Horizontal Dilution Of Precision

gps_VDOP

Vertical Dilution Of Precision

gps_lat

Latitude in NDEG - +/-[degree][min].[sec/60]

gps_long

Longitude in NDEG - +/-[degree][min].[sec/60]

gps_elv

Antenna altitude above/below mean sea level (geoid) in meters

gps_speed

Speed over the ground in kilometers/hour

gps_direction

Track angle in degrees

gps_declination

Magnetic variation degrees (Easterly var. subtracts from true course)

gps_year

Years since 1900

gps_mon

Months since January - [0,11]

gps_day

Day of the month - [1,31]

gps_hour

Hours since midnight - [0,23]

gps_min

Minutes after the hour - [0,59]

gps_sec

Seconds after the minute - [0,59]

gps_hsec

Hundredth part of second - [0,99]

gps_smask

Mask specifying types of packages from which data has been obtained

gps_sig

GPS quality indicator (0 = Invalid; 1 = Fix; 2 = Differential, 3 = Sensitive)

gps_fix

Operating mode, used for navigation (1 = Fix not available; 2 = 2D; 3 = 3D)

These measurement labels are arrays, where the indexed element points to the same satellite
(E.g. gps_info_satsigstrength[3] tells the receiving signal strength of satellite 3. Satellite 3 has the
SAT-ID given in gps_info_satid[3].)

Measurement label

Function

gps_info_satid[ ]

Satellite PRN number

gps_info_satinuse[ ]

Used in position fix

gps_info_satelevation[ ]

Elevation in degrees, 90 maximum

gps_info_satazimuth[ ]

Azimuth, degrees from true north, 000 to 359

gps_info_satsigstrength[ ]

Signal, 00-99 dB
