4.10. Real time Operate
4.10.1. Get the Latest Successful GPS Fixing Time
If the terminal has finished a successful GPS fixing, it will record its latest corresponding UTC
time. The backend server can get the UTC time by using the
AT+GTRTO
command.
If the GPS fixing fails after the terminal is powered on, the backend server will get the default
GPS time.
Example:
AT+GTRTO=gl100,
0
,20090202170812
“
0
” means to get the latest successful GPS fixing time.
The terminal sends the following acknowledgement message:
+ACK:GTRTO,357344020001500,
LGT
,20090202170812,20090202170812,000a,0102100203
The terminal then reports the latest successful GPS fixing time to backend server as following:
+RESP:GTLGT,357344020001500,
20090202091014
,20090202170812,000a,0102100203
4.10.2. Real time Locate
Example:
If the backend server wants to get the real time location of the terminal, it can send the following
command to terminal:
AT+GTRTO=gl100,
1
,20090202172647
“
1
” means to get the real time location of the terminal.
The command is accepted by the terminal when the backend server receives the following
message:
+ACK:GTRTO,357344020001500,
RTL
,20090202172647,20090202172647,000a,0102100203
The terminal will then report the real time position to backend server with the following
commands:
+RESP:
GTRTL
,357344020001500,0,0,0,1,0.0,189,32.0,6,121.354647,31.222080,200902270713
27,0460,0000,18d8,3072,00,000f,0102100203
