Public Attributes  
uint32_t  time_sec 
GPS (UTC) time, in seconds and microseconds since the epoch.  
uint32_t  time_usec 
GPS (UTC) time, in seconds and microseconds since the epoch.  
int32_t  latitude 
Latitude in degrees / 1e7 (units are scaled such that the effective resolution is roughly 1cm).  
int32_t  longitude 
Longitude in degrees / 1e7 (units are scaled such that the effective resolution is roughly 1cm).  
int32_t  altitude 
Altitude, in millimeters.  
double  utm_e 
UTM WGS84 coordinates, easting [m].  
double  utm_n 
UTM WGS84 coordinates, northing [m].  
uint32_t  quality 
Quality of fix 0 = invalid, 1 = GPS fix, 2 = DGPS fix.  
uint32_t  num_sats 
Number of satellites in view.  
uint32_t  hdop 
Horizontal dilution of position (HDOP), times 10.  
uint32_t  vdop 
Vertical dilution of position (VDOP), times 10.  
double  err_horz 
Horizonal error [m].  
double  err_vert 
Vertical error [m]. 
Member Data Documentation

Altitude, in millimeters. Positive is above reference (e.g., sealevel), and negative is below. 

Latitude in degrees / 1e7 (units are scaled such that the effective resolution is roughly 1cm). Positive is north of equator, negative is south of equator. 

Longitude in degrees / 1e7 (units are scaled such that the effective resolution is roughly 1cm). Positive is east of prime meridian, negative is west of prime meridian.
