SECTION 2
OPERATIONAL CHARACTERISTICS
This section describes the basic operational characteristics
of the GPS 35/36. Additional information regarding input
and output specifications are contained in Section 4.
2.1 SELF TEST
After input power has been applied to the GPS 35/36 and
periodically thereafter, the unit will perform critical self test
functions and report the results over the output channel(s).
The following tests will be performed:
1) RAM check
2) ROM test
3) Receiver test
4) Real-time clock test
5) Oscillator check
In addition to the results of the above tests, the GPS 35/36
will report software version information.
2.2 INITIALIZATION
After the initial self test is complete, the GPS 35/36 will begin
the process of satellite acquisition and tracking. The
acquisition process is fully automatic and, under normal
circumstances, will take approximately 45 seconds to
achieve a position fix (15 seconds if ephemeris data is
known). After a position fix has been calculated, valid
position, velocity and time information will be transmitted
over the output channel(s).
