4.5. Real Time Operation
4.5.1. 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=gt300,0,0004
“0” means to get the latest successful GPS fixing time.
The terminal sends the following acknowledgement message:
+ACK:GTRTO,135790246811220,LGT,0004,20090202170812,000A,0102070202
The terminal then reports the latest successful GPS fixing time to backend server as following:
+RESP:GTLGT,135790246811220,20090202091014,20090202170812,000A,0102070202
4.5.2. 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 the terminal:
AT+GTRTO=gt300,1,0004
“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,135790246811220,RTL,0004,20090202172647,000A,0102070202
The terminal will then report the real time position to backend server with the following
commands:
+RESP:GTRTL,135790246811220,1,0,0,1,0.0,189,32.0,6,121.354647,31.222080,200902270713
27,0460,0000,18d8,3072,00,000f, 0102070202
4.5.3. Get All Configuration
Example:
If the backend server wants to get all configurations of the terminal, send the following command
