A GPS navigation message subframe is a segment of digital data transmitted by GPS satellites to provide positioning and timing information to receivers.
A SHA-256 digest is a unique digital fingerprint generated from input data using the SHA-256 cryptographic hash algorithm.
Measurements, assumptions & sources +
GPS navigation message subframe
Subframe payload size: 37.5 B; exact conversion.
A legacy GPS navigation-message subframe contains 300 transmitted bits, equivalent to 37.5 bytes. The fractional byte is an exact bit-count conversion, not a claim that the radio message is stored byte-aligned.
Defined examples — our methodology
The marked subframe payload size is calibrated. Unmeasured illustration details are representative.
SHA-256 digest
Binary digest size: 32 B; standard.
A SHA-256 digest is exactly 256 bits, or 32 bytes. Text hexadecimal representation usually occupies 64 ASCII characters.
The marked binary digest size is calibrated. Unmeasured illustration details are representative.
