Here's the fuller reply I promised earlier.
The code makes 2 assumptions:
a. there is only one carrier in the environment (which I will change to
allow more in the future).
b. In the carrier_nav.dat file each carrier is assigned a unique frequency
which corresponds to a TACAN channel. This will not change
The code takes the channel # and searches for the corresponding frequency,
then uses this frequency to search carrier_nav.dat. Using the first match it
comes to (assumption b. above) it searches the property tree to find the
name of the carrier (assumption a. above). If the name of the carrier found
is a substring of the entry in carrier_nav.dat, then it has found a valid
entry, and will measure range and brg.
Some points to note:
If the entry in carrier_nav.dat is:
12 999 999 100 11160 0.000 CDG FNS Charles de Gaule
TACAN
then
<name>Charles de Gaule</name>
<name>de Gaulle</name>
or even
<name>de</name>
all produce a valid entry. The entry is NOT enclosed in quotes.
No
"en->name = entry_node->getStringValue("name", "Nimitz");"
is not a mistake. If <name></name> is not specified, then it defaults to
"Nimitz". If <name></name> is specified then it uses that instead.
As I said, it works here. If you set log-level=debug you might be able to
see all this happening, as there are several debug points set within this
code. Make sure you have a well-formed carrier_nav.dat, that it is gzipped,
and <name></name> is correct.
HTH. Let me know how you get on
Vivian
