Keyword that directs the receiver to use the StarFire GNSS service
BOTH Keyword that directs the receiver to use both the GPS and the GNSS service

This command is not supported in the SF-3040 in this release.

If the receiver operates in single-frequency mode and uses the BOTH keyword, the
position output in Starfire mode will use the StarFire GPS service only from the
legacy type 10 message.
Examples:
[STARFIREMODE] GPS
Use only GPS satellites
[STARFIREMODE] GNSS
Use GPS and GLONASS satellites
[STARFIREMODE] BOTH
Use GPS and GLONASS satellites unless there is a data error, in which case use
GPS satellites
