LRIT Header Description
As described in File Header Processing, the LRIT File Header actually contains several header types with different sizes. All headers has at least three starting bytes that represent the type and size of header:
Field | Type | Description |
---|---|---|
Type | uint8_t | Type of header (see table below) |
Size | uint16_t | Size of the entire header (include these fields) |
Data | ? (depends on type) | Data of the header (depends on type) |
Table 1 - Basic LRIT Header Structure
All the descriptions of headers will not include these two fields (type and size) since its common to all headers. The headers can be divided into two groups:
- Primary Header
- Secondary Headers
