Module dprs 

D-STAR Position Reporting System (DPRS).

DPRS is the APRS-equivalent for D-STAR. Position reports are carried as a special slow-data text block whose payload starts with $$CRC then APRS-style fields.

Reference: ircDDBGateway/Common/DPRSHandler.cpp:120-260 and ircDDBGateway/Common/APRSCollector.cpp:371-394 for the CRC algorithm (CRC-CCITT with reflected polynomial 0x8408, initial value 0xFFFF, final ~accumulator).

Structs

DprsReport

A parsed DPRS position report.

Latitude

Latitude in decimal degrees, in -90.0..=90.0.

Longitude

Longitude in decimal degrees, in -180.0..=180.0.

Enums

DprsError

DPRS sentence parser errors.

Functions

compute_crc

Compute the DPRS CRC-CCITT over the given bytes.

encode_dprs

Encode a DprsReport into a DPRS sentence with a correct $$CRC<hex> checksum.

parse_dprs

Parse a DPRS sentence into a DprsReport.
