6 :
day
090346 : Current time in UTC
N
: N for North, S for South to indicate the latitude
3546569: the latitude in degree. This number can be shown in DMD (NEMA) or DMS
that is selectable with a command. The identifier will appear on the later part of the
data. In the DMD (NEMA) system it means 35’46.569”, in DMS it means 35’46”56.9’’’.
E
: E for East, W for west to indicate the longitude.
13918458: The longitude in degrees. In DMD 139’18.458”, in DMS 139’18’’,45.8’’’.
+0218
: Altitude, It indicates the altitude in meters. Same as Geoid for NEMA format.
004
: GPS receiver’s speed in km/h.
013
: The direction of the GPS receiver in degrees. 000 stands for 0 degrees north, up to 360 degrees
clockwise.
950701, 6, 090345: The date, day and time when the receiver detected latitude, longitude,
altitude, speed and direction. Time is usually indicated 1 second before the
actual time.
D
: DOP value. Uses characters [A] to [Q] to indicates relative values.
4
: The dimension process mode. [3] stands for the 2-dimension measurements, [4] for
3-dimension measurements.
B
: Location ID. B stands for Japan, Korea
DHIFG to CCOCH: the status of satellites being received on each channel. This example shows the
status of the satellites received in channels 1 to 8 to receive data. Each 5 letters defines 1 channel. The
first letter shows the satellite number, 2
nd
shows the elevation angle, the 3
rd
shows direction angle, 4
th
shows channel status and 5
th
shows the signal-level of each satellite.
D
: The status of the internal oscillator of the GPS receiver.
DH
: not related to the user.
1
: DMS/DMD identifier. Letters for DMS, numbers for DMD.
0
: Parity. [0] for o, [E] for 1.
<CR><LF> end of the data
5-4-2 SMATC
This format is used for SONY’s car-navigation system “Columbus”. The GPS receiver by itself is not yet
available. Accordingly no further information is available, and NO DATA IS AVAILABLE FROM SONY TO
THE PUBLIC. DO NOT CONTACT SONY FOR DETAILS. The string with SMATC and ends with <CR><LF>,
fixed 130 bite fixed data. Similar information to “SONY” format would likely be contained.
5-4-3 $GPGGA
This is one of NMEA-0183 compatible formats. The EJ-50U can analyze and re-structure this format.
It starts with $GPGGA followed by the numbers. They indicate:
GPGGA - Global Positioning System Fix Data
String: $GPGGA,123519,4807.038,N,01131.324,E,1,08,0.9,545.4,M,46.9,M, , *42

1 Fix quality: 0 = invalid
1 = GPS fix
2 = DGPS fix
08 Number of satellites being tracked
