C_ltc_v1, C_ltc_lsb, I_ltc_v1, C_ltc_v0, I_ltc_v0 ← Degradation Factors
Set the degradation parameters for long-term correction:
"I
ltc_v1
, C
ltc_v1
,
C
ltc_lsb
"
Apply if both offset and velocity are included in the messages (that is
MT
24 and MT
= "On").
"I
ltc_v0
, C
ltc_v0
"
Apply if only offset is included in the messages (i.e. Velocity Code =
0).
I_geo, C_geo_lsb, C_geo_v ← Degradation Factors
Set the degradation parameters for GEO navigation message data I
geo
, C
geo_lsb
and
C
geo_v
.
C_er ← Degradation Factors
Sets the extra "catch-all" degradation parameter C
er
.
RSS_iono, C_iono_step, C_geo_v, I_iono ← Degradation Factors
Define the degradation of the ionospheric corrections, as a function of:
"RSS
iono
"
The root-sum-square flag.
"C
iono_ramp
, I
iono
" The rate of change and the minimum update interval for ionospheric
corrections.
"C
iono_step
"
The bound on difference between successive ionospheric grid delay
values.
RSS_UDRE ← Degradation Factors
Sets the root-sum-square flag RSS
UDRE
, necessary to calculate the fast and long-term
correction degradation.
C_covariance ← Degradation Factors
Sets the degradation factor c
covariance
, necessary to calculate the additional term
ε
c
that
is broadcasted in MT
28.
