The gps interface provides access to an absolute position system, such as GPS.
struct player_gps_data : The gps interface gives current global position and heading information; the format is:
GPS (UTC) time, in seconds and microseconds since the epoch.
Latitude, in 1/60 of an arc-second (i.e., 1/216000 of a degree). Positive is north of equator, negative is south of equator.
Longitude, in 1/60 of an arc-second (i.e., 1/216000 of a degree). Positive is east of prime meridian, negative is west of prime meridian.
Altitude, in millimeters. Positive is above reference (e.g., sea-level), and negative is below.
|int32_t utm_e, utm_n;|
UTM WGS84 coordinates, easting and northing (cm).
Quality of fix 0 = invalid, 1 = GPS fix, 2 = DGPS fix
Number of satellites in view.
Horizontal dilution of position (HDOP), times 10
Horizonal error (mm)
Vertical error (mm)
