Class Orion::SimSatClient¶

ClassList > Orion > SimSatClient

#include <SimSatClient.hpp>

Public Static Functions¶

Type	Name
bool	fetchMapboxImage (uint8_t * rgbOut, uint32_t outWidth, uint32_t outHeight)
bool	fetchPosition (double & lat, double & lon, double & alt)

Private Static Functions¶

Type	Name
const char *	getBaseUrl ()
size_t	headerCallback (char * buffer, size_t size, size_t nitems, void * userp) libcurl header callback: captures the mapbox_metadata header value.
size_t	writeCallback (void * contents, size_t size, size_t nmemb, void * userp) libcurl write callback: appends received data to a std::string buffer.

Detailed Description¶

Plain C++ utility wrapping libcurl to fetch data from the SimSat REST API. Not an F-Prime component; hence, called directly by NavTelemetry and CameraManager. Uses standard C++ types to avoid depending on F-Prime headers.

Public Static Functions Documentation¶

function fetchMapboxImage¶

static bool Orion::SimSatClient::fetchMapboxImage (
    uint8_t * rgbOut,
    uint32_t outWidth,
    uint32_t outHeight
)

Fetch a Mapbox image for the current satellite position from SimSat, decode the PNG, resize to outWidth x outHeight, and write RGB bytes into the caller's buffer. GET /data/current/image/mapbox -> PNG bytes + mapbox_metadata header Returns true on success (image available and decoded), false otherwise.

function fetchPosition¶

static bool Orion::SimSatClient::fetchPosition (
    double & lat,
    double & lon,
    double & alt
)

Fetch the current satellite position from SimSat. GET /data/current/position -> {"lon-lat-alt": [lon, lat, alt], ...} Returns true on success, false on HTTP or parse failure.

Private Static Functions Documentation¶

function getBaseUrl¶

static const char * Orion::SimSatClient::getBaseUrl ()

Returns the SimSat base URL from env var ORION_SIMSAT_URL, defaulting to "http://localhost:9005".

function headerCallback¶

libcurl header callback: captures the mapbox_metadata header value.

static size_t Orion::SimSatClient::headerCallback (
    char * buffer,
    size_t size,
    size_t nitems,
    void * userp
)

function writeCallback¶

libcurl write callback: appends received data to a std::string buffer.

static size_t Orion::SimSatClient::writeCallback (
    void * contents,
    size_t size,
    size_t nmemb,
    void * userp
)
