This field identifies the GNSS
signal for the GNSS as identified
by ‘GNSS identifier’ for which the
base station is requested to include
the GNSS satellite health
information in the corresponding
response element. This field
consists of 8 bits, each of the
LSB's representing one GNSS
signal, as specified in Table 2.2.65. If the base station is requested
to include the GNSS satellite
health information for a particular
signal, the corresponding bit in
‘GNSS signal identifier’ field is set
to‘1’; otherwise, the bit is set to
‘0’. Bits for which no signal is
defined in Table 2.2.-65 shall be
set to ‘0’.
This element is optional. If this
element is absent, the base station
is requested to include the GNSS
satellite health information for the
signal corresponding to bit 1 in
Table 2.2.-65 of the particular
GNSS identified by ‘GNSS
identifier’.

Description
The base station shall set the bit to
‘1’ if the corresponding SV is
unhealthy and to ‘0’ if the
corresponding SV is healthy or not in
orbit. The least significant bit (bit 1)
represents GNSS satellite ID number
‘0’ for the GNSS identified by
“GNSS identifier” and specified in
Error! Reference source not
found.. The most significant bit (bit
64) of this field represents GNSS
satellite ID number ‘63’ for the
GNSS identified by “GNSS
identifier” and specified in Error!
Reference source not found..
This field is of variable length, and
the base station shall set the
maximum length of this field not to
exceed the defined maximum GNSS
satellite ID number specified in
Error! Reference source not
found..
The base station shall set the bit to
‘1’ if the corresponding SV is not in
orbit and to ‘0’ if the corresponding
SV is in orbit. The least significant
bit (bit 1) represents GNSS satellite
ID number ‘0’ for the GNSS
identified by “GNSS identifier” and
specified in Error! Reference
source not found.. The most
significant bit (bit 64) of this field
represents GNSS satellite ID number
‘63’ for the GNSS identified by
“GNSS identifier” and specified in
Error! Reference source not
found..
This field is of variable length, and
the base station shall set the
maximum length of this field not to
