Member Data Documentation

◆ a

std::array<double, 3> NAV::GalileoEphemeris::a

Polynomial coefficients for clock correction

a(0) bias [s]
a(1) drift [s/s]
a(2) drift rate (aging) [s/s^2]

Note: See [13] GAL-ICD-2.0, ch. 5.1.3, p. 46

◆ BGD_E1_E5a

double NAV::GalileoEphemeris::BGD_E1_E5a

E1-E5a Broadcast Group Delay [s].

◆ BGD_E1_E5b

double NAV::GalileoEphemeris::BGD_E1_E5b

E1-E5b Broadcast Group Delay [s].

Note: See [13] GAL-ICD-2.0, ch. 5.1.5, p. 47f

◆ dataSource

std::bitset<10> NAV::GalileoEphemeris::dataSource

Data sources.

Bit 0 set: I/NAV E1-B Bit 1 set: F/NAV E5a-I Bit 2 set: I/NAV E5b-I Bits 0 and 2: Both can be set if the navigation messages were merged, however, bits 0-2 cannot all be set, as the I/NAV and F/NAV messages contain different information Bit 3 reserved for Galileo internal use Bit 4 reserved for Galileo internal use Bit 8 set: af0-af2, Toc, SISA are for E5a,E1 Bit 9 set: af0-af2, Toc, SISA are for E5b,E1 Bits 8-9 : exclusive (only one bit can be set)

Note: See [37] RINEX-3.04, ch. A8, p. A25

◆ IODnav

size_t NAV::GalileoEphemeris::IODnav

Issue of Data of the nav batch.

The navigation data is disseminated in data batches each one identified by an Issue of Data. In nominal operation the navigation data (ephemeris, satellite clock correction and SISA) have limited validity duration depending on the data type. The identification of each batch by an Issue of Data (IOD) value enables:

the users to distinguish the data in different batches received from each satellite
to indicate to the user receiver the validity of the data (which have to be updated using new issue of navigation data)
the user receiver to compute the full batch of data even if it misses some pages or start receiving the data somewhere during the transmission

Note: See [13] GAL-ICD-2.0, ch. 5.1.9.2, p. 51

◆ signalAccuracy

double NAV::GalileoEphemeris::signalAccuracy

SISA (Signal in space accuracy) [m]

Signal – In – Space Accuracy (SISA) is a prediction of the minimum standard deviation (1-sigma) of the unbiased Gaussian distribution which overbounds the Signal – In – Space Error (SISE) predictable distribution for all possible user locations within the satellite coverage area. When no accurate prediction is available (SISA = NAPA), this is an indicator of a potential anomalous SIS.

Note: See [13] GAL-ICD-2.0, ch. 5.1.12, p.58

◆ svHealth

SvHealth NAV::GalileoEphemeris::svHealth

Signal Health.

Note: See [13] GAL-ICD-2.0, ch. 5.1.9.3, p. 52
