inline |
Read-in constructor.
| [in,out] | buf | Deserialization buffer. Read the descriptor payload from buf. The end of read is the end of the binary payload. If any kind of error is reported in the buffer or if the payload is not completely read, the deserialization is considered as invalid. |
|
overridevirtual |
This method populates this object from XML attributes and sub-element.
| [in] | element | The element whose attributes and sub-elements are parsed to construct this object |
Implements ts::SAT::SAT_base.
|
overridevirtual |
This method converts this object to XML by populating necessary attributes and sub-elements into the provided element.
| [in,out] | root | The element whose attributes and sub-elements are added to to represent values in this object |
Implements ts::SAT::SAT_base.
|
overridevirtual |
This method serializes the attributes of a geostationary satellite.
| [in,out] | buf | A PSIBuffer with the appropriate size for the section payload. |
Implements ts::SAT::SAT_base.
|

| [in,out] | buf | Deserialization buffer. Read the descriptor payload from buf. The end of read is the end of the binary payload. If any kind of error is reported in the buffer or if the payload is not completely read, the deserialization is considered as invalid. |
Implements ts::SAT::SAT_base.
| uint32_t ts::SAT::cell_fragment_info_type::cell_fragment_id = 0 |
The identifier of this cell fragment.
It can occur multiple times in consecutive sections if the signalling is spanned over multiple sections.
| bool ts::SAT::cell_fragment_info_type::first_occurence = false |
Indicates that this section is the first section in a sequence of 1 or more sections that contain the information for the cell fragment.
When this bit is set to 1, it is the first section of the sequence. When it is set to 0, it is not the first section.
| bool ts::SAT::cell_fragment_info_type::last_occurence = false |
Indicates that this section is the last section in a sequence of 1 or more sections that contain the information for the cell fragment.
When this bit is set to 1, it is the last section of the sequence. When it is set to 0, it is not the last section.
| std::optional<int32_t> ts::SAT::cell_fragment_info_type::center_latitude {} |
18 bits - tcimsbf.
The current center of the cell fragment on earth in the WGS84 datum in units of 0.001 degrees. Northern latitudes shall be stated as a positive number, southern latitudes as negative. The range is evidently +/- 90 degrees.
| std::optional<int32_t> ts::SAT::cell_fragment_info_type::center_longitude {} |
19 bits - tcimsbf.
The current center of the cell fragment on earth in the WGS84 datum, in units of 0.001 degrees. Eastern longitudes shall be stated as a positive number, western longitudes as negative. The range is evidently +/- 180 degrees.
| std::optional<uint32_t> ts::SAT::cell_fragment_info_type::max_distance {} |
24 bits.
Indicates the maximum distance on the surface of the earth from the center of the cell-fragment in units of 1 meter that is still considered to be part of the cell fragment
