away from the G1 signal.
 G2 Doppler (c/s): The representation (in cycles per second) of the motion toward or
away from the G2 signal.
 P1 Doppler (c/s): The representation (in cycles per second) of the motion toward or
away from the P1 signal.
 P2 Doppler (c/s): The representation (in cycles per second) of the motion toward or
away from the P2 signal.

Doppler consists of the coarse Doppler from the satellite block adjusted by the
delta Doppler in each of the associated signal blocks. To generate the true
Doppler, add the coarse Doppler to the delta Doppler. Refer to the Sapphire
Technical Reference manual (see Related Documents in the fore-matter).
 StarFire Status
The SFSTATUS1B message tracks the status of each of the StarFire Satellite signals.
Figure 55: StarFire Status Screen
 Signal Strength: This field represents the signal to noise ratio for the StarFire channel
in dB/Hz. The LSB represents 0.25 dB/Hz.
 Good Packet Percentage: This field displays percentage of good packets in received
StarFire data. It is updated every 20 seconds.
 Idle Packet Percentage: This field displays percentage of idle packets in received
StarFire data. It is updated every 20 seconds.
 Re-synchronization Counts: This field represents the StarFire parser packet framing
re-synchronization count.
 Signal Status: Indicates if the signal is being tracked.

TRCK (green background) indicates that the signal is locked in.

IDLE indicates that the signal is not being tracked.

SGDP indicates that the signal is being detected.

SGDF (red background) indicates that the signal has failed.

ACQ indicates that the signal is being acquired.

PLIN indicates the signal is being pulled in.
