ESTING OF THE
TT-3000LRIT
It is recommended that the TT-3000LRIT signal path is tested. This
can be done by requesting a LESO in the Inmarsat-C system to
perform a PVT (Performance Verification Test) on the mobile under
test.
The LESO operator returns the result of the test, which is either that
the mobile passed or failed the test. A written result might look like:
Test Id Group Start time End time Overall result
pvt test ssm subsystem 20031028 15:07:45 20031028 15:17:07 finished pvt
Any further requirements for testing are defined by the Flag State
authority.
