3.5 Jupiter binary data messages
This section describes the binary data messages
of the Jupiter GPS receiver. All output and input
binary messages are listed in Table 3-4 together
with their corresponding message IDs. Power-up
default messages are also identified.
Binary messages are transmitted and received
across the host port serial I/O interface (RS-232),
default communication parameters are: 9600 bps,
no parity, 8 data bits, 1 stop bit
3.5.1 Binary output message descriptions

binary messages.

3.5.1.1 Message 1000 (geodetic position status
output)
This message outputs the receiver's estimate of
position, ground speed, course over ground, climb
rate, and map datum. A solution status indicates if
the solution is valid (based on the solution validity
criteria), the type of solution, and the number of
measurements used to compute the solution.
The polar navigation flag is used to indicate that
the solution estimate is too close to the North or
South Pole to estimate longitude. When this flag
is true, the longitude and true course outputs are
invalid and are not updated. Users operating near
the poles should use the 'ECEF position status
output' message. (See Table 3-5.)
