GPS Module

A DIVISION OF TRIMBLE

68 Using the Optional Modules

Note

Note that the GPS metadata includes a built-in comma delimiter, so

technically,

latlon is 2 output fields, not 1.

In our demonstration application, if GPS is enabled and the module is available on a

configured slot, the GPS latitude and longitude data will be available in tag metadata

output format as below

tag{epc=0xdeadbeafdeadbeafdeadbeaf protocol=GEN2 ant=1 readcount=5

rssi=-79 frequency=926750 timestamp=2014-07-21T10:03:07.587 phase=2

gpio=1111 lat=17.260672 lon=78.236042 }

When the GPS data is not available, for example, when the GPS module is not locked to

the satellite to provide valid data, the tag metadata output data format will only show a

placeholder, such as shown here:

tag{epc=0xdeadbeafdeadbeafdeadbeaf protocol=GEN2 ant=1 readcount=5

rssi=-79 frequency=926750 timestamp=2014-07-21T10:03:07.587 phase=2

gpio=1111 lat=N/A lon=N/A }

1 2 ... 63 64 65 66 67 68 69 70 71 72 73 ... 143 144
